Salt Lake Avalanche Advisory

Forecaster: Brett Kobernik

SPECIAL ANNOUNCEMENT

This will be our last week of morning forecasts. After Easter Sunday, we will do intermittent afternoon updates until near the end of April or conditions become very benign, whichever comes first.


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

The avalanche danger today starts out LOW and may rise to MODERATE with daytime heating. Get off slopes that become wet and punchy from daytime heating. East aspects get heated first, then south then west.


CURRENT CONDITIONS

Temperatures overnight were around freezing or a bit warmer up into the mid 30s. With mostly clear skies, this should produce an “ok” refreeze of the snow surface. Southerly winds are blowing a bit with strong gusts along the higher locations and moderate to strong gusts in the mid elevation ridges. A decent refreeze on Tuesday night provided nice riding conditions on Wednesday with the proper timing of aspect choice. This could be the same today.


RECENT ACTIVITY

We received a report of a small natural wet slab avalanche that happened on the 2nd or 3rd in one of the Monitors in a shallow snowpack location. Drew went up to the Ogden mountains to look at a recent slide and found damp surface hoar as the weak layer. DETAILS Another party came across an avalanche in Mill B South (photo below) which most likely released with last week’s heating. DETAILS


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 10 hours.

Heat related avalanche activity is your main concern today. I don’t think we’ll see a significant natural cycle today but it’s still best to exit the mountains as the snow surface starts to become punchy. Avoid the bottoms of avalanche paths and terrain traps like gullies on your exit. Steep, rocky terrain with shallow snow depths are the most likely locations for natural wet slab avalanches.


MOUNTAIN WEATHER

We’ll have gusty south winds with temperatures into the mid 40s at 8000 feet and 30s along the higher ridges. A few clouds will roll through and increase this afternoon. A cold front will move through tonight and produce some snow which should linger into Friday. This looks like another small storm which might produce 2 to 4 inches in most locations with the upper ends of the Cottonwoods possibly doing a bit better. We go right back to high pressure and warm temperatures through the weekend and into the middle of next week.


GENERAL ANNOUNCEMENTS

If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
