Atlantic tropical storm and hurricane frequency, by month [27] Approximately 97 percent of tropical cyclones that form in the North Atlantic develop between June 1 and November 30, which delimit the modern-day Atlantic hurricane season. Though the beginning of the annual hurricane season has historically remained the same, the official end of ...
Major hurricanes (Category 3 or above) usually cause the most wind damage. [1] Hurricane Andrew for example caused $45 billion (2005 USD) in damage, most of it wind damage. [2] Although wind damage is rare to tropical cyclones near landmasses, there are a few factors that lead to high wind speeds.
Although the scale shows wind speeds in continuous speed ranges, the US National Hurricane Center and the Central Pacific Hurricane Center assign tropical cyclone intensities in 5-knot (kn) increments (e.g., 100, 105, 110, 115 kn, etc.) because of the inherent uncertainty in estimating the strength of tropical cyclones. Wind speeds in knots are ...
Peak Wind Speed: 190 mph. Deaths: 269. What happened: Allen is considered to be the only hurricane in the history of the Atlantic basin to reach 190 mph of sustained winds. The winds of the storm ...
These warnings use a 1-minute sustained wind speed and can be compared to the Saffir–Simpson hurricane wind scale, however, regardless of intensity in this basin the JTWC labels all systems as tropical cyclones with TC numbers (plus any parenthesized names or placeholders, like typhoons and North Indian Ocean cyclones above).

On Aug. 22, 1992, Hurricane Andrew pummeled southern Florida as a monster Category 5 storm with sustained wind speeds as high as 165 mph and gusts as high as 174 mph. Homes were reduced to piles ...
However, Hurricane Catarina in 2004, to date the only hurricane in the south Atlantic, brought additional review. A subsequent study found that there was an average of 1–2 subtropical or tropical cyclones per year in the Southern Atlantic in recent decades. [30]
Hurricanes spinning across the Atlantic Ocean are now more than twice as likely to strengthen from a weak Category 1 storm to a major Category 3 hurricane in just 24 hours, new research finds ...
