It has been 5 days since our last loading event of 6-10” and 30+ mph winds. Surface snow instability has been our primary concern over the last week and we caution those getting into very steep terrain to be aware of the consequences should one find a small wind slab or trigger a sluff today.
Old wind slabs 2-10” thick, both soft and hard, could be lingering on steep and complex terrain. This type of hazard is unlikely to bury a person, but could take you for a ride over a steep cliff or rocky chute. It is in these locations where being aware of the consequences of a fall should be at the forefront of your mind. It is also important to mention that surface conditions are variable and it can be difficult to see the consistency of the snow changing from soft to breakable.
Isolated pockets of loose dry snow can be found in steep gullies and chutes. With such cold temperatures this snow could be fast moving and knock you off your feet if it gains momentum. With good sluff management skills this is a minor concern.
LOW avalanche danger does not mean NO danger. It is important to still practice safe travel protocols. Identify safe spots, move between islands of safety one at a time, and always have an escape zone in mind.
Frostbite is a legitimate concern today. As of this morning Sunburst Wx station has reached an all time season low of -8 F. Daytime highs will be near 0 F and winds are expected to be 10-20 mph from the Northwest; just cold enough to drop the wind chill to -20 F. Bring extra warm layers in order to minimize exposure to your extremities and your face. Stop to rewarm hands and feet as needed.
Surface conditions vary from breakable wind stiffened snow to protected pockets of powder.
Yesterday skies were clear and daytime temperatures remained in the single digits F, even in the sun. Overnight lows reached -6 to -8 F along ridgetops. Winds were light 5-15 mph from the West. No new precipitation fell in the last 24 hours.
Today expect more of the same; clear skies and cold temps. Daytime temperatures will be near 0 F and ridgetop winds will be 10-20 mph from the Northwest. Near Whittier and Seward winds are expected to increase to 30-40 mph.
Cold and dry weather will last through Saturday. A large Sourtherly flow is expected to arrive in Southcentral Alaska by Sunday bringing warmer temperatures and fingers crossed, a shot of SNOW!
