Hurricane Matthew Bears Down on Caribbean, US Partially Evacuates Guantanamo Base

Hurricane Matthew packs 130 mph winds, up to 40 inches of seen rain in spots.

— -- Hurricane Matthew inched its way toward several Caribbean countries on Monday, churning northwest at just 5 mph over the warm waters of the Caribbean with maximum sustained winds of 130 mph.

In Jamaica, government officials are making a strong appeal for residents in flood-prone areas to evacuate.

"The greatest concern is the widespread threat of catastrophic flash flooding," said ABC News meteorologist Daniel Manzo.

"This will likely produce life-threatening flash flooding and mudslides in a region that does not have the infrastructure to deal with it," Manzo warned.

Storm surge could be as high as 15 feet in the Bahamas and up to 11 feet in Haiti. Waves and rip currents will create life-threatening ocean conditions throughout the region.

"We have no choice but to prepare ourselves ... to take a frontal assault," Culpepper told the AP.

The last hurricane to make landfall in Haiti was Gustav, a Category 1 storm in 2008.

At this time, it is too early to tell whether the East Coast of the United States will be affected.
