Summary

Confidence

Fair - Timing, track, or intensity of incoming weather system is uncertain

Weather Forecast

Overnight and Tuesday: The inversion is forecast to slowly break down tonight allowing some Pacific moisture to move into the region starting at higher elevations and then filling in to lower elevations. Expect very light precipitation falling as snow in the alpine overnight. A mix of snow and rain during the day Tuesday as the cloud moves to the East and freezing levels drop down to about 1000 metres. Winds are expected to be moderate from the Southwest.Wednesday: Moderate precipitation 5-15 cm above about 800 metres elevation. Continued moderate Southwest winds.Thursday: Light precipitation 3-5 cm as the weak system exits the region. Light to moderate West-Northwest winds.

Avalanche Summary

Some loose wet avalanches were reported. This problem should end with forecast cooling and cloud.

Snowpack Summary

Expect good crust recovery overnight as the temperature inversion breaks down and freezing levels begin to drop. New snow may bury surface hoar that has grown at and below treeline over the past few days. In the alpine new snow may not bond to the old surface depending on the timing of the cooling. Deeply buried weak layers continue to exist, however the bridging effect of the re-frozen upper snowpack may reduce the likelihood of triggering.
