The Atlantic's most powerful hurricane slams the Caribbean

Early Wednesday morning Hurricane Irma, a Category 5 storm, made landfall in the Caribbean, slamming into Antigua and Barbuda as it barrels toward Puerto Rico and the U.S. Virgin Islands. Irma's heavy rain and strong winds, which have reached a sustained maximum of 185 mph, have made it the most powerful storm ever recorded in the Atlantic. The storm, which the National Hurricane Center has declared "potentially catastrophic," is expected to hit South Florida by Sunday. President Trump has already approved disaster declarations for Florida, Puerto Rico and the U.S. Virgin Islands, all of which are at risk of being hit head on. Meanwhile, two other storms are building momentum in the Atlantic. Tropical Storm Jose is expected to become a hurricane by Wednesday night, and Tropical Storm Katia is strengthening in the Gulf of Mexico.
