I'm heading up to San Jac tomorrow for the 2nd time this season. Going onto Whitney on the 21st. Down in SD county we had flash flood alerts in the borrego springs area all afternoon. No thunderstomrs on San Jan this afternoon though. Hoping for a clear day tomorrow. I'm planning to be at the trailhead off Humber Park by 7:30am so I shld be off the peak well before the afternoon thunderclouds roll in (if any). Will report otherwise.

Anyone heading up Whitney on a day hike on the 21st or at SJ tomorrow shoot me a PM.

Thanks all for the great posts.
