Chances of Avalanches?
Expected Size?
Travel and Terrain Advice
- Avoid exposure to overhead solar avalanche terrain, avalanches may reach the end of run out zones.
Avalanche Problem 2: Cornices
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Large cornices are hanging off ridge lines and will weaken with daytime warming and intense solar radiation. Minimize your exposure to these looming hazards.
Travel and Terrain Advice
- Avoid slopes when the solar radiation is strong, especially if they have large cornices overhead.
- Minimize exposure to overhead hazard from cornices.
Avalanche Summary
Solar aspects producing loose moist avalanches up to size 3, a few of which have gouged to ground.
The Connaught creek skin track has been buried several times this week from avalanches originating from steep solar aspects in the alpine running to valley bottom.
Snowpack Summary
Surface hoar growth in shaded locations. Snowpack is well settled with no notable layers in the upper snowpack. Expect surface crust on all aspects and elevations except North and East in the Alpine and upper treeline. Solar aspects will become moist and unstable as temps rise over the day. Cool dry snow found on high polar aspects.
Weather Forecast
Weather models are competing for this years spring show and can't agree if the sun will shine or rain will fall. The conservative option is to expect sun in the AM and cloud in the PM, freezing levels to 2700m with a chance of rain (1-3mm). Winds will be light, valley bottom temps up to +7 and an alpine high of +3. Temperatures dropping tomorrow.
