Melissa is expected to become a Category 5 hurricane by Sunday night, Oct. 26, and have catastrophic impacts on islands in the northern Caribbean.

Tropical Storm Melissa has formed in the Caribbean, making it the 13th named storm in the Atlantic this year, the Miami-based National Hurricane Center announced Tuesday morning. The NEXT Weather team at CBS Miami said no direct impacts are expected to South Florida at this time,

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.

Though the risk to Florida is low, parts of the Caribbean are in peril. Tropical Storm Melissa is expected to power up to a major hurricane. Though its chances of affecting Florida are low, it can't be ruled out.

Melissa is forecast to become a hurricane by Saturday, Oct. 25, and a major hurricane by Sunday, Oct. 26, the Hurricane Center said. Current forecasts predict Melissa will be a Category 4 storm early next week. A major hurricane is one that is a Category 3 or higher, with maximum sustained winds of at least 111 mph.

Some travel plans in Central Florida are being altered due to Tropical Storm Melissa, which is expected to intensify into a hurricane.

Melissa is expected to bring life-threatening and catastrophic flash flooding and landslides to Jamaica and southern Hispaniola through the weekend.

Melissa is now a hurricane, meaning millions in Jamaica are in harm’s way and could see flooded streets, power outages, and more.

Tropical Storm Melissa could reach Category 5 as it rapidly intensifies, with forecasters warning of a potential 'humanitarian disaster' while impacts will be felt as far as Florida next week
