This past week has been challenging for lifeguards in southern Maine, where rip currents have resulted in multiple rescues. Two challenging scenes involved the rescue of nine children by Ogunquit lifeguards in dangerous, fast-moving currents.

On average, 71 people drown in rip currents every year in the U.S., according to the National Weather Service, though Maine has never reported a rip current fatality.

The major impacts will be felt at the beaches, with high surf expected. A high surf advisory is in effect until 8 p.m. Saturday, with the worst conditions late Friday and into early Saturday morning.
