Hurricane Melissa intensified into a powerful Category 5 storm and remained on track to slam Jamaica with a destructive storm surge, damaging winds and life-threatening flash flooding.

Here is Melissa’s forecasted path: Melissa is expected to make landfall in central or western Jamaica late Monday night or early Tuesday morning, likely as a Category 4 or 5 hurricane. Most of the destruction will unfold from noon on Monday to noon on Tuesday.

The eye of Melissa is almost certain to make landfall on the south coast of Jamaica on Tuesday morning and pass over the north coast by Tuesday afternoon. While there is still a slight chance the center of the storm will slide around the island, forecasters say this will have little change in the overall threat.
