The National Weather Service Forecasts-

TODAY...INCREASING CLOUDS. PATCHY FOG IN THE MORNING. SLIGHT
CHANCE OF SNOW IN THE AFTERNOON. HIGHS AROUND 32. NORTHEAST WIND 10 MPH SHIFTING TO THE EAST IN THE AFTERNOON.

TONIGHT...SNOW. SNOW ACCUMULATION 2 TO 4 INCHES. LOWS AROUND 26. EAST WIND 10 TO 15 MPH.

TUESDAY...SNOW IN THE MORNING...THEN RAIN IN THE AFTERNOON. SNOW ACCUMULATION 1 TO 3 INCHES. SNOW LEVEL 500 FEET IN THE AFTERNOON. HIGHS AROUND 37. SOUTHEAST WIND 10 TO 20 MPH.

Temperatures have fallen quite a bit in the last 2 days. Mt Roberts Tram summit temps fell from 26f to 19f. The Eaglecrest Summit Temps fell from 25f to 15f...

Winds have been under 20mph for the last 24 hours and under 10 mph for the last 12 ranging mostly from the SE to the SW.

We have received only 2mm of precip in the last 24 hours and only 7mm of precip in the last 48 hours. This added only 3cm of new snow after settlement is taken into consideration.

With not much new snow in the last 48 hours, not much wind in the last 24 hours, and cool temperatures in place avalanche danger is LOW at this time.

Natural avalanches are unlikely. Human triggered avalanches are unlikely as well. There may be a pockett of weakness or two near summit and ridgeline in wind loaded areas. But in general conditions are safe.

Danger levels will rise tonight into tomorrow as we start to see increased precipitation, moderate winds, and warming over the next 48 hours.

Happy Monday Everyone.

Tip:

Although spring avalanches and wet slides are slow... never underestimate their power.
