Does North America have a hurricane season?

Recently FEMA Director David Richardson claimed he was unaware that there is a hurricane season in the United States.  There most certainly is such a season. The Atlantic hurricane season climatologically runs from June 1 through November 30, with the most active part of the season being mid-August through mid-October. Hurricanes are tropical storms over the Atlantic Basin (Atlantic Ocean, Caribbean Sea, and Gulf of Mexico). Based on a 30-year climate period from 1991 to 2020, the average Atlantic hurricane season has 14 named storms, 7 hurricanes, and 3 major hurricanes. A developing tropical cyclone is given a name when it reaches sustained winds of 39 mph and it becomes a hurricane at 74 mph.

Hurricanes can occur outside this season but these are the months with favorable conditions for formation of the storms. One such condition is the ocean temperature exceeding 79.7F, which is common in the Atlantic Basin between June and November. Hurricanes have difficulty forming off the U.S. west coast due to cold water, cold currents, and unfavorable winds. Continue reading

Was Hurricane Beryl a special storm?

All hurricanes are special, given the extensive damage they can cause when they make landfall. Beryl was considered extra special because it was a record-breaking storm.

Beryl rapidly intensified from a tropical storm to a major hurricane (Category 3 or higher) with wind speeds that increased to 95 mph in less than two days. Category 3 storms have sustained winds between 111 mph and 129 mph. Only six other Atlantic Basin storms have intensified this quickly and those storms all happened after August, the typical time of year with conditions favorable for hurricanes. Continue reading

Are hurricanes intensifying more quickly?

Hurricane intensities are classified using the Saffir–Simpson scale, which rates hurricanes on a scale of 1 to 5 based on the damage their winds would cause upon landfall. Major hurricanes are those classified as Category 3 and higher on this … Continue reading
