It looks like we did not receive any real precip in the form of rain or snow yesterday or last night. Temperatures yesterday at the Tram weather station got to 2 degrees C during the day while only falling a degree and a half at night. Winds were out of the North for the most part, and stayed under the 10 mph mark. The Urban hazard is low again today. With the snowpack that exists right now these stable temperatures will help to heal the snowpack. In the spring time the snow all wants to be the same temperature. This eventually eats up the weaker layers that could cause the snowpack to fail.. At the moment it is looking like we will see for moisture for the weekend. The NWS is forecasting the temperatures to be warm enough for rain during the day with a chance of snow in the evening. Remember, this forecast is for the urban zones only. Hazardous backcountry conditions exist. Be cautious of the snowpack where it may be shallow as these places are great trigger spots for avalanches. |
| Tip: | In the spring time we start to worry a little more about a different type of avalanche. Wet slides occur generally in the spring, however here in Juneau happen whenever it rains or is warm. The dangerous thing about these is not necessarily the larger size but the pushing power of the snow. The top layer of snow entrains other snow as it glides down the mountain. When it stops the snow feels like concrete and can often have earth mixed in with it. Grouse hunters especially be aware as the avalanche paths that guard tree fingers are perfect places for these slides to happen, and often the sun is shining when the hooters are most active. This link from the US Forest Service breaks down wet avalanches nicely. http://www.fsavalanche.org/encyclopedia/wet_snow_avalanche.htm |
