Before the Hurricane
Do not empty your pool, or if you feel you really should, only lower it a few inches.
Turn off electricity to pool equipment.
Protect electrical equipment: heaters, motors, clocks, transformers, et al,
with tied-down waterproof covers.
Remove loose items from the pool area. Placing them in the pool can stain and damage your pool’s surface.
Add a shock dose of chlorine to the pool if possible. This will help counteract the possible addition of several inches of fresh water. It may also keep your pool blue if your electricity fails for a day or two and your pump doesn’t work.
Find out from your screen enclosure manufacturer if they recommend removing some opposite side panels, to allow venting.
After the Hurricane
If necessary, and an overflow is imminent, lower the water level of the pool. This is usually not needed because almost all modern pools are built to handle excess runoff.
Remove excessive debris by hand, rake, or net. Don’t turn on the system if there is excessive/severe debris in the pool because this may clog the system.
Make sure the electrical equipment is dry before turning it on.
Clean the filter and run the system continuously until the water is clear.
At the end of the storm, after cleaning up, check the timer and reset it if necessary.
Don’t swim unless you or your tech have checked the chemistry of the pool.
