 Persistent Slabs
|
The avalanche danger is CONSIDERABLE at all elevations where heavy precipitation is falling. This is in Portage and Placer Valleys and possibly in Girdwood. Turnagain Pass should see less precipitation and [Read More] | ||

Wind Slabs
|
Persistent Slabs
|
The avalanche danger is MODERATE at all elevations, and there is a variety of concerns. Strong easterly winds are expected to continue to form reactive wind slabs up to a foot deep [Read More] | ||

Wind Slabs
|
Persistent Slabs
|
The avalanche danger is MODERATE above 1000′. A frontal system is expected to head our way today, bringing strong easterly winds and light precipitation later in the day. Be on the [Read More] | ||

Wind Slabs
|
Persistent Slabs
|
The avalanche danger is MODERATE at all elevations today. Fresh wind slabs 6-12″ deep that formed overnight are likely for human triggering at upper elevations along ridgelines. Triggering a larger avalanche on [Read More] | ||
 Wet Loose
|
Persistent Slabs
|
Avalanche danger is expected to rise to CONSIDERABLE by this afternoon and evening with daytime warming. Wet snow avalanches are likely to occur in the mid and lower elevations on [Read More] | ||

Wet Loose
|
Persistent Slabs
|
The avalanche danger is MODERATE at all elevations. By this afternoon, daytime warming may be enough to melt surface crusts and cause natural wet loose avalanches on steep southerly slopes. [Read More] | ||

Wet Loose
|
Persistent Slabs
|
The avalanche danger will start out MODERATE and rise to CONSIDERABLE in the afternoon, as the sun and warm temperatures melt the snow surface. Natural wet loose avalanches are likely on steep [Read More] | ||

Wind Slabs
|
The avalanche danger is MODERATE at all elevations, and there are several avalanche concerns today. The biggest issue is the lingering possibility of triggering a large avalanche on a weak layer of [Read More] | ||

Wind Slabs
|
Persistent Slabs
|
The danger is CONSIDERABLE above 1000′. The most likely avalanches you will encounter today will be up to a foot deep on wind-loaded slopes. These will be easy to trigger and may [Read More] | ||
|
Wind Slabs
|
Persistent Slabs
|
The avalanche danger remains CONSIDERABLE above 1000′. The potential to trigger a large avalanche on a buried weak layer 2-5′ deep still exists. Smaller avalanches in wind loaded areas about 1′ deep [Read More] | ||
 Storm Slabs
|
Persistent Slabs
|
The avalanche danger remains CONSIDERABLE above 1000′. Many human triggered avalanches 1-3′ deep occurred yesterday, which is the number one sign of dangerous conditions. Today human triggered avalanches up to [Read More] | ||
|
Storm Slabs
|
Wet Loose
|
Dangerous avalanche conditions exist. Today is the first sunny day after a storm that deposited 3 to 5 feet of snow in 2 1/2 days. The avalanche danger is CONSIDERABLE [Read More] | ||
|
Storm Slabs
|
|
The avalanche danger remains HIGH in the alpine today. Human triggered avalanches are very likely as over 2.5′ of new snow has fallen in the past 2 days accompanied by [Read More] | ||
|
Storm Slabs
|
|
The avalanche danger is HIGH at all elevations today. Travel in avalanche terrain is not recommended. With 1.5′-2′ of new snow on the ground, 1′-2′ more new snow expected today [Read More] | ||
|
Wind Slabs
|
|
The avalanche danger is on the rise today, and will be CONSIDERABLE above 2500′. Another round of snow combined with increasing easterly winds will make it easy to trigger a wind slab [Read More] | ||
|
Wind Slabs
|
|
The avalanche danger is MODERATE at all elevations. 2-4″ new snow with light easterly winds will form small but sensitive slabs on wind loaded slopes. This round of snow is falling on [Read More] | ||
|
Persistent Slabs
|
Wet Loose
|
The avalanche danger is MODERATE at all elevations today. Human triggered avalanches are still possible on a weak layer of facets buried by 1-2′ of new snow on Tuesday night. We recommend [Read More] | ||
|
Storm Slabs
|
|
The avalanche danger is MODERATE at all elevations. Tuesday’s new snow has not entirely bonded yet and there is still a chance of triggering a slab avalanche between 1 to [Read More] | ||
|
Storm Slabs
|
Wet Loose
|
The avalanche danger is MODERATE at all elevations. Human triggered and natural avalanches 1-2′ deep in areas with active wind loading at upper elevations are the biggest concern. It is also still [Read More] | ||
|
Storm Slabs
|
|
The avalanche danger is CONSIDERABLE above 2500′. Overnight 6-10″ of new snow fell with moderate east winds. This rapid addition of new snow and wind will make human triggered avalanches likely today. [Read More] | ||
|
Wind Slabs
|
|
The avalanche danger is MODERATE above 1000’. Strong winds are expected to accompany 3 to 8” new snow by this afternoon, increasing the chances of triggering wind slab avalanches up [Read More] | ||
|
Wind Slabs
|
|
The avalanche danger is expected to rise to MODERATE in the higher elevations (above 2,500′) as easterly winds increase today. Wind slabs, up to a foot deep, are expected to [Read More] | ||
 Normal Caution
|
|
The avalanche danger is LOW today at all elevations. With another day of quiet weather and a generally stable snowpack in our core advisory area, it is unlikely, but not impossible, that [Read More] | ||
|
Wind Slabs
|
|
The avalanche danger is MODERATE above 2500′. Lingering wind slabs up to 1′ deep from the past several days of NW winds remain possible for human triggering today. These are most likely [Read More] | ||
|
Wind Slabs
|
|
The avalanche danger is MODERATE above 1000′. The NW winds over the past 3 days have formed wind slabs 1-2′ deep in exposed areas which will be possible for a person to [Read More] |
