The Bottom Line
2018/2019 winter avalanche season has begun!
Wednesday Nov. 7th update:
Winter is here and the snowpack is slowly forming in the mountains surrounding Girdwood and Turnagain Pass. Tonight a small storm may bring up to 6-8″ of new snow to higher elevations. Temperatures have started to increase into the mid 30F’s near sea level and East winds are expected to be moderate (15-30mph) overnight. This new snow will be landing on a shallow snowpack, roughly 8-10″ of settled snow below 2500.’ Cold temperatures over the last 10 days have formed weak faceted snow and surface hoar. Avalanche activity over the next few days will depend on how much new snow we get and how this new snow bonds to the current surfaces. Above 2500′ there is more of a layered snowpack where rain from mid-October fell as snow in the Alpine. We have already seen a few human triggered avalanches in the Alpine which are good reminders that a thin snowpack can still produce a slide. Here’s a recap of these recent avalanche observations:
- Oct. 30th, we received our first report of a small remote triggered avalanche along the Crow Pass Trail.
- Oct. 31st, avalanche triggered by a skier taking a few jumps on the snow at the entrance to a line off of Pastoral Peak. This avalanche was up to 2′ deep yet only 20′ wide.
- Nov 3rd, another avalanche on Pastoral Peak, triggered intentionally by a skier performing a ski cut. This was a shallow wind slab, 3-8″ thick, 30′ wide and running full path.
Remember to always consider the consequences of an avalanche, even a small wind slab can knock a person off their feet and somewhere they don’t want to go. If you head out into the mountains be on the look out for Red Flag warnings:
- Recent avalanches
- Cracks in the snow that shoot out from you
- Whumpfing (collapsing) of the snowpack
- Rapid changes in weather (snow/rain/wind/temperature)
Both surface hoar and faceting old snow have been observed this week in Turnagain Pass. These could be our first persistent weak layers if we get any new snow this week.
A thin sun crust was found on steep southerly aspects on Seattle Ridge as well as a thin early season snowpack.
A human triggered wind slab on a North aspect of Pastoral that was triggered on 11/4 due to moderate winds the two days prior.
Moderate NW winds blowing snow around on Nov.2 on Sunburst
Special AnnouncementsThe CNFAIC will be issuing intermittent snow and avalanche updates as conditions warrant through mid-November. Daily avalanche forecasts are planned to begin on Thanksgiving weekend – unless we see more snow and avalanche issues before this demanding an earlier start.
