Discussion: | The National Weather Service Forecasts- TODAY...CLOUDY...LOCALLY WINDY. SCATTERED SNOW SHOWERS. HIGHS TONIGHT...MOSTLY CLOUDY. LOWS 16 TO 24. NORTHEAST WIND 15 MPH. HIGHER GUSTS NEAR INTERIOR PASSES LATE. SUNDAY...DECREASING CLOUDS. HIGHS AROUND 32. NORTHEAST WIND SUNDAY NIGHT...PARTLY CLOUDY. LOWS 16 TO 24. NORTHEAST WIND We have not received any snow in the last 7 days. We have had constant winds from 20-80 mph during that times. There has been a great deal of scouring and also wind loading. Spatial variability remains very high. Snow conditions will vary greatly from place to place. Natural Avalanches are becoming less and less of a concern the longer this wind condition exists. The slabs in place are bonding and becoming harder and there is less loose snow available for transport to trigger the slide naturally. The ability for human triggered avalanches may still exists in places. There are still pockets of windloaded slab that could be skier or snowmobile triggered. Avalanche sizes are not expected to be large should they occur. Danger levels are LOW at this time. |
Tip: | While shoveling might seem elementary, it consumes most of time during an avalanche rescue. For maximum effi ciency, make your hole about one ?wingspan? wide and excavate Avalanche debris is usually hard, so chop the snow into blocks, then scoop. Try ?paddling? rather than lifting each scoop. Avalanche professionals recommend aluminum shovels over Single Rescuer Once the victim is located, leave probe in place as a marker. Probe depth markings will also aid in determining optimum hole size. Start moving the snow out the sides of your hole. When the snow surface rises above your waist, start moving snow downhill, out the end of your hole. Attempt to get to the victim?s face as soon as possible. Uncover their head and It is not necessary to dig the entire hole to the depth of the victim. Excavate at an angle or in steps, as shown. Multiple Rescuers If two shovelers are available, work sideby- side, following the guidelines above. If more than two shovelers are available, then two should begin shoveling just downhill The uphill shovelers then move their snow to this position and the remaining downhill shoveler should move it to the surface. |
