Tropical Storm Melissa is forecast to become a major hurricane within days. Although the exact track is uncertain, some models bring it close to Florida’s east coast.

Tropical Storm Melissa is barely moving through the Caribbean, and that’s exactly what makes it so dangerous. The longer it lingers, the more rain it dumps. Haiti, Jamaica and the Dominican Republic could face days of relentless downpours and mudslides.

The U.S. National Hurricane Center says Tropical Storm Jerry has strengthened in the Atlantic Ocean on a path toward the Caribbean.
