Discussion: | The National Weather Service Forecasts- TODAY...RAIN. TEMPERATURES REMAINING AROUND 39. SOUTHEAST WIND 5 TO 15 MPH. TONIGHT...RAIN. LOWS AROUND 36. SOUTHEAST WIND 5 TO 15 MPH. SUNDAY...RAIN. SNOW LEVEL 1200 FEET. HIGHS AROUND 37. SOUTHEAST WIND 10 MPH SHIFTING TO THE SOUTHWEST IN THE AFTERNOON. SUNDAY NIGHT...RAIN AND SNOW LIKELY. LOWS AROUND 32. SOUTHEAST WIND 5 TO 15 MPH. Temperatures have been quite warm for the last few days. We received 1.2\" of rain that has been saturating the snowpack all the way to summit elevations in the last 24 hours. With another 1/2 inch of rain in the forecast today natural wet avalanches remain possible. Human triggered avalanches also remain possible but are harder to trigger in these wet snow conditions. Be cutious of steep convex slopes. Overnight into tomorrow the temperatures should fall slightly helping with stability but at the same time we also have another 1\" of precip in the forecast. |
Tip: | Wet Snow Avalanche: Most avalanche professionals make a hard distinction between dry snow and wet snow avalanches because they are such different beasts. They are caused by different processes, they fail and fracture differently, they are triggered differently and they move differently down the slope. Really, there is a continuum between wet and dry avalanches and professional workers use the words: dry, damp, moist, wet and saturated to describe the continuum. Wet avalanches cause relatively few avalanche fatalities, consequently, they are studied less and are not as well understood. |
