Date	Problem #1	Problem #2	The Bottom Line
Fri, March 29th, 2024	Wind Slabs	Wet Loose	The avalanche danger is CONSIDERABLE above 2500′. Fresh wind slabs up to 12″ deep will be forming today as a storm system impacts the forecast area with 2-8″ of new snow and [Read More]
Thu, March 28th, 2024	Wet Loose		Today’s avalanche danger is MODERATE. Calm winds, mild temperatures, and the potential for some sun along with another night of little to no refreeze will make wet snow avalanches possible. [Read More]
Wed, March 27th, 2024	Wet Loose		The avalanche danger is MODERATE at all elevations. Below 2,000′ warmer temperatures will make it easy to trigger a wet snow avalanche on steep slopes. There is also a small [Read More]
Tue, March 26th, 2024	Wind Slabs	Persistent Slabs	The avalanche danger is MODERATE at all elevations. A variety of avalanche concerns exist as warm weather remains over the region. Fresh wind slab avalanches could be found and triggered [Read More]
Mon, March 25th, 2024	Wind Slabs	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]
Sun, March 24th, 2024	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]
Sat, March 23rd, 2024	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]
Fri, March 22nd, 2024	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]
Thu, March 21st, 2024	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]
Wed, March 20th, 2024	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]
Tue, March 19th, 2024	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]
Mon, March 18th, 2024	Persistent Slabs	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]
Sun, March 17th, 2024	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]
Sat, March 16th, 2024	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]
Fri, March 15th, 2024	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]
Thu, March 14th, 2024	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]
Wed, March 13th, 2024	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]
Tue, March 12th, 2024	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]
Mon, March 11th, 2024	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]
Sun, March 10th, 2024	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]
Sat, March 9th, 2024	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]
Fri, March 8th, 2024	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]
Thu, March 7th, 2024	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]
Wed, March 6th, 2024	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]
Tue, March 5th, 2024	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]
