Until this next round of storms moves in tonight, avalanche issues will continue to be lingering wind slabs in exposed areas and sluffs in steep terrain. In the higher elevations, the 1.5 – 2.5 feet of new snow from Sunday night has been hit by winds from the northwest, to south, to east. If getting into zones above treeline, be sure to feel for stiff snow over softer snow and watch for any cracking or collapsing. Slabs could be anywhere from a foot to several feet thick and could be on the more difficult side to trigger.
In sheltered areas away of any wind effect, the new snow is slowly settling and bonding, but still quite soft. If getting onto the steeper slopes, even short steep slopes in the trees, sluffs could be triggered if the slope is steep enough. Tree wells are also getting larger and something to keep in our minds. A good reminder to always keep an eye on our partners.
The big news is the storm system that should bring some light snow showers this afternoon, then more snow and wind late tonight into tomorrow morning. This event looks to favor the Anchorage area and Hatcher Pass regions while here in Girdwood and Turnagain Pass we are looking at 6-8″, maybe up to 12″ if we’re lucky. It will be a warmer storm and a rain/snow mix may be seen in Girdwood. Stay tuned for tomorrow’s forecast and be sure to check hpavalacnhe.org for Hatcher Pass’s Thursday morning forecast!
Yesterday: Overcast skies with a few sucker holes midday. Light snow flurries added 1-4″ of new snow with little water weight. Winds were light from the southeast (5-10mph) along ridgetops and temperatures were in the teens to 20’s.
Today: Another system is headed in that will bring light snow during the afternoon and peak tonight. Around 1-3″ is expected this afternoon with another 3-6+” overnight. Temperatures are warming and we could see the rain/snow line rise to 500′ or so briefly tonight before cooling back off tomorrow morning. Ridgetop winds will be light and variable until they pick up tonight into the 30’s mph from the SE.
Tomorrow: Skies should start clearing and temperatures drop as precipitation ends tomorrow morning. Ridgetop winds will be shifting to the NW and expected to blow in the 10-20mph range. Mostly clear and quiet weather is expected Friday through the weekend.
