At the first indication of thunder or lightning, the manager on duty is authorized to close the pool and direct members and guests to go their vehicles until the pool reopens. (A fully-enclosed, all-metal vehicle is very safe in a lightning storm.) Pool users who do not have a vehicle to shelter in and cannot safely leave may go to the game room under the Community House and near the lifeguards.
The closure time is generally 30 minutes from the last sound of thunder or sight of lightning, but the closure time is at the discretion of the manager on duty.
Parents are responsible for providing transportation, if necessary, for their children in the event the pool is closed.
Please review this advice on swimming pool safety from the National Lightning Safety Institute.
