Tropical Storm Helene is expected to unleash mudslides and flooding in Cuba before reaching major hurricane strength on Thursday as it hits Florida with life-threatening ocean surge, the U.S. National Weather Service said.

HAVANA (Reuters) - Tropical Storm Helene is expected to unleash mudslides and flooding in Cuba before reaching major hurricane strength on Thursday as it hits Florida with life-threatening ocean surge, the U.S. National Weather Service said.

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.

Another storm system is taking aim at Florida, this time possibly the Panhandle with storm effects all along the Gulf Coast. Tropical Storm Helene, soon to be a hurricane, is sweeping up from the Caribbean Sea into extremely warm waters that are fuel for tropical cyclones.
