Forecasters are relying on weather models predicting daytime warming which can vary widely. A cool day is expected on Tuesday but if you encounter warm temperatures default to conservative choices. Start your day exceptionally early.

Weather Forecast

A cloudy cool morning is expected Tuesday, with clearing in the after noon. Valley temps are going to be just above freeing in the warmest part of the day. Winds are expected to be light form the West. No precipitation to speak of.

Snowpack Summary

Dry low density snow remains preserved on Northerly aspects with a skiable temperature crust below 1700m. On solar aspects substantial surface crusts have formed. Extensive wind effect in the alpine with isolated sheltered areas. Recent profiles show the Feb. 19 and Jan. 27 facets in the upper meter with hard to no results.

Avalanche Summary

No avalanches were observed or reported on Monday.

Confidence

Freezing levels are uncertain on Tuesday

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
