TODAY...MOSTLY SUNNY. PATCHY FOG IN THE MORNING. HIGHS AROUND
31. NORTHEAST WIND 5 TO 15 MPH.

TONIGHT...PARTLY CLOUDY. PATCHY FOG. LOWS 14 TO 22. NORTHEAST
WIND 5 TO 15 MPH.

THURSDAY...MOSTLY CLOUDY. CHANCE OF SNOW. HIGHS AROUND 29. EAST WIND 10 MPH.

Eaglecrest and Sheep Mountain Temperatures fell by 3 and 6c degrees respectively over the last 12 hours... While interestingly the Mt Roberts tram weather station gauges showed a 2degree drop with a 2 degree rise to stay the same...

Winds have been under 10mph for the last 12 hours but were 20-30 for the 24 hours previous to that which created some windloading in starting zones. Where winds had been out of the south during the higher winds they are now out of the North.

There has been no measurable precip in the last 15+ hours and we saw 14mm in the previous 48 hours. After settlement this left us with only about 10cm of new snow. If you look about 60 hours its about 7cm additional for a total of nearly 17cm.

This new snow came in with some light to moderate windloading.

Expect to see some small pockets of windslab near summit and ridgeline that are holding a little more snow. These pockets may be sensative and have the ability to be skier triggered in places.

Avalanche danger is MODERATE today. With no snow in the forecast and light winds the danger level is decreasing throughout the day and we expect it may be LOW by tomorrow.

Natural avalanches unlikely, potentially destructive avalanches unlikely to come near or reach developed areas.

Human triggered avalanches remain possible in those isolated pockets.

Today with cool temps and light winds with no precip will give this new snow time to settle and bond and stability will continue to increase.

Enjoy a beautiful day!

Tip:

There will be a one day FREE avalanche awareness class with companion rescue training held at Eaglecrest on Sunday January 20th from 9-4pm.

This class will teach you to identify avalanche terrain, how to do weather assesments and read what that may do to avalanche stability. We will discuss snowpack layering and its relation to stability. You will learn about safe travel practices in avalanche terrain. How to dig snowpits and make stability assesments for yourself. How to use your avalanche rescue gear, and perform companion rescue.

We look forward to having you involved
