The avalanche danger will start out LOW and rise to CONSIDERABLE as the snowpack heats up and wet snow avalanches become more likely. This includes wet loose, wet slab, and glide avalanches. Be aware of increasing danger as surface crusts break down and the snowpack becomes unsupportable. If you notice wet and sloppy snow on the surface, head to [Read More]

The avalanche danger will start off LOW and rise to CONSIDERABLE at all elevations today. Wet avalanches releasing as a slab several feet deep are the biggest concern. As the sun starts to heat up the snow surface wet avalanches will become more likely. To avoid being involved with a wet avalanche it is important to monitor [Read More]

The avalanche danger will start out LOW  but quickly rise to CONSIDERABLE as temperatures heat up and the chances for wet snow avalanches increase. The most likely avalanches to encounter will be wet loose avalanches, but we will also likely see continued glide and wet slab activity. All of these avalanches can be large and destructive, so it [Read More]

The avalanche danger is CONSIDERABLE at all elevations today. Wet avalanches are likely due to the warm temperatures and cloud cover over the past several days. Wet loose avalanches will be very easy to trigger and can grow quite large when running down long slopes. Wet slab avalanches are also likely today, which are highly destructive and [Read More]

The avalanche danger is CONSIDERABLE at all elevations today. With four days of above freezing temperatures and continued warm weather with light rain possible up to 2000′ by this afternoon, the chances for large wet snow avalanches are increasing. These may be natural or human-triggered. Wet loose avalanches are likely, and the chances for wet slab avalanches [Read More]

The avalanche danger is CONSIDERABLE above 2500′. Strong winds yesterday formed fresh wind slabs 1-2′ deep that are still possible for a person to trigger today.

The avalanche danger is CONSIDERABLE above 1000′. More wind and snow is on the way today, and the snow from Tuesday’s storm may still be reactive as this next loading event begins.

Avalanche danger today is directly related to how much snow fell during yesterday’s storm. A CONSIDERABLE avalanche danger exists where over a foot of new snow fell (Girdwood and Portage Valleys). Areas that saw less than a foot of new snow have a MODERATE danger (Turnagain Pass). Expect a variety of new snow avalanche issues [Read More]

The avalanche danger will rise to CONSIDERABLE today above 1,000′ as a cold storm system moves through bringing strong easterly wind and heavy snow showers to sea level across our advisory areas. Natural wind slab avalanches will be possible and human triggered avalanches up to 1′ deep will be likely. MODERATE danger exists below treeline [Read More]

The avalanche danger will start out LOW and rise to MODERATE as snow surfaces heat up through the day. Wet loose avalanches will be the main concern, starting with steep south-facing slopes. Be on the lookout for roller balls as an earlier indicator of increasing danger, and avoid traveling on or under steep slopes as temperatures rise this afternoon. [Read More]

The avalanche danger is MODERATE today. It is possible to trigger a wind slab avalanche around 6 to 12″ deep on upper-elevation slopes that were loaded last night.

The avalanche danger is MODERATE at all elevations. Watch for lingering wind slabs from yesterday’s northwesterly winds as well as new small wind slabs that could form later today as east winds increase.

The avalanche danger is MODERATE at all elevations today. Wind slabs 6-12″ thick are likely at upper elevations due to moderate winds from the west.

The avalanche danger remains CONSIDERABLE above 1000′. There were four large human-triggered avalanches yesterday, all failing at the interface between this week’s snow and an older crust.
