Discussion: | The National Weather Service Forecasts- TODAY...AREAS OF FOG IN THE MORNING. RAIN. SNOW LEVEL 300 FEET TONIGHT...SNOW SHOWERS MIXED WITH RAIN IN THE EARLY EVENING...THEN SCATTERED SNOW SHOWERS LATE. SNOW ACCUMULATION 1 TO 3 INCHES. LOWS AROUND 32. EAST WIND 5 TO 15 MPH. TUESDAY...MOSTLY CLOUDY. SCATTERED SNOW SHOWERS IN THE MORNING. SCATTERED RAIN SHOWERS. HIGHS AROUND 41. SOUTHEAST WIND 10 MPH SHIFTING TO THE SOUTHWEST IN THE AFTERNOON. Yesterdays above freezing temperatures throughout the day ahead of this rain helped the snowpack a little in rapid settlement and bonding. We did see a few small natural avalanches yesterday in N-NW facing slopes in places that had windloaded earlier in the week. We got just a little new snow up high overnight but most of the precip came in as rain. Currently temps have cooled off slightly around the region and are barely below freezing. Today we expect to see dirunal fluctuations with mid day warming to above the point of freezing once again in our mountain regions. The rain is to continue throughout the day. Avalanche danger is CONSIDERABLE at this time. Natural avalanches are possible. Human triggered avalanches are likely in places as well. Tonight temps should start to cool off a little again and the precip rates will slow. Avalanche danger will decrease at that time. Should we see slide activity today we do not expect to see any major size. Yet be aware danger exists in avalanche prone areas. Use caution and have a great day. Another day to avoid the Flume Trail perhaps. Hope you all had a good Easter. |
Tip: | spring avalanches - avalanches that typically occur after an extended period of warm weather saturates the snowpack with melt water. Usually this water will flow down through the snowpack until it either reaches the ground or an ice layer where it spreads out and lubricates the layer causing the snow above to slide. True spring avalanches are always wet snow avalanches. wet-snow avalanche - (or wet avalanche) - an avalanche consisting of snow which contains liquid water. In many instances, an avalanche will begin as a dry snow avalanche but turn into a wet snow avalanche as it descends to lower elevations. |
