BACKPACKER ALERT: February 20, 2017

 Hey Hikers,

Alex here, from Tahoe to Whitney.

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.

Winter to Spring to Summer 2015-16: Depths of Drought to Depths of Flooding?

December 11 2015

Our goal here is to track each stage of the Fall-Winter-Spring transition to Summer conditions. Our main goal is to determine when trails will open to Summer conditions.

As Fall comes to a close certain patterns have manifested themselves. These have set the stage for the advent of Winter. We've seen that the remnants, the tail ends of the tropical fronts hitting the Sierra have put a reasonable Fall coat of snow on the Sierra.
