Tropical Storm Melissa was moving slowly through the Caribbean Sea early Thursday, said forecasters warning of "life-threatening flooding," and landslides.

Hurricane Melissa is on track to rapidly strenghten and could become a major Category 5 hurricane, according to the NHC, Saturday, Oct. 25.

Melissa could be one of the most intense, devastating hurricanes on record in Jamaica, with widespread flooding, landslides and destructive winds. Flooding rain is also a grave concern in Hispaniola.

Tropical Storm Melissa, responsible for multiple fatalities in the Dominican Republic and Haiti, is nearing hurricane strength, sparking concerns over severe flooding, powerful storm surges, and extensive wind damage in Jamaica and surrounding regions.

According to the hurricane center, Melissa has a significant possibility of making landfall on Jamaica as a major hurricane and could maintain major hurricane strength when it reaches eastern Cuba. Forecasters say Melissa poses little to no risk for Florida and the U.S. at this time.
