Colder temperatures overnight should help "lock" the snowpack in, where previously moist or wet from solar and or high freezing levels. The quality of the freeze is critical to monitor if traveling in avalanche terrain at the moment. Start early plan to finish early, check weather stations for temperatures and adjust once in the field if conditions aren't what you expected.

Avalanche Summary
A road patrol along the spray during the heat of the day was cut short by a call. +10 at 2300m and solar slopes continue to go through a natural cycle.
Snowpack Summary
Freezing levels climbed to 2800m on Saturday under clear skies. All S, E and N aspects have wind slabs at Alpine and Treeline elevations which rest on the Jan 30th interface made up of facets, sun crust or a dense slab layer. In lower elevations the snowpack has settled into a persistent slab overlying the weak January layers. All elevations show snowpack conditions that are sensitive to human triggering. Travelling at lower elevations involves ski penetration to ground if you leave any established trail. An isothermal snowpack can also be found in lower elevations in open sunny terrain.
You take all this and then add a high freezing level and sunny skies. You now have conditions that are even more prime for human triggering of avalanches.

Terrain and Travel Advice
- Triggering deep layers is more likely if the snow surface didn't freeze overnight.
- Avoid areas with overhead hazard.
- Keep in mind that human triggering may persist as natural avalanches taper off.
