I have an outdoor GFCI that feeds several downstream outlets that are also outdoors. Recently it has rained pretty heavily and now the GFCI is tripping after about 10+ minutes, not sure if the exact timeframe because it seems to be pretty variable. I'm sure moisture is getting into one of the downstream outlets causing the trip, pretty sure it's not getting the GFCI itself though cause it's well covered. I was wondering if there was a good way to troubleshoot which outlet is the one being affected and causing the trip. Yo complicate things it's a warm day today and things are likely drying out which makes it hard to troubleshoot for the next time it rains. Any help would be appreciated
Edit: yes the downstream outlets and the GFCI have an in-use cover on them.
