Earl grows to Category 4, new storm forms
Hurricane Earl strengthened into a powerful Category 4 storm on Monday after lashing the northeast Caribbean islands, and was expected to swipe the U.S. East Coast in the next few days, the U.S. National Hurricane Centre said.
While there are currently no hurricane watches or warnings for the U.S. mainland, FEMA urged residents to be prepared for severe weather as projections show the storm could affect states up and down the East Coast.
