We are debating about leaving the auto cover open or closed with the major storm coming. We have a pump that should be able to drain water build up as long as we have electricity. Our grid is fairly reliable and I am hard pressed to think of a time when we had a power outage for any extended period. But the other concern is tree debris and possible punctures to the cover. If we leave the pool open, we know we will have A LOT of leaves to clear out. If we close it we run a small risk of a branch flying over and potentially puncturing the cover. It would be a no brainer if we had trees directly over the pool, but they are all off to the side. What do you think?
