Hazard will be increased with daytime warming, pay special attention to solar slopes especially if the sky clears.

Travel may be very difficult in the afternoon as snowpack transitions to isothermal.

Earlier this week a small wet loose cycle occurred in the new surface snow. Avalanches to size 2 were observed on all aspects.

Warm daytime temps and strong overnight refreezes have formed a surface crust complex on all aspects at all elevations. In the afternoon expect snow to turn isothermal. The January melt freeze crust is buried up to 100cm. Alpine and Treeline midpack is well settled and overlies basal facets and depth hoar. Most places the snowpack is now moist to ground.

Tues-Thurs

Temps continue to rise over the next three days. Alpine temps near +5 are possible with broken skies. Some convective flurries are possible over the next couple days before the larger high-pressure ridge sets up on the weekend. Winds will be moderate SW.

• Avoid steep slopes when air temperatures are warm, or solar radiation is strong.
