Why Hurricane Ian Got So Much Stronger, So Quickly

Hurricane Ian Could Cause Billions in Damage in Florida

Many hurricanes grow weaker as they approach land. But Hurricane Ian, like Hurricane Ida last year and a string of other recent hurricanes, did the opposite: Its top winds suddenly grew stronger as the storm neared Cuba, jumping from 65 miles (105 kilometers) per hour to 100 mph in less than a day. Meteorologists call that kind of dramatic shift “rapid intensification” -- and say that climate change appears to be making it more common.

It’s when a storm’s winds increase by 35 mph or more in 24 hours or less, according to the National Oceanic and Atmospheric Administration.
