For the forecast, a weak warm front this morning will give us mostly overcast skies with the chance of some very light precipitation. The Freezing level is expected to gradually rise today and reach 2000+ meters by this evening. A very warm high pressure system from the South will bring unsettled conditions to our zone for Monday thru Tuesday with a mix of sun and cloud in a dry air mass. The FL will reach well above the local peaks (high as 3800 meters) for Monday into Tuesday.  An upper level low forms over the NE Pacific for Wednesday, a warm front will push into our zone in the morning with light precipitation and a FL of around 2000 meters which will gradually drop to 1700 meters by the evening. The remainder of the week looks warm and wet. Stay tuned for possible changes as the week progresses. Guesstimates: 1-3 cm by Monday morning.

Natural avalanches up to Sz 3 were observed in the Sea to Sky Corridor yesterday during the storm, avalanche control on WB did produce soft slabs with Xe and Sc yesterday morning, Sz 1-2.
