Hurricane Ida has caused insurmountable damage and is responsible for a growing death count in susceptible U.S. states. There are some areas of the country that seem to be persistently more susceptible to storms and hurricanes than others.

Three key ingredients are needed for a hurricane to form: warm sea surface water that’s at least about 80 degrees Fahrenheit (26.5 C), a thick layer of moisture extending from the sea surface to roughly 20,000 feet and minimal vertical wind shearso the thunderstorm can grow vertically without interruption. These prime conditions are often found in ...
Early in the season, in June and July, sea surface temperatures are still warming and atmospheric wind shear slowly decreases across the open Atlantic. Most early-season hurricanes develop in a small area of the Caribbean and Gulf of Mexico where prime conditions begin early. They typically form close to land, so coastal residents don’t have much t...
The shape of the seafloor can also play a role in how destructive hurricanes become. Hurricane strength is currently measured solely on a storm’s maximum sustained wind speeds. But hurricanes also displace ocean water, creating a surge of high water that their winds push toward shore ahead of the storm. This storm surge is often the greatest threat...
A few years ago, the National Oceanic and Atmospheric Administration analyzed the probability of U.S. coastlines’being hit by a tropical storm based on storm hits from 1944 and 1999. It found that New Orleans had about a 40% chance each year of a tropical storm strike. The chances rose for Miami and Cape Hatteras, North Carolina, both at 48%. San J...
As sea surface temperatures risewith the warming of the planet, more areas outside of these usual hurricane regions may see more tropical storms. I analyzed tropical cyclones in the North Atlantic that made landfallfrom 1972 to 2019 to look for changes over the past half-century. During the first six years of that period, 1972-77, the Atlantic aver...
