2021 Pacific typhoon season

2254:. The JTWC also upgraded it to a tropical storm at 03:00 UTC. The system had deep flaring convection, however its low-level circulation was broad and elongated. On July 18, at 00:00 UTC, the JMA upgraded the system to a severe tropical storm. In-fa started moving westwards, and as it gradually strengthened, In-fa developed a formative eye on July 20, at 03:00 UTC. At 09:00 UTC, the JTWC declared In-fa to have strengthened into a typhoon as it had deep convection and robust outflow. The JMA also followed suit and upgraded In-fa to a typhoon at 12:00 UTC because of good upper-level outflow and higher sea surface temperatures; however, its central dense overcast was still obscure. On the next day at 03:00 UTC, In-fa strengthened into a Category 2-equivalent typhoon as its central convection continued to deepen. The feeder bands became more compact and the eye of the typhoon became clearer and more defined. The JTWC assessed that it peaked as a Category 2-equivalent typhoon with maximum wind speeds of 175 km/h (110 mph) at 03:00 UTC the same day. Because of dry air, the JTWC later downgraded In-fa to a Category 1-equivalent typhoon at 03:00 UTC the next day despite the presence of warm sea surface temperatures and low wind shear. On July 23 at 21:00 UTC, In-fa got further downgraded to a tropical storm by the JTWC, as its eyewall became fragmented and the deep convection was not continuous over the eye; it later re-intensified into a Category 1-equivalent typhoon again at 03:00 UTC the next day as it regained convective depths and it managed to maintain a ragged eye. At 09:00 UTC, PAGASA issued its final advisory as Typhoon In-fa moved northwards and exited the PAR. On July 24, at 06:00 UTC, In-fa peaked as a typhoon with maximum 10-minute sustained wind speeds of 150 km/h (90 mph) and a minimum pressure of 950 hPa (28.05 inHg), according to the JMA. On the next day, the China Meteorological Administration (CMA) noted In-fa to have made landfall in 3624:

3-equivalent typhoon, and six hours later, the agency had further downgraded it to a Category 2-equivalent typhoon because of the effects of the eyewall replacement cycle and the increasing presence of dry air. At 15:00 UTC of September 28, Mindulle re-intensified into a Category 3-equivalent typhoon, as it moved over favorable conditions. Satellite imagery showed that the typhoon continued to struggle to intensify. Its 20 nmi (37 km; 23 mi) eye had steadily shrunk but it remained cloud covered and ragged. By the next day at 03:00 UTC, the JTWC re-upgraded it to a Category 4-equivalent typhoon as the eye cleared out again. At 21:00 UTC of September 29, it rapidly weakened and by 15:00 UTC the next day, it weakened from a Category 3-equivalent typhoon to a Category 1-equivalent typhoon. Cool dry air and cool sea-surface temperatures were responsible for the weakening. At 21:00 UTC of October 1, the JTWC issued its final warning as it downgraded to a tropical storm. Three hours later, JMA also issued its final warning, as it became extratropical cyclone, off the coast of

4493:. On 00:00 UTC of December 1, the JMA further upgraded it to a severe tropical storm. Fifteen hours later, the JTWC declared it a typhoon and upgraded it to a Category 1-equivalent status, as Nyatoh developed an eye according to microwave imagery. The JMA followed suit at 18:00 UTC. By 03:00 UTC the next day, it further intensified into a Category 2-equivalent typhoon as it briefly formed a ragged eye. Later that day, Nyatoh unexpectedly rapidly intensified to a Category 4-equivalent super typhoon due to jet interaction. It later reached peak intensity with 10-minute sustained winds of 185 km/h (115 mph) and a pressure of 925 mb (27.32 inHg). However, this peak was short-lived as strong wind shear, dry air, and cooler sea surface temperatures shredded the system apart and rapidly weakened to a Category 1-equivalent typhoon at 18:00 UTC. On December 4 at 06:35 UTC, the JMA declared Nyatoh a remnant low. 3077:

the next day as its convection became more organized. Satellite imagery also continued to indicate the presence of a well-defined low-level circulation center. It was downgraded to a tropical depression again on the next day as its low-level circulation center became less defined. On August 16, at 00:00 UTC, the JMA issued its final advisory for the system, losing its tropical cyclone characteristics because of unfavorable conditions. Later at 00:00 UTC, the next day, the JMA started tracking the system again. At 09:00 UTC, the JTWC issued its final advisory as the system's convection became further disorganized despite the presence of a marginally favorable environment. At 19:30 UTC on August 18, the JTWC issued a TCFA for its remnants as its low-level circulation center improved significantly. On August 19, the system was upgraded by PAGASA to a tropical depression, and a few hours later, it received the local name

