Storm slabs may need another day to bond at upper elevations.
Pay attention to changing conditions with elevation and aspect.
Storm slabs are expected to be most reactive in wind affected terrain at upper elevations. Cornices may be large and fragile, give them a wide berth when traveling on or below ridges.
Wet loose avalanches will be possible when the snow surface is wet or moist. Use good sluff management techniques.
No new avalanches were reported aside from some minor sluffing during periods of heavy rain. Observations have been very limited in the region.
Looking forward, storm slabs are expected to be reactive to human-triggering at upper elevations.
If you head into the backcountry, please consider submitting a MIN report.
Stormy conditions and fluctuating freezing levels over the past few days have deposited over 100 mm of rain in parts of the region at lower elevations, with snow up high. An additional 15 to 30 cm of snow is expected to fall overnight above 1200 m before we get a break from the storm on Wednesday. The new snow has likely formed reactive storm slabs that should bond fairly quickly, but may need another day or two to bond. Slabs are expected to be most reactive in wind-loaded terrain at upper elevations. Otherwise, the snowpack is strong and bonded. At lower elevations, the snowpack is rain-saturated and thins out quickly.
