DARE COUNTY, NC -- The warm weather makes a swim in the Ocean all the more appealing.
There's danger in the water Monday, the National Weather Service says, from rip currents.
The threat is high for beaches from Virginia Beach to Duck, NC.
Rip currents are strong, narrow channels of water that flow out to sea and can quickly pull even the most experienced swimmers out. If you become caught in a rip current, remain calm. Try to swim parallel to the beach until you get away from the rip and then swim at an angle in to shore. Officials stress that you should not try to swim back to shore directly against the rip because it can exhaust and even kill the strongest swimmer.
Other tips for safety in the water include swimming only where a lifeguard is on duty, pay attention to the red flags and signs warning of dangers and to heed instructions from lifeguards.
