Hurricane Erin won't make landfall in the U.S., but it will bring dangerous rip currents to the East Coast. Beachgoers from Florida to the Carolinas to the Mid-Atlantic to Long Island need to be on alert for rip currents from Erin this week. A rip current, which flows out toward the ocean, can quickly pull a swimmer away from the shore.

Cruise lines are rerouting ships away from Hurricane Erin, which regained power after weakening over the weekend.

Considering that it's MidAtlantic week, there's a lot in jeopardy.
