During the quiescent periods (3000–1400 BC, and 1000 AD to present), a more northeasterly position of the Azores High would result in more hurricanes being steered toward the Atlantic coast. During the hyperactive period (1400 BC to 1000 AD), more hurricanes were steered towards the Gulf coast as the Azores High was shifted to a more southwesterly position near the Caribbean. Such a displacement of the Azores High is consistent with paleoclimatic evidence that shows an abrupt onset of a drier climate in 32: 6528: 840: 66: 1944: 2132: 5470: 768:" can be used interchangeably to describe this weather phenomenon.

However, these measurements are suspect, since instrumentation used to document wind speeds at the time was likely to succumb to winds of such intensity. Nonetheless, their central pressures are low enough to rank them among the strongest recorded Atlantic hurricanes. 2778: 2280:(2008) normalized mainland U.S. hurricane damage from 1900–2005 to 2005 values and found no remaining trend of increasing absolute damage. The 1970s and 1980s had low amounts of damage compared to other decades. The decade 1996–2005 has the second most damage among the past 11 decades, with only the decade of 1926–1935 surpassing its costs. The most damaging single storm is the 1242:. Hurricane Gilbert maintained a pressure of 900 hPa at landfall, as did Camille, making their landfalls tied as the second strongest. Hurricane Dean also made landfall on the peninsula, but it did so at peak intensity and with a higher barometric pressure; its landfall marked the fourth strongest in Atlantic hurricane history. 2288:

destruction and remote landfall limit the number of intense hurricanes in the official record before the era of hurricane reconnaissance aircraft and satellite meteorology. However, the record shows a distinct increase in the number and strength of intense hurricanes; therefore, experts regard the early data as suspect.

These active hurricane seasons predated satellite coverage of the Atlantic basin. Before the satellite era began in 1960, tropical storms or hurricanes went undetected, unless a reconnaissance aircraft encountered one, a ship reported a voyage through the storm, or a storm landed in a populated area.

It has been observed that a poleward migration exists for the paths of maximum intensity of tropical cyclone activity in the Atlantic, as shown by research on the latitudes at which recent tropical cyclones in the Atlantic are reaching maximum intensity.

Although the hurricane season is defined as beginning on June 1 and ending on November 30, tropical cyclones have formed in every month of the year. Since 1870, there have been 32 off-season cyclones, 18 of which occurred in May. In the same period, nine storms formed in December, three in

1774:. The month of September sees an average of 3 storms a year. By September 24, the average Atlantic season features 7 named tropical storms, including 4 hurricanes. In addition, two major hurricanes occur on average by 28 September. Relatively few tropical cyclones make landfall at these intensities. 2246:

While the number of storms in the Atlantic has increased since 1995, there is no obvious global trend. The annual number of tropical cyclones worldwide remains about 87 ± 10. However, the ability of climatologists to make long-term data analyses in certain basins is limited by the lack of

A decrease in wind shear from July to August contributes to an increase in tropical activity. An average of 2.8 Atlantic tropical storms develop annually in August. On average, four named tropical storms, including one hurricane, occur by August 30, and the first intense hurricane develops by 4

According to the Azores High hypothesis, an anti-phase pattern is expected to exist between the Gulf Coast and the Atlantic coast. During the quiescent periods, a more northeasterly position of the Azores High would result in more hurricanes being steered towards the Atlantic coast. During the

Partially because of the threat of hurricanes, some coastal regions had sparse populations between major ports until the advent of automobile tourism; therefore, the most severe portions of hurricanes striking the coast may have gone unmeasured in some instances. The combined effects of ship

However, high vertical wind shear and low 779:

Tropical cyclones can be categorized by intensity. Tropical storms have one-minute maximum sustained winds of at least 39 mph (34 knots, 17 m/s, 63 km/h), while hurricanes must achieve the target of one-minute maximum sustained winds that is 75mph or more (64 knots,

Since 1851, a total of 81 tropical storms and hurricanes formed in June. During this period, two of these systems developed in the deep tropics east of the Lesser Antilles. Since 1870, three major hurricanes have formed during June, such as
