A high surf advisory was issued by the National Weather Service on Thursday at 2:41 p.m. valid for Saturday between midnight and noon for Mobile and Baldwin counties.

The weather service adds, “Large breaking waves of 5 to 7 feet expected in the surf zone.”

“Breaking waves can sweep people off jetties and docks, and into dangerous seas. Life-threatening swimming conditions and significant beach erosion can be expected. Rip currents can sweep even the best swimmers away from shore into deeper water,” explains the weather service. “Everyone should remain out of the water due to life-threatening surf conditions. Stay off of jetties, piers, and other waterside infrastructure. Swim near a lifeguard. If caught in a rip current, relax and float. Don’t swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.”
