Discussion: | The National Weather Service Forecasts- TODAY...CLOUDY WITH SCATTERED RAIN AND SNOW SHOWERS. AREAS OF FOG. HIGHS 36 TO 42. LIGHT WINDS. CHANCE OF PRECIPITATION 40 PERCENT. TONIGHT...CLOUDY. SCATTERED RAIN SHOWERS AND ISOLATED SNOW MONDAY...AREAS OF FOG IN THE MORNING. MOSTLY CLOUDY WITH A 20 PERCENT CHANCE OF RAIN AND SNOW. HIGHS AROUND 35. LIGHT WINDS. With very little new snow in the last week, the snow in place has had quite a bit of time to settle and bond. Conditions are fairly stable at this time. We have had a fair amount of wind in the last week which has placed a few small isolated slabs in wind loaded areas. Small slab avalanches have been sighted, both by natural release and man made. Watch wind loaded areas for increased danger as this next wave of moisture come through. Danger in the backcountry is moderate due to man made triggers. As we start to get the new snow it will be interesting to see how this bonds to the snow in place. Spatial variability will be quite high and layering should be interesting to see. The snow surface currently ranges from soft consolidated boot top powder to had icy slabs in areas with everything else inbetween. |
Tip: | There are 5 red flag indicators of avalanche conditions. Recent avalanches Wind is the only indicator at this time. And there is not much snow available for wind transport at this time. After the new snow begins we will start to see more indicators of instability |
