| Discussion: | The National Weather Service Forecasts- TODAY...MOSTLY CLOUDY. SCATTERED RAIN AND SNOW SHOWERS. HIGHS TONIGHT...CLOUDY. SCATTERED RAIN SHOWERS AND SNOW SHOWERS. LOWS AROUND 30. LIGHT WINDS. MONDAY...DECREASING CLOUDS. HIGHS AROUND 35. NORTHEAST WIND 10 MPH SHIFTING TO THE NORTHWEST IN THE AFTERNOON. We had a good storm this last week leaving 2-5feet of snow in our local mountain region. We had high winds and lots of windloading during that time. Winds from 30-60 out of the SSE heavily loaded our NNW starting zones. Other starting zones are questionable as well. Things have mellowed out over the last several days. We have received 17mm of precip in the last 48 hours and only 10mm in the last 24 hours. This left a few inches of new snow in the mountain regions and continued to load faces in places. Winds were ranging to over 30 mph yesterday but have fallen today into the 10-20 range today and are expected to remain calm. Temperatures in the mountains now are very near freezing with Eaglecrest being at -1.5c and the tram at .1c. These near freezing temps help the snowpack to settle and bond more rapidly, but with lots of deep instability it may take some additional time stabilize. Temperatures today are to remain near the same. The winds are to be calm for the most part. There isnt much notable precip in the forecast. Avalanche danger is MODERATE at this time. Natural avalanches unlikely, potentially destructive avalanches unlikely to come near or reach developed areas. Human triggered avalanches possible. Be cautious in the mountain starting zones. Use extreme caution on steep slopes. Especially convex slopes, unsupported rolls, near terrain traps and cliffs. Things are getting better. But I would think if your the unlucky person who steps in the wrong place it could still be a bad day. Use good terrain selection habits and have a great day. |