3463:. At 12:00 UTC, the JMA upgraded it to a severe tropical storm. At the same moment, Chanthu started its rapid intensification as it quickly became a minimal typhoon. Several hours later, the typhoon reached Category 4-equivalent status, and by the next day at 09:00 UTC, it reached Category 5-equivalent intensity, developing a 5 nmi (10 km; 5 mi)-wide eye which was surrounded by very compact, intense convection. After reaching its initial peak, Chanthu was downgraded to a Category 4-equivalent super typhoon as its pinhole-shaped eye started to fade. However, by September 10, Chanthu began to re-intensify as its eye began to clear up. Chanthu further intensified into a Category 5-equivalent super typhoon once again at 09:00 UTC that day. On 05:00 PHT on September 11 (21:00 UTC on September 10), the PAGASA reported that Chanthu passed to the east of the 2552:. Nine hours later, the agency further upgraded the system to a subtropical storm as vigorous deep convection further became constant on the east of the still-exposed and elongated circulation center. By July 24, Nepartak was guided north-northeastwards by an upper-level low and a trough. Baroclinic interaction with the latter also led to the development of a large and asymmetric wind field, with the maximum sustained winds of 35 kn (40 mph; 65 km/h) being far from the center. Later, the system's core became ragged as it turned northwards and further northeast before shifting north again while remaining at that intensity. At 09:00 UTC of the next day, the JTWC noted two distinct vorticities, being spaced 350 nmi (650 km; 405 mi) to each other, with each having an elongated circulation from the south-southwest to the north-northeast. 3991:. At 05:00 PHT of October 13 (21:00 UTC of October 12), the PAGASA issued its final bulletin as its exited the PAR and continued towards Hainan. Between 03:00 and 09:00 UTC of October 13, Kompasu had made landfall over the east coast of Hainan. By 18:00 UTC, the JMA downgraded it to a tropical storm, as it crossed the entire island and entered the Gulf of Tonkin, as its convection had rapidly weakened because of the rough terrain of the island. At 09:00 UTC of the next day, the JTWC issued its final warning followed by downgrading to a tropical depression, as its convection had diminished and the low-level circulation center had been weakened significantly because of the increasing vertical wind shear and dry air, despite not making landfall over northern Vietnam. The JMA issued its final warning after downgrading it to a tropical depression at 18:00 UTC. 4179:. Unexpectedly, Namtheun further intensified into a severe tropical storm according to JMA at 06:00 UTC of October 16, and a Category 1-equivalent typhoon according to JTWC at 09:00 UTC of October 16. Satellite imagery depicted that the system had developed a compact core with improved convection structure near its center. It also developed an eye-like feature. The weakening of the vertical wind shear was main reason for the intensification and also the presence of marginally favorable sea-surface temperatures (26–27 °C (79–81 °F)). A few hours later, both JMA and JTWC downgraded to a tropical storm, as its convection had weakened significantly because of further cooling of sea-surface temperatures and strengthening of the wind shear. Namtheun managed its intensity as it continued north-northwards but since it was interacting with the 2892:. Clusters of convective bursts were gathering around the center with a curved manner, with Mirinae having distinct anticyclonic outflow. At 15:00 UTC, the JTWC followed and upgraded it to a tropical storm, as the storm developed a partially exposed low-level circulation center. Flaring convection was present, though it was affected by moderate westerly wind shear. On August 7, at 18:00 UTC, Mirinae peaked as a tropical storm with maximum 10-sustained wind speed of 50 kn (95 km/h; 60 mph) and minimum barometric pressure of 980 mb (28.94 inHg). Maximum 1-minute sustained wind speed of Mirinae was 55 kn (100 km/h; 65 mph). On August 9, at 09:00 UTC, the JTWC issued its final warning for the system. The JMA later issued its last warning on the next day at 00:00 UTC, as it became an extratropical cyclone. 2673:. At that time, the LLC of the storm remained exposed and its strongest convection or thunderstorms were displaced to the west. A deep-layered subtropical ridge to the east guided the depression to move to the north-northwest while being near from a monsoon gyre. Despite being located in a favorable environment for additional strengthening, another system to the south slowly interacted with the depression, which weakened the storm's intensity. It reached its peak intensity that day, with winds of 55 km/h (35 mph) in the estimates of the JMA and the JTWC. By August 3, the JTWC downgraded 12W to a disturbance as its structure deteriorated; the agency upgraded it back to a tropical depression a day later. The system's LLC then became fully exposed, and on August 6, both the JTWC and the JMA assessed that 12W had dissipated. 4175:. The JTWC recognized it as a tropical depression, three hours later, and six hours later, the JTWC upgraded it to a tropical storm. Namtheun managed to maintain its intensity for two days, until at 09:00 UTC of October 13, it was downgraded to a tropical depression by the JTWC, as it started moving westwards because of the presence of a subtropical ridge towards the southeast of the system. Satellite imagery showed that the deep convection had been displaced towards the northeast and the LLCC of the system had become less defined. However at 15:00 UTC of the next day, the JTWC re-upgraded it to a tropical storm, as it entered over warm sea-surface temperatures which allowed the system to maintain its intensity despite high wind shear. Satellite imagery also indicated that it developed 4395:. On the same day, the JTWC noted the same low pressure area and gave a low chance of formation, which was later upgraded to medium. At 05:30 UTC of October 25, the JTWC issued a TCFA for the system, as its convection had improved and developed a weakly defined LLCC. On the next day, after re-issuing the TCFA at 05:00 UTC, the JTWC upgraded it to a tropical depression at 09:00 UTC as it was located off the coast of Vietnam. Satellite imagery found that its LLCC had become defined however the convective structure continued to remain disorganized. Between 15:00 UTC of October 26 and 03:00 UTC of October 27, the system made landfall near 2347:. At 21:00 UTC, the JTWC declared Cempaka to have strengthened into a Category 1-equivalent typhoon as it developed a ragged 15 nmi (28 km; 17 mi) wide eye. The JMA later upgraded it to a severe tropical storm at 00:00 UTC on the next day. On July 20, at 06:00 UTC, Cempaka peaked as a severe tropical storm with 10-sustained maximum wind speed of 55 kn (100 km/h; 65 mph) with minimum pressure of 990 hPa (29.23 inHg), according to JMA. JTWC assessed that it peaked as a typhoon with maximum 1-minute sustained wind of 80 kn (150 km/h; 90 mph). Cempaka made landfall near 898: 7035: 4301:

