Forecast: Salt Lake Area Mountains - Utah Avalanche Center

Forecast for the Salt Lake Area Mountains

Issued by Drew Hardesty on
Thursday morning, January 13, 2022

Areas of MODERATE danger exist on mid and upper elevation aspects facing west to north and east where it is possible to trigger a large and dangerous avalanche that may break down 3-10' deep and up to hundreds of feet wide.

The danger for wet avalanches may also rise to MODERATE with direct sun and the excessive heat. Watch for small wet-loose avalanches in steep southerly-facing terrain and have an exit plan that allows you to quickly respond to wet snow activity.

Special Announcements

Grizzly Gulch will be closed until about 1300 hours today as Wasatch Backcountry Rescue conducts helicopter and avalanche dog rescue training operations.

Weather and Snow

It's the January Thaw. Alta reported temperatures reaching 47°F at their base area yesterday. That is not a type.

Sweltering temperatures continued through the night. Get this: 10 and 11,000' temperatures are in the low 40s now.

Skies are clear and winds are light from the southwest.

For today, we'll see warm air continue to stream into the state along with a bump in southwest winds. Temperatures will again reach into the 30s and 40s in the mountains.

Tonight's cold front will bring about immediate relief to the temperature regime in the mountains AND improve the air conditions in the valleys but it's a mostly dry cold front and we'll be lucky to see a trace of snow.

High pressure and warm temperatures quickly rebound for the weekend. And beyond.

Wind, sun, and rime crusts dominate the landscape, but soft settled recrystallized powder can be found in the protected northerly terrain. Travel is easy and while powder is scarce, the aesthetic in you can find good things in the mountains.

Description

There is a persistent weak layer (PWL) of old faceted snow near the ground with 3-10' of snow on top of it. This PWL exists on mid and upper elevation slopes facing west through north and east. It does not exist on south-facing slopes as any early season snow melted away and December snowfall landed on bare ground. The last avalanche into this old layering probably occurred on January 5th or 6th in the central Wasatch.

One party experienced a collapse in one of the Powder Parks of Mill D North of BCC yesterday. It's the first report of a collapse or shooting crack in quite some time. Snowpit tests and observations continue to produce inconsistent results but we do know that weak snow exists near the ground and we do know that many experienced people continue to avoid steep terrain. For now.

Description

This is probably overdone, but I want to put wet avalanches on your radar for today. We experienced a poor and superficial refreeze overnight and wet avalanches will be possible today with direct sun and the scalding heat.

Remember that wet avalanches and troublesome to get caught up in and set up like concrete. Don't overstay your welcome if the snow becomes wet and unsupportable.
