How Hurricane Ian got so powerful — in just two days.

On Monday morning, Hurricane Ian had wind speeds of 75 miles per hour. Just 48 hours later, those speeds had more than doubled. On Wednesday, as the storm made landfall in southwestern Florida, Ian’s wind hit 155 mph — just shy of a Category 5 storm, the most severe category for a hurricane.

Such rapid growth is known by meteorologists as “rapid intensification.” It’s defined as storms whose wind speeds increase by roughly 35 mph or more in less than 24 hours. “Ian definitely met that criteria,” said Paul Miller, a professor of oceanography and coastal sciences at Louisiana State University.

While wind speed isn’t the only force that makes storms dangerous, hurricanes that rapidly intensify are especially worrisome. They can easily catch coastal communities off guard, giving them little time to prepare, Miller said.

So how did Ian get so big, so fast?
