News Flash: So Far, here is what I know. Extreme weather has caused the evacuation of Whitney Portal and the Trail head. They remain CLOSED today. Many hikers on the Whitney Trail were stranded yesterday on the trail. Thunder, Lightening and torrential rain occurred yesterday afternoon and evening over the Crest and down some of the deep Eastern Sierra Canyons. I expect more very adverse weather conditions today. Right now my advise is to stay away from trail heads that lead up into the Sierra. If you want additional information, email me: dmatt123@gmail.com
