12th Annual Utah Snow & Avalanche Workshop Open and Motorized Sessions November 2.

Forecast for the Salt Lake Area Mountains

Issued by Mark Staples for Sunday, October 20, 2019 - 7:26am
SUNDAY MORNING, OCTOBER 20TH
Very strong winds and heavy snowfall occurred overnight. This is a very good recipe for avalanches. Winds have been drifting snow even at low elevations. Many slabs of wind drifted snow exist and could probably be triggered today.
Some snow fell in early September, but these two storms (Oct 17 & 19) have brought the first major snow of the season. This recent snow will likely form the foundation for the snowpack at least on northerly aspects where it won't melt in coming weeks. This snow and subsequent snow will change a lot and potentially set the stage for avalanche conditions later this winter. We will be watching it closely.

If you go out, there are a few things to remember:
  1. Hitting rocks and stumps is a real danger. Don't end your season before it starts with an injury from hitting one of these obstacles.
  2. Avalanches are a real possibility. It doesn't matter if you are hiking, hunting, skiing, etc., be prepared with rescue gear and a partner. Many people have died during early season snow storms. Listen to this podcast episode about a bad day in November 2011 when many avalanches were triggered and pro skier Jamie Pierre died.
  3. Ski resorts all have different uphill travel policies. Some are closed, like Snowbird, others are open. These closed resorts can be great places to get in a little skiing especially in you know of a rock free slope, but it should be treated as backcountry terrain. More info HERE but check with each resort for the latest info.
