Hurricane Melissa is now a Category 5 storm, capable of dumping catastrophic rainfall in addition to the powerful winds it's packing. The monster storm has begun to impact Jamaica, Cuba and Haiti, and it's expected to cause life-threatening problems for days during its slow crawl through the Caribbean.

This map from the National Hurricane Center shows the likely path of Hurricane Humberto as it tears through the Atlantic. The hurricane "is drifting slowly in weak steering currents," the center said, though it added that Humberto is "gradually increasing speed while moving west-northward to northwestward".
