November 7 UPDATE
Avalanche Danger is Expected to Rise

The first potent winter storm of 2023/24 looks to hit Wednesday, Nov 8th. HEADS UP!

Large avalanches should begin to release on their own as the storm peaks Wednesday. In the following days, it’s hard to know how quickly the new snow will stabilize, so keep your guard up in case it’s still easy to trigger an avalanche. Avy season is starting…

Anywhere from 2-4+ feet of new heavy dense snow is expected to fall between Tuesday night and Thursday morning along with strong east winds. The rain/snow line is expected around 1,000′ and rising as high as 2,500′ in places near Portage Valley by Wednesday afternoon. Snow should start to pile up and begin to avalanche at elevations above 1,500′, yet debris could funnel down avalanche paths all the way to sea level where it’s likely to be raining.

In short, Wednesday’s a good day to avoid the mountains unless you know for sure your route doesn’t go into, or underneath, any type of avalanche terrain. Once the skies clear post storm it will be important to look for Red Flags (recent avalanches, whumpfing or collapsing in the snow, or cracks that shoot out from you). As the adage goes, “if there is enough snow to ride, there is enough to slide”. We can’t let the early season thin snowpack fool us.

 

Precipitation graphic produced by the NWS. Note the inches are in water equivalent, which means roughly 1″ of precip = 10-12″ of snow where it’s snowing and simply rain amounts where it’s raining.

The snow cover currently consists of 3-6″ inches of fluff from Sunday’s light snow event sitting on either bare ground below ~2,500′ or sitting on a foot or so of older snow at the higher elevations.

Crow Pass during Sunday’s new 4-6″ of snow. Thanks to Brandon McNaughton for passing along his report! 11.05.23
