Highlights

A pockety MODERATE avalanche danger exists on some steep west to north to easterly facing slopes in the mid and upper elevations for triggering a 12-18" thick slab that fails on our old early season facets. Exercise caution in this terrain. The danger for wet avalanches will rise to MODERATE on many slopes today. Wet sluffs and possibly wet slabs will be likely in the coming days.

A persistent weak layer (PWL) of early season facets makes up the base of the snowpack on west-north-easterly facing slopes at the mid and upper elevations.In these areas, it is still possible to trigger an avalanche up to about 18 inches deep and over 100 feet wide. Cracking and collapsing are become less common and snow tests hint at slow stabilization, yet persistent weak layers come by their name honestly. Exercise caution if you're traveling through steep terrain with this poor structure.

Wet sluffs and wet slab avalanches will start to become a problem today through early next week. I've always felt uncomfortable forecasting wet avalanches and feel even less comfortable forecasting wet avalanches in mid-December. My recommendation - to keep it simple - is to pull the calendar off the wall and just observe what you're seeing and note how it feels under your feet. If you're seeing wet rollerballs and loose point releases and/or the snow starts to feel punchy and unconsolidated, head for a different aspect or low angle terrain. Remember that wet loose debris can pile up deeply in terrain traps.

Recent Activity

There were no new avalanches reported from the backcountry or the ski area yesterday. The Provo mountains did, however, experience a widespread avalanche cycle over the weekend, just in lockstep with the storm. UDOT Provo canyon avalanche workers spotted numerous large natural avalanches from the avalanche cycle (perhaps 1-2 feet deep but up to 1500 feet wide) in the upper reaches of the Cascade ridgeline and on Timpanogos.

Snow and Weather

Skies are clear.

Winds are moderate from the west.

Mountain temperatures look more like spring and not mid-December. Some mountain stations reached into the mid-40s yesterday and it's only going to get warmer in the coming days. It should be pointed out that some weather stations in the mid and low elevations have not had a proper refreeze for a day or two. See Timp Divide below.

For today, we'll see sunny skies, moderate winds from the west, and mountain temps rising to the upper 30s up high and the low-50s down low.

For the longer range, it looks as if the ridge of high pressure gets squashed down mid-next week, allowing for a somewhat more active weather pattern from the west. I continue to eye the Solstice for a glimmer of hope.

This morning, you'll be skiing and riding coral and breakable crust until things soften with daytime heating. The highest elevations do host a sliver of dry -albeit wind damaged - snow.
