Hurricane Ian has strengthened to a Category 3 storm, and could intensify even more.
Ian has made landfall in Cuba and is expected to cause widespread damage. Destructive winds and coastal flooding, as well as heavy flooding rainfall, are set to continue in Cuba, with the worst conditions expected to last through early Tuesday afternoon before slowly improving thereafter.
The National Hurricane Center says Ian now has sustained winds of 125 miles an hour. The center is just 150 miles southeast of western Cuba.
The country will likely see significant winds and storm surges overnight. Ian could grow even stronger as it goes over the warm Gulf Coast waters. By Thursday, it should be within 10 miles of the Florida coastline near Saint Petersburg.
Watches and warnings have been issued along the state's western coast.
NASA reports they have moved Artemis I from the launchpad to the vehicle assembly building due to the hurricane.
More than 15 million people could see at least tropical-storm-like conditions.
