Tropical Storm Helene is set to enter the Gulf of Mexico Wednesday afternoon. From there, it’s on a dead sprint to go from tropical storm to Category 3 hurricane — or stronger — in just over 24 hours.

Gov. Ron DeSantis on Tuesday said Florida is preparing for a direct hit from a major hurricane that could intensify quickly before it makes landfall in the Panhandle later this week. The National Hurricane Center predicted a tropical storm currently in the Gulf of Mexico will become Hurricane Helene as it moves north toward Florida by Thursday.

The tropical system in the western Caribbean may not look like much yet, but don’t be fooled. History has shown the Gulf of Mexico can be a pressure cooker, turning systems like this one from wimpy windstorms to devastating monster storms almost overnight under the right conditions.
