The pool may close during a swim session due to extreme weather, i.e., lightning, thunder, hail, or tornado watches or warnings. When the pool closes due to any of these factors, the pools will remain closed until 30 minutes have passed without thunder being heard or lightening being spotted. . If the air temperature is 68 degrees at the beginning of a day session or falls to this temperature during the session, management reserves the right to close the pool(s) depending on all weather conditions.
