TODAY...SNOW LIKELY IN THE MORNING...THEN SLIGHT CHANCE OF RAIN
IN THE AFTERNOON. LITTLE OR NO SNOW ACCUMULATION. HIGHS AROUND 36. SOUTHEAST WIND 10 MPH SHIFTING TO THE NORTHEAST IN THE AFTERNOON.

TONIGHT...MOSTLY CLOUDY. SLIGHT CHANCE OF SNOW LATE. LOWS AROUND 31. NORTHEAST WIND 10 TO 15 MPH.

WASHINGTONS BIRTHDAY...SLIGHT CHANCE OF RAIN AND SNOW IN THE

1 INCH. SNOW LEVEL 1000 FEET IN THE AFTERNOON. HIGHS AROUND 36. SOUTHEAST WIND 10 TO 15 MPH.

Temps are still staying below zero in the starting zones, and new snow has come in with only light winds.

Eaglecrest is showing about 15cm of new snow, while Mt Roberts seems to have gotten only about 7cm. Winds peaked at about 22kts but have since layed down. They have been consistent out of the SouthEast.

Expect wind loading on N slopes, and cross loading on E and particulary W slopes. This means that the White, Behrends, and Thane Road slide paths have all been cross loading with this storm.

Since both winds and amounts of snowfall have been moderate sizes of any slides are expected to be small and confined to the new snow.

Avalanche Danger is MODERATE today: Natural avalanches unlikely, potentially destructive avalanches unlikely to come near or reach developed areas. Human triggered avalanches possible.

Wind loaded slabs possible on steep terrain. Use caution in or under steeper terrain and in avalanche zones.

In the backcountry use caution on steeper North and West aspects. Expect cross loading mid-slope.