discontinued giving advisories to the area of convection, as its convection had completely dissipated. On the same day at 18:00 UTC, the JMA recognized the same area of convection, as a low pressure area. At 15:00 UTC of October 22, the JTWC started giving advisories for the area of convection as it developed sufficient convection and a poorly defined low-level circulation. On the next day at 18:00 UTC, the JMA upgraded it to a tropical depression, and three and a half hour later, the JTWC issued a TCFA. At 03:00 UTC of October 24, the JTWC upgraded to a tropical depression and designated as

3620:

started to rapidly intensify as it quickly intensified into a Category 2-equivalent typhoon. Its eye expanded but became ragged due to the presence of dry air. Mindulle continued its rapid intensification, as it further intensified into a Category 4-equivalent typhoon at 15:00 UTC. Its eye became well-defined and at 03:00 UTC the next day, it became a Category 5-equivalent super typhoon, making it the third super typhoon of this season. Satellite imagery showed that the typhoon had developed a well defined 15 nmi (28 km; 17 mi) eye and deepening of the central core.

4797:

system gradually became more organized with a more defined low level circulation. On June 30, the JTWC issued a TCFA for the system. On July 1, animated multispectral satellite imagery indicated a very broad and ill-defined low level circulation with convection being sheared to the south-southwest of the disturbance, which prompted the JTWC to cancel the system's TCFA and downgrade its development chances within the next day to low. The JMA no longer considered it a tropical depression in their tropical disturbance summary advisories on the same day.

