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 bring catastrophic flash flooding and landslides to parts of the Dominican Republic, Haiti and Jamaica.

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.

Lightning flashes in the eyewall of Category 5 Melissa are a marker of how strong the storm is. It reached a central pressure of 892 millibars, among the lowest ever recorded in the Atlantic Ocean. It is tied as the third-most intense Atlantic storm with the devastating 1935 Labor Day hurricane.

Up to 40 inches of rain, 13 feet of storm surge and 160 mph sustained winds will cause “extensive infrastructure damage” that will cut off communities, the National Hurricane Center warned. Melissa has already killed three people in Haiti and Jamaica each and one person in the Dominican Republic.
