Recent Weather Summary (Chart):

Around 1-1.5" of SWE is expected Thursday, adding up to over a foot of new snow over the mountains. Winds will be variable and gusty. Light snowfall Friday may intensify again Friday night.

January 25th-28th brought around 3.7" of precipitation at Customs, and around 5.1" in Haines. Totals over the mountains were likely between 6 and 8+" of liquid equivalent. Snow levels averaged about 1000ft during this time, and peaked around 2000ft. Strong south winds predominated during the last half of the storm cycle.

About 30-45" of new snow fell over the mountains from January 17th-24th. Temperatures were rising through the week.

About 12" of new snow fell over the mountains January 11th.

About 6" fell over the mountains Jan. 8-10th.

December 28th-30th brought 1.5-2.5" of precipitation over the mountains. This added up to 1-2 feet of new dense snow. South winds were strong.

Lutak Zone (see map)

Danger: Considerable See Scale
Thursday's heavy snowfall has built fresh storm slabs which still need time to settle. In many places above treeline, there are hard wind slabs (and rain crusts below treeline) beneath the new snow, making a good bed surface for the new snow to slide on. Expect the new snow to be moving around on any steep aspects. Any wind loaded slopes may have deep and dangerous storm slabs and should be avoided.

Wind slabs that built towards the end of last week's storm cycle are still active in recent snowpits, with Q1 shears reported on various crusts/slabs in the mid pack. Especially with the new loading from Thursday's storm, some slides could fail on these layers 30-60cm deep.

Careful terrain selection is key right now. Give any steep avalanche terrain a wide berth, as remote triggering is possible. Your weight can trigger a whumpf (collapse) in low-angle terrain, and the collapse may propagate uphill and trigger an avalanche on slopes above you.

Please send in any snow or weather observations. Whumphs, shooting cracks, and slab avalanche activity is especially important to report.

In windswept alpine areas, or anywhere with a thin snowpack less than a meter deep, significant basal facets/depth hoar exist near the ground. Several natural slides from the last week ran down to the ground on this layer. Avoid thin areas which will be likely trigger points for deep avalanches.
