Weather Forecast

There will be light snow flurries in the higher elevations with occasional showers in the valley bottom through to mid week. Temperatures are expected to remain cool with light Northerly winds. Sunny periods are expected later in the week before returning to overcast skies and precipitation.

Snowpack Summary

A spring snowpack now exists in the forecast area. Clear nights with below freezing temperatures will make a supportive snowpack and good travel conditions. If no freeze occurs, it will become isothermal and melt quickly. Northerly aspects may still retain some deeper instabilities that could produce large slab avalanches during warm weather.

Avalanche Summary

Redistributed storm snow may produce avalanches to size 2 on lee aspects and lee terrain features. Northerly aspects in the alpine have lingering deep snow instabilities that may produce larger avalanches later in the season. Warmer weather will result in loose snow avalanches from steeper terrain on warm, sunny days.
