On Wednesday, Hurricane Erin was several hundred miles off the coast of Florida and beginning to push storm surge and deadly rip currents toward the shore. Two other systems may form right behind.

The storm, off North Carolina, was generating life-threatening surf and rip currents and causing beach closures along the East Coast.

Hurricane Erin weakened overnight but remains a major hurricane, according to the latest advisory from the National Hurricane Center. A major hurricane is one that's a Category 3 or higher, with maximum sustained winds of at least 111 mph.

Hurricane Erin weakened to a Category 3 hurricane during the early hours of Aug. 19 as it moves closer to the East Coast, according to the National Hurricane Center. As of 5 a.m. Aug. 19, Erin was located 675 miles southwest of Bermuda and 750 miles from Cape Hatteras,

Hurricane Erin is expected to grow as it moves over the Atlantic through the week, causing dangerous rip currents, heavy rain, and strong winds along the East Coast.
