THIS SNOWPACK SUMMARY EXPIRED ON March 25, 2015 @ 10:04 am
Snowpack Summary published on March 23, 2015 @ 10:04 am
Issued by Adam Babcock - Bridgeport Avalanche Center
Avalanche Character 1: Normal Caution
Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features. Use normal caution when travelling in the backcountry.

Normal caution advised through Tuesday, with the possibility of isolated pockets of Wind Slabs.  I suspect an increase in wet snow instabilities will return to the BWRA Wednesday afternoon through Friday.

Snowpack Discussion

Special Announcement:  I will be out of state Tuesday through Saturday, so there will be no Snowpack Summary this Friday.  The next Snowpack Summary will be issued Friday morning, April 3rd.  BAC's final avalanche clinic will be held at June Mtn Conference Center April 3rd at 6:30pm.  If snow conditions allow, for the field session on Saturday, April 4th, we may be able to host a Mono County Search And Rescue avalanche rescue dog/handler team for a rescue scenario at Sonora Pass.  Watching an avalanche rescue dog at work is a unique experience for anyone who can attend the clinic and participate in the field day...please help spread the word and hope to see you out there!

The Bottom Line for the BWRA:   On Saturday, a moderate freeze overnight, cooler daytime temps, and moderate winds kept the snow surface cool to minimize wet snow instabilities.  Sunday and Monday, harder overnight freezes, cloud cover, and windy conditions similarly stabilized surface conditions.  USMC personnel reported light snow Monday morning, and Leavitt Lake Snotel site shows a couple inches of accumulation, likely not enough to cause significant Wind Slab development, though I will not be in the field today to confirm this prediction.

Cooler temps and windy conditions will continue through Tuesday, with a return to high pressure and well above average temperatures mid-week into the weekend.  Watch for Loose Wet and Wet Slab instabilities to return during this period of re-warming.   


A cold front and low pressure system is affecting the region today and tomorrow with the best chance for snow showers today along the Sierra Crest.  Wednesday through Friday a high pressure ridge builds back into the region, moving eastward Saturday morning, allowing a closed low approaching the California coast to affect the area on Saturday and Sunday.  Forecast details after Friday are uncertain.
