 Persistent Slabs
|
Today, above 2500′ the danger is CONSIDERABLE where natural avalanches are possible and human triggered avalanches are likely. East winds persist and snow continues to accumulate above 3000′ creating wind slabs and growing cornices throughout the region. The persistent warm temperatures are making the snowpack thin up to 2500′. It’s a great day to tune [Read More] | ||

Another round of strong wind and several inches of new snow will keep the avalanche danger above 2,500′ CONSIDERABLE. Natural avalanches are possible, especially in the Portage Valley where the majority of precipitation is expected. Human triggered wind slab avalanches and cornice falls are likely region-wide as winds continue to load high elevation leeward slopes. [Read More] | ||
 Storm Slabs
|
Persistent Slabs
|
The avalanche danger above 2500′ is CONSIDERABLE. Human triggered avalanches are likely and naturals are still possible. The Alpine received heavy snow with strong winds yesterday and the snowpack needs time to adjust. Below 2500′ where most of the precipitation fell as rain the danger is MODERATE. There is no snow below 1000′ and NO [Read More] | ||

Due to strong winds, heavy snow and rain the avalanche danger is HIGH at all elevation bands. Natural avalanches are likely. Travel in avalanche terrain is not recommended. This includes low elevation terrain that is in the runout of slopes above. *Today is not the day to hike Byron Glacier trail. [Read More] | ||

Persistent Slabs
|
The avalanche danger remains CONSIDERABLE above 2,500′ in the Alpine. Slab avalanches, between 8 inches to 2 feet thick and composed of yesterday’s new snow, are likely to be triggered on upper elevation slopes. Additionally, newly formed cornices may break off easily. New snow amounts vary and areas with little new snow have a MODERATE [Read More] | ||

Persistent Slabs
|
The avalanche danger will rise to CONSIDERABLE above 1,000′ today as a warm storm brings up to a foot of new snow with strong ridgetop winds. Another 5-8″ of snow is expected tonight. Natural avalanches composed of the new snow are possible, such as wind slabs, storm slabs and cornice falls, and human triggered avalanches [Read More] | ||

|
The avalanche danger remains MODERATE in the Alpine due to a buried layer of faceted snow that sits 2-3′ below the snow surface. This layer is still showing signs that an avalanche could be triggered on steep slopes at the high elevations above 3,000′. Below 3,000′ there is a LOW avalanche danger. *Avalanche danger expected [Read More] | ||

A MODERATE avalanche danger exists above 2,500′. Triggering a large, dangerous avalanche remains possible due to a suspect weak layer/ bed surface combination near the ground. In addition, be on the lookout for lingering small wind slabs particularly along or just below leeward ridges. [Read More] | ||

A CONSIDERABLE avalanche danger remains at the higher elevations above treeline. Storm snow avalanches, including wind slabs, are likely to be triggered on slopes over 30 degrees. Additionally, triggering a surprisingly larger, and dangerous, slab avalanche is possible that breaks in old weak snow 1-3+ feet below the snow surface. Heads up once the skies [Read More] | ||

The avalanche danger is CONSIDERABLE at all elevation bands. In the Alpine and Treeline triggering a slab avalanche is likely and natural avalanches are possible. Avalanches that release in higher elevation terrain could send debris into the lower elevation (below 1000′) runout. Cautious route-finding and conservative decision-making are essential.

It is starting to look like winter across the Turnagain Forecast area. Let’s do a quick snowfall recap to paint the picture of the season so far. A storm on 10/22-23 brought about 2′ of snow with snow line around 2000′ and strong winds. During the next storm on 10/27-28 it rained to 3500′ washing [Read More] | ||

Over the weekend a little snow actually made it to sea level. Girdwood had a few inches in town while Turnagain Pass at road level (1000′) only received a half an inch of snow. Upper elevations (above 2500′) received around a 1′ of snow. Late Friday night also brought stronger easterly winds with gusts into [Read More] | ||

Despite plenty of precipitation for November, winter at Turnagain Pass has yet to arrive. Storm systems have been scooping up warm sub-tropical air and bringing it north to our region. Rain has been falling up to the ridgetops at Turnagain with occasional cooler periods bringing snow to mid-mountain before warming back up again. Looking forward [Read More] | ||

We continue to watch the weather with hopes for a colder storm, #snowtosealevel. After a partly sunny Veterans Day the forecast for this week looks to have precipitation but not snow producing temps. Upper elevation terrain (above 4000′) received a little new snow this past week. Sunshine and warmer temperatures on Friday and Saturday caused [Read More] | ||

The avalanche danger remains MODERATE at all elevations. In the mid-elevations, glide avalanches continue to release sporadically and are creating a dangerous and unpredictable hazard. Limit any travel under glide cracks. Additionally, wet loose sluffs are possible on saturated steep slopes below 2,000′. In the Alpine, watch for areas with new wind-drifted snow where small [Read More] | ||
