The Yosemite Blog posted this this morning.  Gosh dawg I wish we were out there in a nice house atop one of the mountains with lots of food and firewood.  It must be absolutely amazing.

10 FEET of Snow Expected in Sierra

Posted: 17 Jan 2010 06:52 AM PST

The National Weather Service has issued a Winter Storm Warning for the northern Sierra Nevada warning that up to 10 feet of new snow is possible at higher elevations.

“Snow is possible above 7000 feet late today. The snow will increase in intensity and the snow level will lower to near 6000 feet by Monday morning…and 5500 feet Monday night.

Total snowfall through Monday night above 7000 feet will be from 2 to 4 feet…with lesser amounts below 7000 feet depending on the changeover from rain to snow. Gusty winds over and near the crest will create considerable blowing and drifting snow.

Main impact: extremely heavy snow will make travel nearly impossible. If you live or work in the higher elevations…you may be unable to reach your destination…or you may not be able to move to a lower elevation.

Other impacts: this will be a long duration storm…and it is likely to persist well into the week…possibly into next weekend. Total snowfall through friday could be as much as 10 feet above 6000 to 7000 feet. Snow levels wednesday and thursday will lower to 4000 to 4500. (”

Although Yosemite Valley is lower than the expected snow level most of the roads into the Valley are not. Take extra precautions if you have scheduled a trip into the park over the next week. Carry tire chains, extra water, food, blankets and warm clothes. Make sure you leave an itinerary with someone you can count on to report you missing if you don’t check in. Don’t take any unnecessary risks.

If you’re staying in Groveland or Oakhurst and don’t want to chain up consider taking Highway 49 to Mariposa and taking Highway 140 into the park. It’s very scenic and usually not as snowy. Your innkeeper will be able to suggest alternate routes.
