WESTERN WYOMING AVALANCHE ADIVSORY
Issued on Sat January 31, 2015 5:25 PM
Today was mostly clear with high thin clouds occasionally passing by, particularly during the morning. The expected warming did not occur and summit temperatures stayed in the teens due to cold air moving in east of the divide and due to winds. The winds were significant and had fifteen to twenty five mile per hour averages from the west during the morning. During the afternoon they became more northwesterly and increased to averages between thirty and forty miles per hour with gusts above fifty. These strong winds are blowing snow along the summits and ridgelines exposing the recent combined rime/rain/sun crusts in most wind affected terrain. Other snow surfaces include fine wind blown snow and in cold areas that are protected from these winds loose snow topped with surface hoar can be found.
FORECAST FOR Sunday, February 01, 2015
Sunday looks to be mostly dry as clouds increase in advance of a weather system that should bring snow to the area Sunday night. Temperatures should again be cool with mountain highs in the low twenties while northwest winds have averages between fifteen and twenty five miles per hour. The general avalanche hazard will remain Low in western Wyoming with a continued chance to trigger slabs in isolated areas where surface hoar that was buried in mid January still persists. These isolated areas of weakness are most likely to be found in shaded cold terrain above 8000 feet.
TREND FOR Monday, February 02, 2015 AND Tuesday, February 03, 2015
Snow is to fall Monday and Tuesday. There is uncertainty to the amount of snow to expect, however the avalanche hazard will elevate quickly as new snow will be falling on very slick sliding surfaces in higher elevation terrain.
