While Ernesto will stay hundreds of miles off the East Coast, rip currents and high waves will be possible from Florida to Maine. Here are some safety tips.

Rip currents are strong channels of water flowing from near the coast out past the surf zone that can pull the strongest swimmer into the deep waters. During hurricane season, especially peak hurricane season, rip currents can become more common as the tropical systems approach or pass the coastline bringing strong wind and wave activity.

First, check the flags before you get into the water. If you see double red flags, stay out of the water! Yellow flags mean moderate surf and currents, while single red flags mean high surf and currents. If you aren't sure whether it's safe to get in the water, ask a lifeguard before heading in.
