30 minutes closed from the last thunder heard, I do believe, is the rule they use. I have been there when thunder started and they do make you get out of the pool.
The last time I was there and it started lightning, they closed it because the pool wasn't grounded. I doubt if they've corrected that oversight but definitely call and see. It doesn't matter if it's indoors, it has to be grounded
Its an indoor pool. I haven't known it to close in storm weather but I don't go very often anymore. Call and see..
