Recent Weather Summary (Chart):

Onshore flow with light precipitation and lots of clouds will remain through the weekend. Rain/snow will increase on Saturday-Sunday and become occasionally heavy, with snow levels remaining near 2000ft.

The 26th brought around 0.50" of precipitation with snow levels near 2000ft and gusty south winds.

The 21st brought around 12" of new snow over the mountains, with snow levels near 2000ft and moderate south winds.

Snow totals from the 12th-13th include 25" of snow (1.51" SWE) at Customs, and 15" of snow (1.65" SWE) in town. General snow totals of 2-3 feet fell over the mountains. Winds were strong and variable.

Lutak Zone (see map)

Danger: Considerable See Scale
Alpine temperatures are not expected to reach above freezing today, but solar radiation is hitting south aspects hard during the day, which can lead to a variety of concerns. Mainly: icy debris and point-release avalanches coming down naturally from steep slopes.

In areas that are wind loaded by recent south winds, human triggered avalanches are likely on density interfaces within the new snow. Be wary of north aspects below ridgelines, and gullies which may be cross-loaded. Avalanches could be quite deep in heavily wind loaded pockets.

Keep your guard up, practice safe travel technique, and always carry a beacon, shovel, and probe.

Transitional Zone (see map)

Danger: Considerable See Scale
Alpine conditions in this zone are similar to the Lutak zone. See above for more information.

Chilkat Pass Zone (see map)

Danger: Considerable See Scale
In addition to the recent storm snow concerns mentioned above...

As one progresses northward over the pass (or into the highest alpine slopes), the lower snowpack becomes heavily facetted. Depth hoar crystals up to 5mm in size dominate the lower snowpack beneath recent storm slabs. Whumphing has been reported on the facet layer over the last few weeks, and propagation of the collapsing was wide. Though things have settled down a little bit and triggering this layer is less likely, the consequences of triggering a slab this deep could be big. Consider this deep-slab danger carefully if you choose to travel in avalanche terrain. Surface avalanches may step down to this deep facet layer.
