Waterton has transitioned to spring conditions. Spring snowstorms are still possible however wet loose avalanches are the primary concern.

Plan to be finished early before the hottest part of the day. Some eastern parts of the park are nearly free of snow.

Confidence

Moderate

Avalanche Summary

A natural loose wet cycle to size 2 was observed over the weekend.

Snowpack Summary

Very warm daytime temps and limited overnight refreezes will keep the snowpack isothermal on all aspects at all elevations. 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.

Weather Summary

Tues-Thurs

Temps are forecast to continue to be unseasonably hot over the next three days. Alpine highs in the +20's are possible. Winds will be light to moderate from the SW and skies will be mostly clear.
