Rapid intensification: How warmer oceans are fueling stronger storms
Warmer oceans are fueling stronger and more costly hurricanes
NASHVILLE, Tenn. (WSMV) - Tropical storms and hurricanes can be devastating no matter their strength. Stronger storms end up being more costly.
The tropics have been active this year and will likely stay active through the rest of the season as wind shear remains relatively weak and ocean temperatures are record-warm at this time.
According to Climate Central, since April 2023, global sea surface temperatures have been continuously hotter than any period on record. Warm ocean waters fuel stronger tropical cyclones.
With record-warm oceans, and higher hurricane activity, come more costly hurricanes. Tropical cyclones are the most costly weather disaster in the U.S. Rapid intensification is playing a role in more costly hurricanes.
Rapid intensification refers to the increase in wind speed of a hurricane by at least 35mph in a 24-hour time span. 80% of major hurricanes (Category 3-5) undergo rapid intensification.
Forecasting rapid intensification is difficult. For this reason, watching and warnings are issued far ahead of a storm making landfall. Some of the most destructive storms to landfall in the U.S. have rapidly intensified before landfall.
Below is a list of storms that have had the most rapid intensification in the 24 hours before making landfall in the mainland U.S.
Of the 63 tropical cyclones that caused at least $1 billion in damage from 1980 to July of 2024, 44 (70%) underwent rapid intensification. The five most costly hurricanes since 1980, all underwent rapid intensification, according to Climate Central.
