Melissa intensified Saturday afternoon into a Category 1 hurricane. It will continue to strengthen before making landfall as a Major Category 4 hurricane in Jamaica on Tuesday. The storm will drop two to three feet of rain on the island, creating catastrophic and life-threatening flash flooding and landslides.

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
