Points saillants

Today the avalanche danger is CONSIDERABLE at upper elevations where dangerous avalanche conditions exist. Triggering a monster avalanche will not be likely, but deadly consequences make the situation dangerous. Triggering one of these slides is possible but less likely at mid elevations where the danger is MODERATE.

The danger is MODERATE at low elevations where wet avalanches are possible especially on southerly facing and west facing slopes.

    Avalanches breaking on persistent weak layers buried deep in the snowpack are a challenging avalanche problem to assess. Knowing the likelihood that a human can trigger one is really tough. It has been 5 days since the storm ended that caused a widespread natural avalanche cycle. Because these layers are buried so deeply, it will be tough to trigger an avalanche like ones that occurred just after the storm; however, the consequences would be deadly.

    Personally, I would not be comfortable riding in avalanche terrain feet until significant time had passed since recent loading. How much time? Certainly more than 5 days. Another storm may arrive on Wednesday and could add additional weight and stress to the snowpack to raise the likelihood of triggering one of these slides.

    Most of these types of avalanches occurred above 11,000 feet. Noriega's Face is a notable exception.

    Watch for warming of the new snow today at low elevations. This morning is starting very cold but should warm rapidly as the strong March sun rises. The new snow has been through a couple of days of warming and re-freezing making loose wet avalanches less likely.

    You should see roller balls and pinwheels of snow rolling downhill. As this activity increases, the danger for loose wet avalanches increases. The simple strategy is to avoid being under steep slopes as the snow gets wet.

Special Announcement

The road to Geyser Pass Trailhead will closed today while crews finish plowing snow off the road.

Recent Activity

Following the storm on Tuesday/Wednesday there were many avalanches. Some broke within the new snow. However, many broke 1/4 to 1/2 mile wide at the ground. See the full list of avalanches we have cataloged so far HERE.

Snow and Weather

This morning under clear skies, temperatures dropped into the upper teens and low 20s F. Yesterday temperatures reached the low 40s F at low elevations and near 30 degrees above 11,000 feet.

Winds were calm yesterday but increased from the SW this morning and were blowing 14 mph gusting 17 mph on Abajo Peak.

Today, temperatures will rise again into the 40s F at lower elevations and 30s F at upper elevations. There will be a few clouds in the sky today and winds will generally blow from the SW at 5-10 mph with some gusts of 15 mph.

The snow on many slopes has been going through a melt-freeze cycle for the last three days.

Looking ahead, today and Tuesday will have sunny skies. More precipitation arrives late Wednesday. By Thursday morning there could be up to an inch of water and maybe a foot of snow.

Total snow depth in Gold Basin at 10,000 feet is 8 feet 7 inches.

New snow totals in Gold Basin (10,000')

Snotel totals at the Geyser Pass Trailhead (9600')

Winds at 11,000 feet on Abajo Peak (11,330') about 45 miles south.
