advisory discussion

A weak low-pressure system will bring cloudy skies and strong winds to the area today which will likely limit the surface warming even on solar aspects. Field observations continue to highlight thin coverage and variable surface conditions. Some solar aspects that still hold contiguous panels of snow have seen many days of a melt-freeze cycle and are resembling a snowpack more typical to late spring. Conversely many shaded aspects are harboring a variety of surface crusts and loose dry faceted snow. While our recent weather patterns have led to relatively benign avalanche conditions isolated instabilities may exist throughout the range. Continue to practice safe travel techniques and keep in mind that the biggest hazards today may be the thin coverage and a variety of hard slick surface conditions. Plan your routes accordingly. Bring the proper equipment, pick your objectives carefully, and keep in mind that we may not see surface conditions soften up much today even on more solar aspects.

Weather and CURRENT CONDITIONS
weather summary

Today’s warm temperatures may be tempered by mostly cloudy skies and strong westerly winds. Expect temperatures to remain above freezing at all elevations today with highs in the mid 40°s at mid-elevations. Strong mid-slope winds should increase throughout the day with ridgetop gusts as high as 60 mph. 

Dry and warm conditions are likely to prevail for the remainder of this week with a slight chance of unsettled weather at the end of next week.