804: 28: 25633: 682: 2983:. On August 7, at 09:00 UTC, the JTWC issued the last advisory for the system, as its low-level circulation center was partly exposed due to the westerlies inflicting shear upon the storm. However, the JMA continued to publish bulletins for the system. Nida continued its trajectory. On August 7, 12:00 UTC, the JMA downgraded it to a tropical storm due to shear and a generally less conductive environment. The JMA further downgraded it to an extratropical low at 00:00 UTC the next day as it completed its extratropical transition. 2360:

JTWC further downgraded Cempaka to a tropical depression as its deep convection declined; however, it still retained a well-defined wind field. After moving inland, Cempaka started moving westward at 00:00 UTC on July 21 due to weak steering flow. Remaining inland, Cempaka maintained tropical storm intensity as it continued westward, but due to unfavorable conditions over land, it weakened into a tropical depression on the next day at 00:00 UTC. On July 22, at 09:00 UTC, Cempaka then moved southwards towards the

3270:, as it developed a weakly defined low-level circulation center. The disturbance gradually intensified, and on September 5, the JMA recognized the system as a tropical depression. Later that day, the JTWC issued a TCFA as its low-level circulation center and its surrounding convection became well organized. The agency recognized the system as a tropical depression around four hours later. At 21:00 UTC, the PAGASA recognized the system as a tropical depression, with the agency assigning it the local name 4205: 4766: 4690: 4115: 3745: 3550: 2436: 1408: 3911: 3393: 2827: 2284: 1141: 4436: 3653: 3208: 1708: 1593: 998: 4252: 4022: 3008: 2698: 2187: 1857: 3983:. However at that time, the JTWC still considered the system as two separate disturbances and issued separate TCFAs later in the day for both depressions, albeit noting the possibility of merging. The JTWC later considered the entire system as merged with their first warning for Kompasu. At midnight of October 11, the JMA upgraded it to a severe tropical storm, as it attained good cloud characteristics. At 12:10 UTC (20:10 PHT), Kompasu made its first landfall near 3183:, as its low-level circulation center became more defined but still partially exposed. The system maintained its defined convective structure, however at 09:00 UTC on September 3, it struggled to consolidate because of presence of dry air causing its convective structure to diminish. At 21:00 UTC, the JTWC issued its final advisory as its remaining convection was sheared by the incoming westerlies. At 12:00 UTC on September 4, the JMA stopped tracking the system. 2917: 26142: 4518: 4339: 3127: 2616: 1978: 1274: 1416: 4123: 3753: 2444: 3558: 3919: 2835: 2292: 1282: 3401: 1716: 4444: 3661: 3216: 1601: 1149: 1006: 3016: 2195: 4260: 4030: 2706: 1865: 2925: 1773:. At 18:00 UTC, the JMA upgraded the storm to a severe tropical storm as it turned northwestwards. At this time, a microwave imagery scan of Champi revealed an eye feature emerging in the system; however, this was short lived as dry air continued to impact the storm from the west. In addition, poleward outflow on the system remained weak on June 24, restricting Champi to significantly develop. However, on the next day, as a 4698: 4347: 3135: 2624: 1986: 4951:'s Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of 65 km/h (40 mph). PAGASA names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has had an international name assigned to it. The names of significant tropical cyclones are retired, by both 4526: 3090:, and low wind shear helped it to develop over the past few hours. The JTWC did the same thing at 21:00 UTC, the same day. At 18:00 UTC the next day, the JMA upgraded it to a severe tropical storm as satellite imagery showed convective bursts gathering around the center in a curved manner; however, shortly after at 06:00 UTC on August 22, it weakened into a tropical storm due to increasing wind shear from the 1914:. On July 6, PAGASA issued its last advisory on Tropical Depression Emong at 03:00 UTC as it moved outside the PAR and also lift up the warnings which were imposed earlier in the wake of Emong. Meanwhile, the JMA soon followed and issued its last advisory. JTWC also issued its last advisory as its convection was significantly sheared and its low level circulation dissipated rapidly over six hours. 4778:, and Visayas on January 18. The JMA, however, discontinued advisories for the system on the next day. The depression also brought stormy weather to Luzon on January 20. The PAGASA warned residents of possible flash flooding and mudslides due to heavy rainfall. The system's precursor was associated with a frontal system, with its combined effects bringing heavy rainfall over much of Visayas, the 24674: 24467: 14123: 12152: 8940: 8415: 4793:. The system gradually developed as it was experiencing warm sea surface temperatures and low vertical wind shear. On the next day at 00:00 UTC, the JMA recognized the system as a tropical depression. On the same day, the JTWC cancelled the TCFA for the system as its structure degraded, with the JMA last recognizing the system as a tropical depression on June 1 at 18:00 UTC. 832:

Tropical Depression Nando also formed in early October but was absorbed by Kompasu. Namtheun initially peaked as a minimal tropical storm while being highly sheared, but unexpectedly conditions became briefly more favorable and peaked as a minimal typhoon. The system transitioned into an extratropical low before explosively intensifying into a bomb cyclone and impacting the

