MIAMI (AP) — Forecasters say Earl has strengthened into a Category 1 hurricane as it barrels toward several islands in the eastern Caribbean.

Meanwhile, the Category 1 Hurricane Danielle was bringing dangerous rip currents to the East Coast of the United States.

The U.S. National Hurricane Center in Miami said Sunday that Earl could make landfall over the Northern Leeward Islands as soon as Sunday night. It could become a major hurricane by Tuesday.

Forecasters warn that Hurricane Earl could bring battering waves and storm surge reaching up to 3 feet above normal tide levels in some areas. Hurricane warnings and watches had been issued for several islands, and heavy rains could cause flash floods and mudslides.

Earl was 225 miles east of Antigua and had maximum sustained winds of 75 mph.
