Lo esencial

The avalanche danger is Moderate above 8,000 feet this morning and will rise to Considerable later in the day. New snow and wind has formed slabs that will become increasingly sensitive to human triggers today. With more snow expected along with increasing temperatures, expect slabs to become easily triggered in steep terrain. While natural avalanches are less likely, it will be important to pay attention to changing conditions and assess the new snow for signs of instability. Recent avalanches, shooting cracks and whoompfing are clear indicators that it is time to choose more conservative terrain. Below 8,000 feet avalanches are unlikely and the danger will be Low.

    New snow amounts over the last 24 hours range from 6-8”. Snow densities are light, in the 6-8% range. New snow amounts during the day today will be in the 3-5” range and be higher in density. This will help to create “upside down” conditions and make triggering more likely as the new snow accumulates. Moderate south and southwest winds will help to build slabs up to 2 feet in depth in the upper elevations. Be on the lookout for signs of recent loading and expect avalanche activity to be on the increase as the day progresses.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )The National Weather Service in Riverton has issued a Winter Storm Watch beginning tomorrow afternoon, Monday and continuing until Tuesday night. Scattered snow showers will taper off tonight as the current system exits the area. Total overnight accumulations will be light, in the 1-3” range. As the next system approaches tomorrow, snowfall will increase as will temperatures. Daytime accumulations tomorrow will be in the 4-6” range in all forecast areas. Overnight lows at ridgetops will be in the single digits before rising into the upper twenties tomorrow. Winds will be out of the west and southwest at 15-25 mph.The avalanche danger will start out Low in the morning and increase to Moderate in the afternoon. Avalanche activity will be confined to the new snow and be more pronounced in the upper elevations. The actual timing of the increase in danger will be dependent on the accumulation of new snow. Paying attention to changing conditions will be important in making informed decisions tomorrow. Be on the lookout for signs of active loading of slopes as well as obvious signs of instability such as avalanches, shooting cracks and whoompfing.
