The National Weather Service Forecasts-

TODAY...SLIGHT CHANCE OF RAIN IN THE MORNING...THEN RAIN LIKELY IN THE AFTERNOON. HIGHS AROUND 39. SOUTHEAST WIND 10 MPH BECOMING EAST 15 TO 25 MPH IN THE AFTERNOON.

TONIGHT...RAIN. SNOW LEVEL 500 FEET LATE. LOWS AROUND 35. EAST WIND 10 TO 20 MPH.

FRIDAY...RAIN LIKELY. SNOW LEVEL 1200 FEET IN THE MORNING. HIGHS AROUND 41. SOUTHEAST WIND 10 MPH.

Temperatures continue to remain just above freezing at the Mt Roberts Tram Summit elevation. This is allowing for continued settlement and consolidation of the snowpack.

The precipitation rate has been quite low and the snowpack is having enough time to process the water is it sinks slowly deeper into the snowpack.

Although there may be areas of weakness around rocks, on steep sections, near cornices at mid mountain elevations, the temperatures are remaining just a little cooler at the mountain top elevations in the primary starting zones.

So even through you might be able to make a little snow move in places at mid mountain elevations in general avalanche danger is low again today.

The increased precip rates for tonight into tomorrow will change that a little and the danger may rise slightly if the temperatures stay this warm....

Use a little extra caution in steep open areas at mid mountain especially on convex unsupported slopes above cliffs and rocks.

Let hope it cools off sometime soon and we go back into our typical western flow with moisture... right now everyting is coming out of the far south and will stay warm until conditions change.

Have a great day everyone....
