The Bridgeport Winter Recreation Area is CLOSED for the season. Thank you for all the support & we will see you next winter.
Uniquely directional & up to Gale force winds have been active in the Eastern Sierra mountains with the arrival of this Christmas storm. North & Easterly winds have dramatically sculpted the snow & loaded some aspects & terrain features on the South & West. Yesterdays slabs ranged from soft to supportable over a very small area. The elongated fetch of transported snow has an ability to cast wind slabs much lower on the slopes, increasing a travelers ability to remotely trigger avalanches.
We are reporting 5.5-8" of new snow associated with this recent Christmas storm. Uncommon strong winds from the North & East have loaded & crossloaded terrain features facing South & West. Warm temperatures & rain with this system have created good bonding between the new & old snow surface. A gambit of precipitation types have fallen during the snows duration, mostly notably rain & graupel changing the snows surface below 8000'.
Swirling strong winds yesterday were transporting snow to places that have been previously scoured. Well defined cornices & drifts are scattered in irregular fashion from ridgelines into low lying meadows. This storm arrived warm & blustery with rain below 7500'. Associated with this storm a variety of precipitation forms were observed including: Stellars, Wind-Broken Particles, Rime & Rimed Particles, Rain, & Graupel. Sublimation of wind transported snow was also observed. The right-side-up nature of the storm has left some well-bonded new snow to the old snow surface. We have searched for new avalanche activity but have not seen anything substantial.
