You are herebackpacker alert
This Alert will be in effect as long as this massive snowpack sits upon the Crest. That is uncertain, but will likely last through at least the middle of July, depending on weather. Good chance for this snowpack to see next season's Winter.
We face the Spring Thaw. Below I discuss where we are and what I see as the most important factors controlling how Spring will play out into Summer. I link to the resources necessary to track these factors.
The questions we address here are first, fording conditions and safety, then trails, specifically, "when will the trails open for PCT hikers and hikers geared for Summer travel?"

Sorry about the delay contacting you. I have had a series of distracting personal events while Nature has cut loose. Nonetheless, I have been tracking the wild weather across the Backpacker News Pages on the Forum and the Backpacker's Calendar on the Trail Guide. I hope you've checked them out and found them useful and informative.
