The Bridgeport Winter Recreation Area is CLOSED for the season. Thank you for all the support & we will see you next winter.
Clearly we are diving into spring with temperatures reaching 50F above treeline tomorrow. Expect aspects that receive long durations of intense sun to be the most volatile for avalanches. The signs are there look for the clues such as: rollerballs, point releases originating from warm objects, surface shean or icy appearance, runnels, creeping snow, & corn.
There is enough evidence to suggest that cornices are unstable. The unsupported nature of these hazards makes them difficult to predict when they may fail. Avoid being on or under any cornice today, they have a very large destructive potential. Refer to yesterday's observation of a combo cornice fall stepping into Deep slabs leftover from the latest storm system.
Melting at a rate of 2-4" per day is too rapid of a change for the snowpack. Without a refreeze at night due to atmospheric inversions expect snow to remain wet, unconsolidated & in motion. The larger slab avalanche problem is lessening but the Loose wet & Cornice problems are on the rise. Please don't get complacent with the beautiful weather..
Loose wet & cornice avalanches will be the main components of our avalanche hazard for the next few days. Fairly deep wind slabs still exist on isolated leeward features, especially around Leavitt Cirque. Combination Loose wet/ cornice avalanches have been observed. The probability of a human triggering a deep slab is low but cornices falling from ridgelines could tip the scales in dramatic fashion. Rollerballs, wet point releases, stress-cracking, runnels, rivers & previous avalanche debris is showing itself with the rapid melting.

|New snowfall in the last 24 hours:||0 inches|
|Total snow depth:||63 inches|
Warm & dry conditions will exist through the weekend & the middle of next week. We will see high clouds with temperatures reaching 50F degrees. Do not expect the diurnal refreeze at night due to inversions keeping higher elevations in warm air. Wednesday should bring us a weak disturbance possibly followed by some precipitation.
