Before the storm barreled north over Cuba, at least seven people died across the Caribbean as the storm approached Jamaica. See the storm's impact on Cuba.

Secretary of State Marco Rubio pledges "immediate humanitarian aid" to Cuba as State Department responds to effects of Hurricane Melissa in the Caribbean.

Rescue efforts are underway across the Caribbean after Hurricane Melissa tore through the region as one of the most powerful Atlantic storms in more than 150 years.

Hurricane Melissa is now moving northeast from Cuba after hammering the island with powerful winds and rain. As the storm scrapes Turks and Caicos and the Bahamas with its destructive force, residents in low-lying and flood prone areas have been urged to evacuate ahead of a shelter-in-place order coming tonight.

The strongest storm to directly hit Jamaica before Melissa was Hurricane Gilbert in 1988, which made landfall as a category four hurricane, according to the US National Weather Service. Damaging winds and heavy rain have hit eastern Cuba, according to the latest update from the National Hurricane Center.

Jamaica is expected to be in the storm's eyewall, which refers to the band of dense clouds surrounding the eye of the hurricane. The eyewall generally produces the fiercest winds and heaviest rainfall, according to Deanna Hence, a professor of climate, meteorology and atmospheric sciences at the University of Illinois Urbana-Champaign.

Sagua de Tánamo, a town in Holguín province, awoke to flooding of the Sagua River. In Contramaestre, a town in Santiago de Cuba province, Melissa’s strong winds uprooted trees and tore off sections of sidewalk.
