After rain, the first pool check should be the walking path. Look for puddles, slick corners, and any cover edge that now sits where people step.
Move light objects away from drains and low points. If the same spot fills often, keep that area clear rather than treating it as storage.
Check the cover access before lifting anything heavy. A wet cover is more awkward when the first step is already blocked.
The aim is safe movement first, then the usual pool routine.
