Lo esencial

New snow and warm temperatures are increasing the load in areas where weak layers persist near the base of the snowpack. Some potential may exist for snowmobilers to trigger persistent deep slabs with depths to six feet in isolated areas. Pockets of dense surface slab could also be triggered by riders or skiers in very steep avalanche prone terrain at the mid and upper elevations.

    In isolated areas weak, faceted snow persists near the base of the snowpack. Some potential may remain for snowmobilers, or multiple snowmobiles on the same slope, to trigger dangerous hard slab avalanches up to six feet deep. In these areas, previous tracks on a slope are not an indication of stability. If a member of your party gets stuck on a suspect slope, refrain from adding additional weight to the snowpack by helping them get unstuck.

    Pockets of dense wind slab formed by southwest winds exist in steep avalanche starting zones and cliff areas above an elevation of 8,000 feet. These wind slabs are up to two feet in depth.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )A moist spring storm system will pass over the area. Moisture in the form of convective snow showers in the mountains and rain showers in the valleys will continue to impact the region. At the upper elevations six to nine inches of new snow accumulation is likely during the next 24 hours. Winds are forecast to be southwest to west at speeds of five to ten miles per hour overnight and veer to the northwest on Sunday and increase to speeds of 15 to 20 miles per hour. Temperatures at 10,500 feet will drop into the lower 20s overnight and rise into the upper 20s on Sunday. Temperatures in the valleys will drop into the upper 20s overnight and rise to near 40 on Sunday.The general avalanche hazard is expected to be MODERATE at the higher elevations where pockets of soft slab up to two feet in depth lie upon hard old snow surfaces. These slabs could be triggered by skiers or riders in very steep avalanche starting zones and cliff areas. The general avalanche hazard at the lower elevations is anticipated to be LOW.
