Answer
Beach Patrol clears the water and often the open sand when lightning threatens—whistles and announcements move faster than dark clouds inland. Do not re-enter until guards give an all-clear; summer cells pass quickly but unpredictably. Umbrellas and metal chairs should be lowered when thunder is audible.
