HP’s weak snowpack will persist for a very long time. Pay attention to weather changes as our snowpack will not like rapid change. Each time our snowpack is rapidly loaded with new snow, or wind transported snow, expect the avalanche hazard to rise. Each time the weather becomes mild and boring, expect the snowpack’s stability to slowly increase.
This weekend the forecast is calling for light winds and cool temps. This kind of weather will not increase the avalanche hazard. However, pay close attention to the winds. For Sunday and into Monday, models are suggesting a slight increase in the pressure differential between mainland Alaska and the Southcentral coastline. This is not predicted to increase winds speeds over the next couple days. However, if the pressure differential were to build beyond the forecast, strong, outflow winds could increase in the avalanche hazard.
Today a MODERATE avalanche hazard for persistent slab and loose dry avalanches exists. Human triggered avalanches are possible and natural avalanches are unlikely.
Slab avalanches are the main concern, up to 2-4 feet deep, and large enough to bury, injure, or kill a person.
We can not emphasize this enough, AVOID STEEP SLOPES WITH TERRAIN TRAPS; choose slopes with gentle, fanning runouts.
DONATE HERE, ’cause it takes a community to raise an avalanche center!
