On Thursday at 3:10 a.m. the National Weather Service issued a high surf advisory valid from Friday midnight until Saturday 6 p.m. for Mobile and Baldwin counties.

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

“Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water,” comments the weather service. “Inexperienced swimmers should remain out of the water due to dangerous surf conditions. 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.”