1781:, the outflow increased on the storm which allowed it to intensify further. On June 25, at 06:00 UTC, the JMA officially declared the storm a typhoon. The JTWC soon followed, upgrading it into a Category 1-equivalent typhoon. At this time, a Champi turned north and north-northwestwards, and subsequently reached its peak intensity of 120 km/h (75 mph) ten-minute 3179:. At 06:00 UTC, the JTWC gave a medium chance of formation for the system over the same area, despite being classified as subtropical depression, as it developed a well defined, partially exposed low-level circulation center. At 20:00 UTC, the JTWC issued a TCFA for the system, and at 03:00 UTC the next day, it was upgraded to a tropical depression and was designated as 2876:

around the low-level circulation. At 22:00 UTC, the same day, the JTWC issued a TCFA for the system, as it had a consolidating low-level circulation, and it was located in a very conductive environment with high sea surface temperatures and low to moderate vertical wind shear. On the next day, at 03:00 UTC, the PAGASA recognized it as a tropical depression and named it

2094:. Later, the disturbance began to reorganize; however, strong wind gradient suppressed its intensification, with flaring convection displaced to the west. Nine hours later, the JTWC upgraded the system to a weak tropical depression with maximum sustained winds of 45 km/h (30 mph); the JMA analysed the storm to be at 55 km/h (35 mph) and a minimum 4603:. The PAGASA raised Tropical Cyclone Wind Signal #1 over parts of Eastern Visayas and Northern Mindanao. Later that same day, the JMA upgraded Rai to a typhoon. The PAGASA and the JTWC later followed suit and also upgraded Rai to a typhoon. Rai then rapidly intensified overnight, becoming a Category 5-equivalent super typhoon on the morning of December 16. 1347:(12:20 UTC), Crising made landfall in Baganga, Davao Oriental as a weakening tropical storm. It quickly degraded as soon as it made landfall, with both the JTWC and the PAGASA downgrading it to a tropical depression at 15:00 UTC. At 03:00 UTC on that day, the PAGASA reported that the system degenerated to an area of low-pressure in the vicinity of 2343:, with the storm possessing an improved convective structure and a defined low-level circulation. The JTWC upgraded the system to a tropical storm at 21:00 UTC as it had a defined low-level circulation center with improved banding structure. At 00:00 UTC on July 19, the JMA upgraded the system to a tropical storm, assigning it the name 3278:, with the JTWC following suit three hours later. At 12:00 UTC, the JTWC upgraded it typhoon before downgrading it into a tropical storm at 18:00 UTC. Three hours later, the JMA upgraded it to a severe tropical storm. At the same moment, Conson rapidly intensified into a typhoon according to the PAGASA as it made its first landfall on 1906:

outflow, being induced by an upper-level trough to the northwest. The JMA upgraded the broad and weak system to a tropical depression at 18:00 UTC on the next day, followed by a TCFA being issued by the JTWC an hour and a half later. The PAGASA subsequently upgraded the system to a tropical depression at 02:00 UTC on July 4, naming it

1474:. The JMA assessed the area to have developed into a tropical depression on May 29 at 06:00 UTC. The PAGASA made a similar assessment in a Tropical Cyclone Advisory issued at 15:00 UTC. The JTWC later followed with their own assessment, identifying the center of the newly developed tropical depression and assigning the designation 4171:. The JMA later recognized the same area of convection as a tropical depression on October 9. At 14:00 UTC the same day, the JTWC issued a TCFA for the invest as it developed a flaring convection which was circulating over the obscured LLCC. By midnight of the next day, the JMA upgraded it to a tropical storm and named it 3337:. These conditions made Conson weaken, prompting the JMA to downgrade it to a tropical storm at 12:00 UTC on September 11 to further downgrade it to a tropical depression at 18:00 UTC the same day, with the JTWC downgrading it to a tropical depression at 03:00 UTC on September 12. It stalled off the coast of Vietnam near 1367:

the submission of modules. When Crising made landfall, it caused widespread rains and flooding across Mindanao and Southern Visayas. Gusty winds were also felt in parts of Mindanao where the storm passed. In Baganga, some trees were knocked down by strong winds, while strong winds with heavy rainfall were reported in

