Rugged travel below 1900m may be the biggest hazard, where a breakable crust caps the snowpack.

Allow extra time for your egress!

• Confidence is due to a stable weather pattern; little change is expected for several days.

Small solar triggered sloughing was observed today from steep, rocky features in the alpine.

There were reports of a few fresh avalanches up to size 2.5 locally and from neighboring operations on Wednesday - some triggered by cornice fall.

Artillery control in Rogers Pass on Monday produced numerous avalanches from size 2.5 to 3.5. There was also a natural avalanche cycle during this stormy period, with avalanches running to valley bottom.

A breakable surface crust exists on all but high alpine slopes, which is problematic for skiing.

The mid and lower snowpacks are well settled and strong.

High pressure remains dominant over the next several days. An alpine temperature inversion will remain, however not as strong as Saturday.

Tonight Cloudy. Alpine low -5°C. Light North ridgetop winds. Freezing level (FZL) at valley bottom.

Sun Mainly sunny. High -4 °C. FZL 800m. Light N wind.

Mon Mix sun/cloud. Low -7 °C, High -3 °C. FZL 1100m. Light W wind.

Tues Mainly cloudy. High -6°C. FZL 1000m. Light NW wind.

• A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Watch for areas of hard wind slab on alpine features.
