May see a shower around noon, but very isolated and unlikely. A cold front arrives around daybreak on Thursday with periods of light to moderate snow expected with strong winds and warmer temps. Could see the FL go up to 1500 meters but more on that as we get closer. You get the picture-wet, warm & windy. Low will make landfall and bring more precip with a lowering FL on Friday. Dries out by Saturday with unsettled weather. Guesstimates: 0-trace by Wednesday am, 0-trace by Thursday am, 30-40 cm above 1500 meters by Friday an, 20-25 cm by Saturday am.
AVALANCHE ACTIVITY:
No new avalanches observed on Blackcomb.From Sea to Sky avalanche advisory:
Avalanche Summary
No new reports since Saturday when natural and human triggered avalanche activity quieted down but cornices continued to be reactive to explosives size 2-2.5. Minor pinwheeling was observed on steep solar aspects in the afternoon.
Snowpack Summary
20 cm of recent snow overlies a variety of old surfaces including facets, spotty surface hoar in wind sheltered areas around treeline, a sun crust on steep solar aspects and a rain crust below 1500 m. Recent wind of varying direction has blown this snow into wind slabs on a variety of aspects.
A weak layer buried in mid-February is composed of a crust, facets or spotty surface hoar depending on elevation/aspect, and is now down 50-80 cm. There have been no recent avalanches reported on this layer. Large triggers, such as an avalanche in motion, cornice fall, or intense loading from snow, wind and/or a rapid rise in temperature could awaken these deeper weak layers.
The mid and lower snowpack is well settled and strong in most areas.