2392:, though it was later downgraded to a blue alert as it entered the Chinese mainland. It was later lifted by the CMA, as the threat of Cempaka was minimal. As Cempaka made landfall in Guangdong, there were reports of heavy rainfall and rough waves in the region. Over 990 flights were cancelled in Guangzhou, 3471:

as the storm began to weaken slightly. On September 11, Chanthu began to weaken as it continued to move northwards with the presence of dry air. The PAGASA issued its last bulletin for Chanthu since it exited the PAR on the next day. By September 14, Chanthu was no longer a typhoon as it slowly moved

2978:

Satellite imagery showed that convective bursts were organized into a curved band and that the system was exhibiting good anticyclone outflow. On August 6, at 18:00 UTC, the JMA upgraded it to a severe tropical storm, as it had distinct anticyclonic outflow. Nida then started moving eastwards at 6:00

2359:

Province, and the JTWC downgraded it to a tropical storm at 18:00 UTC the same day as its low-level circulation center became obscure. The JMA also downgraded Cempaka to a tropical storm at 00:00 UTC the next day as it moved further inland and its central dense overcast disappeared. At 09:00 UTC, the

and low wind shear. At 00:00 UTC on June 11, the JMA upgraded the system into a tropical depression. Six hours later, the JTWC issued a TCFA for the system as it began to show characteristics of a monsoon depression. By 18:00 UTC, the JMA upgraded the system to a tropical storm, assigning it the name

1551:

Heavy rains caused floods in parts of Mindanao; 11 fatalities were reported, 3 people were injured, and 2 people are missing. As of June 4, 55,226 people were affected and 16,680 people are inside evacuation centers. A total of ₱307.2 million (US$ 6.39 million) of damages were incurred throughout the

1527:

before moving into the South China Sea. On June 3 at 03:00 UTC, the JTWC upgraded Choi-wan back to a tropical storm. At 03:00 UTC, the PAGASA removed all Tropical Cyclone Warning Signals as Choi-wan moved away from the country. Choi-wan then exited the PAR on June 3 at 18:00 UTC before weakening into

4796:

On June 29, an area of convection formed 425 nmi (787 km; 489 mi) from Guam with satellite imagery revealing that the system had a deep convection with a weak low level circulation. Within a favorable environments with low-to-moderate wind shear, and warm sea surface temperatures, the

4785:

On March 9, a low-pressure area entered the Philippine Area of Responsibility, though it was not expected to develop at that time. On March 14, the low-pressure area intensified into a tropical depression over the Sulu Sea before quickly degenerating back into a low-pressure area. The system brought

2969:

which was moving northwards at 10 kn (19 km/h; 12 mph). At 03:00 UTC, the next day, the JTWC issued a TCFA for the system. By that time, it had developed a partially obscured low-level circulation center. At 15:00 UTC, the JTWC recognized it as a tropical depression, designating it as

2875:

On August 3, at 18:00 UTC, the JMA issued a tropical cyclone advisory for a tropical depression which was located off the east coast of Taiwan and north of the Philippines. The JMA later issued its first prognostic reasoning at the same time, stating that clusters of convective bursts were scattered

2372:

in Vietnam and later entered the Gulf of Tonkin at 03:00 UTC. However, Cempaka further weakened despite the presence of warm sea surface temperatures because of high monsoonal wind shear and land interaction. At 15:00 UTC, the JTWC issued its final warning on the system as it became a weakly defined

1225:

of 220 km/h (140 mph), and 1-minute sustained winds of 315 km/h (195 mph). A few days later, on April 22, Surigae began to weaken again, with the storm's structure deteriorating and its large eye dissipating. Soon afterward, all of the remaining convection was sheared to the east

650:

On June 23, the PAGASA released their monthly climate outlook for the rest of 2021, predicting 5 to 9 tropical cyclones developing or entering their area of responsibility from July to September, and 5 to 8 tropical cyclones from October to December. TSR issued an update to their forecast on July 7,

4977:

During the season, 22 tropical storms developed in the Western Pacific and each one was named by the JMA, when the system was judged to have 10-minute sustained windspeeds of 65 kilometres per hour (40 mph). The JMA selected the names from a list of 140 names, that had been developed by the 14

3076:

as satellite imagery depicted developing spiral bands and a defined low-level circulation center. The system briefly became a tropical storm; However, at 21:00 UTC, the JTWC downgraded it to a tropical depression as its convection struggled to organize itself. It regained its intensity at 09:00 UTC

1342:
