With the active weather the avalanche danger remains elevated. Snow at upper elevations and rain at lower elevations is expected to continue today. Rain/snow line is forecast to be around 2500′. Winds are forecast to be easterly with gusts into the 40s. Our road observations yesterday had limited visibility but a few wet loose avalanches were observed to have run in the mid-elevation band. Rain continues to wash away the snow that fell on Saturday night in this elevation band.
Water totals at the mid-elevation snow stations for this soggy storm cycle:
If we convert the water to snow at upper elevations we have a significant load. We are uncertain at this point about avalanche activity in the Alpine. However snow continues to fall, the winds are sustained and we know this is loading older layers of snow. With this recipe we have to expect storm slab avalanches.

Yesterday: Rain and snow throughout the day. Rain/snowline was around 2500′. Temperatures were in the high to mid 30Fs at lower elevations and low 30Fs to high 20Fs at upper elevations. Winds were easterly 15-25 mph with gusts into the 40s.
Today: As a low in the Gulf continues to push moisture and warm air into the region rain and snow showers will continue. Half to three quarters of an inch of water is forecast to fall. Rain/snowline will remain around 2500′ before lowering Wednesday as cooler air moves in. Winds will be from the E-SE 20-30 mph with gusts into the 40s. Temperatures will be in the 40Fs to high 20Fs depending on elevation.
Tomorrow: A trough bringing cooler air is forecast to push up Cook Inlet with the potential to bring snow to Anchorage and Hatcher Pass. The advisory area should see a shift to snow showers with cooling temperatures later in the day into Thursday. The timing on all this is fairly uncertain as the weather models are not in agreement.
