TODAY...MOSTLY CLOUDY. CHANCE OF RAIN IN THE AFTERNOON. HIGHS AROUND 49. LIGHT WINDS BECOMING WEST WIND 10 MPH.

TONIGHT...CLOUDY. CHANCE OF RAIN. LOWS AROUND 34. SOUTHEAST WIND 5 MPH.

TUESDAY...MOSTLY CLOUDY. CHANCE OF RAIN. HIGHS AROUND 49. SOUTHEAST WIND 10 MPH.

Yesterday temperatures reached 6.7C(44F) at the Tram and 5.6C(42F) at Eaglecrest. Both the Tram and the Eaglecrest weather station did not drop below freezing last night. Winds were calm and there was no precipitation at any of the stations over the past 24 hours.

It appears that our sunny days have come to and end for now. There is some light rain the forecast for later today. In the next 24 hours winds are forecasted to remain calm and precipitation to be light (0.04?).

I don?t anticipate the light rain to have much of an effect on the snowpack at this time. Without a solid refreeze last night we did not gain any additional strength in our upper start zones. We are moving towards more of a spring isothermal snowpack as temperatures remain above freezing in our start zones. We may start to see some glide avalanches in the days to come as our spring cycle starts shape up.

The avalanche danger is LOW today. Remember to minimize exposure in avalanche runouts in the heat of the day when wet slides normally occur.

This is not a backcountry forecast. Backcountry travelers be sure to do your own terrain and snowpack evaluation as spatial variability exits.

Tip:

Here is a description of a glide avalanche from the Forest Service National Avalanche Center?s website.

?Glide occurs when the entire snowpack slowly slides as a unit on the ground, similar to a glacier. Don't mistake glide for the catastrophic release of a slab avalanche that breaks to the ground. Glide is a slow process, that usually occurs over several days. Glide occurs because melt water lubricates the ground and allows the overlying snowpack to slowly \"glide\" downhill. Usually, they don't ever produce an avalanche but occasionally they release catastrophically as a glide avalanche. So the presence of glide cracks in the snow do not necessarily mean danger. It's often difficult for a person to trigger a glide avalanche but at the same time it's not smart to be mucking around on top of them and especially not smart to camp under them.?
