Hurricane Melissa is forecast to become a major hurricane on Sunday with catastrophic flash flooding and landslides in Haiti, the Dominican Republic and Jamaica.

Cuba, the Dominican Republic, Haiti and Jamaica are bracing for Hurricane Melissa. The storm is expected to quickly grow into a powerful category 3 or stronger hurricane.

According to the National Hurricane Center's 4 a.m. Sunday advisory, Category 3 Hurricane Melissa is in the Caribbean Sea, 125 miles south-southeast of Kingston Jamaica and 280 miles west-southwest of Port Au Prince Haiti. The hurricane is moving to the west at 3 mph, with maximum sustained winds of 115 mph.

U.S. forecasters issued a hurricane warning for Jamaica Saturday as Storm Melissa reached hurricane strength, threatening catastrophic flooding in the northern Caribbean.

The base commander on Saturday expanded a previous evacuation order to include “non-mission-essential U.S. citizens.”
