Hurricane Rafael is rapidly intensifying in the Caribbean and is expected to become a Category 3 hurricane before it slams into Cuba Wednesday. As of Wednesday morning, Rafael was a Category 2 storm with winds of 110 mph – just 1 mph away from Category 3 status – and 130 miles from Cuba.

The National Hurricane Center said Hurricane Rafael grew into a major Category 3 storm Wednesday ahead of landfall in Cuba as it headed toward the Gulf of Mexico, while the Florida Keys remained under a tropical storm warning.

Tropical Storm Rafael formed in the Caribbean on Monday, a storm that's predicted to intensify into a hurricane and threaten the Gulf Coast this weekend.
