South Coast.
Cooling temperatures will make avalanches less likely, but the resulting surface crust will make for difficult travel conditions.
MONDAY NIGHT: Clear skies, light northwest wind, freezing level climbs to 2000 m, treeline temperatures reach +3 C.
TUESDAY: Clear skies in the morning with light wind and freezing level around 1300 m, then temperatures drop in the afternoon with freezing level down to 800 m, increasing cloud, light snow flurries, and moderate west wind.
WEDNESDAY: Mostly cloudy, light variable ridgetop wind, freezing level around 700 m with treeline temperatures around -2 C.
THURSDAY: Cloudy with some light flurries, light wind, freezing level drops to 500 m with treeline temperatures around -2 C.
Some small wet loose avalanches were reported as temperatures spiked on Sunday, however this problem will diminish with cooling temperatures on Tuesday.
Wet surfaces will freeze as temperatures cool on Tuesday and form a widespread surface crust. The exception may be higher elevation north-facing slopes, where there could be roughly 10 cm of snow sitting above crusts. There could be some weak faceted snow forming around these crusts, but avalanches on this layer are unlikely at this point. The lower snowpack is a well consolidated multi-tiered sandwich of crusts and moist snow.
