Hurricane Melissa is set to bring catastrophic winds, flooding and storm surge to Jamaica, forecasters have warned.

A Sarasota County flight crew prepares to deliver relief supplies to Jamaica later this week as catastrophic Hurricane Melissa slams the island.

Haiti is expected to see catastrophic flash floods and landslides early next week causing “extensive infrastructural damage and potentially prolonged isolation of communities.” The southwestern peninsula of Haiti, from the border of the Dominican Republic to Port-au-Prince, was placed under a hurricane watch and a tropical-storm warning.

The Category 5 storm is expected to hit the island on Tuesday. It'll be the strongest storm there since recordkeeping began 174 years ago.

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.
