South Coast

Fresh & reactive storm slabs are forming above the snow/rain line at upper elevations.

Stick to simple terrain and avoid overhead hazard.

No new avalanches were reported aside from some minor sluffing during periods of heavy rain on Sunday. See photo below for the most recent slab avalanche activity.

Forecast snow and wind are expected to form reactive storm slabs at upper elevations.

30 to 60 cm is forecast to fall above 1200 m overnight and through Tuesday, however freezing levels are uncertain, and it's possible it will rain higher. The new snow is expected to form reactive storm slabs overlying moist snow or a crust. The storm slabs should bond fairly quickly, but are expected to be most reactive during their formation, and in wind-affected terrain at upper elevations. Otherwise, the snowpack is strong and bonded, but melting quickly at lower elevations.

Monday Night

Cloudy with 15 to 20 cm of snow above 1200 m, potential moderate rain below. 30 to 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1500 m falling to 1100 m.

Tuesday

Cloudy with 15 to 40 cm of snow above 1100 m, potential moderate to heavy rain below. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level rising to 1200 m.

Wednesday

Mostly cloudy with 0 to 10 cm snow above 1200 m, light rain below . 10 to 25 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 1400 m.

Thursday

Cloudy with 30 to 60 mm of heavy rain up to 1600 m, potential snow above. 40 to 60 km/h south ridgetop wind. Treeline temperature +4 °C. Freezing level rising to 1700 m.

• Make conservative terrain choices and avoid overhead hazard.
• Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
• Watch for fresh storm slabs building throughout the day.
• Use small, low consequence slopes to test the bond of the new snow.
