Avalanche Problem 1: Normal Caution
  • Type ?

As always, remain vigilant for isolated pockets of instability throughout the range. There may be some small deposits of new snow on S-W aspects from yesterday’s dusting and NE winds. Today’s sunny conditions and warmer temps may loosen small pockets of windblown snow and a film of rime ice from cliff faces in extreme terrain. Scabs of old wind slab that have been disconnected from residing snowfields by eroding winds are also features to be on the lookout for. Surface conditions are extremely variable with a plethora of obstacles and your exposure to them remains the biggest hazard.
