The only water-related (rain-related) post I could find was for a blown 30 amp fuse in the fuse box and that would prevent a restart so it is NOT YOUR PROBLEM.
On that thread many of us agreed we had never had rain related issues - the fuse box is relatively well protected. Spare fuses are a good idea, as is di-electric grease on them and all connectors. You can do those things later if you haven't already.
I just hope this thing straightens out for you soon, or the rain stops and you can go on. It may not be a srain-related as you think, but let us know when you can.
