Tropical Storm Melissa is expected to rapidly intensify over the weekend into a Category 4 hurricane, according to the National Hurricane Center. The slow-moving storm is forecast to bring "life-threatening and catastrophic flash flooding and landslides to southern Hispaniola and Jamaica through the weekend.

Tropical Storm Melissa is expected to become a major hurricane over the weekend. The storm is currently located in the Caribbean and is not expected to directly hit Florida. Jamaica and Haiti are under hurricane and tropical storm watches and warnings.

Tropical Storm Melissa is lumbering through the Caribbean Sea and bringing a risk of dangerous landslides and life-threatening flooding to Jamaica and southern Hispaniola.

There is no infrastructure in the region that can withstand a Category 5,” Jamaican Prime Minister Andrew Holness said ahead of the storm's landfall.

Category 5 Hurricane Melissa has made landfall already in Jamaica and Cuba, as one of the strongest hurricanes to ever make landfall.

Tropical Storm Melissa is nearly stationary in the central Caribbean, with forecasters warning it could soon strengthen and brush past Jamaica as a powerful hurricane.
