The National Hurricane Center said Hurricane Rafael grew into a major Category 3 storm Wednesday and made landfall in Cuba on its way into the Gulf of Mexico, while the Florida Keys remained under a tropical storm warning.

Hurricane Rafael rapidly intensified into a Category 3 hurricane in the Caribbean and is a few hours away from slamming into Cuba. The powerful hurricane is the fifth major hurricane of the year in the Atlantic and the strongest in the basin this late in the year since 2020.

About 17% of crude oil production and 7% of natural gas output in the U.S. Gulf of Mexico was shut in response to Hurricane Rafael, the U.S. Bureau of Safety and Environmental Enforcement said on Wednesday.
