Why did we suddenly get concerned with a little water splashing on a plug? If it is too much the GFCI will trip.
BTW is there an in use cover for the second string of Xmas lights you have plugged in the end of f1rst string? How about the plug on the tool you have plugged into the extension cord? That is a lot closer to the user than the receptacle on the wall.
I only have in use covers on the receptacles that will normally have something plugged in them. The ones that are only used for things I will use and put away have snap covers, not wasp condos.
