Points saillants

Today, the avalanche danger is MODERATE at upper elevations on any slope with fresh slabs of wind drifted snow. These wind slabs should be shallow, and on north-facing slopes they should be very easy to trigger. On low and mid elevation slopes or slopes either scoured or untouched by the wind, the avalanche danger is LOW.

This morning's very strong winds have drifted snow and formed fresh slabs that will be the only avalanche problem today. They should be very small because there is only a dusting of new snow for winds to move. North facing slopes have dry powder, and very strong winds this morning will find this dry snow and transport it as well.

Look for these fresh wind slabs at upper elevations on slopes loaded by these west and northwest winds.

Any fresh wind slab on a north facing slope should be very easy to trigger because it will be resting on weak, recrystallized powder.

Yesterday's warm temperatures heated the snow but caused few wet avalanches.

Snow and Weather

Yesterday, warm temps and strong sunshine warmed the snow on most slopes enough to make it wet. These slopes should be frozen solid with a hard ice crust this morning capped by a dusting of new snow. Only north facing slopes at mid and upper elevations still have dry powder.

This morning, a trace of snow has fallen, and temperatures are generally in the upper teens and low 20s F. Winds have been ripping across the high peaks this morning with gusts reaching 100 mph at 11,000 feet at 4 a.m. Otherwise, winds from the west and northwest have been averaging 10-30 mph gusting 30-50 mph.

Today will be cold and cloudy with snow falling but not accumulating. Very strong winds this morning should ease some today, but continue from the west and northwest. Temperatures will stuggle to climb into the mid 20s F.
