Avalanche problem #1 :
For Tuesday, the intense solar radiation will allow the surface to soften and it will be necessary to be attentive to the signs of instability of the snow which could lose its cohesion by becoming filled with water. With a VARIABLE rating, natural avalanches are unlikely but triggers of very small loose snow by skiers or snowboarders could be possible on steep slopes when the sun will heat the most. Although not widespread, these avalanches could lead you to obstacles such as rocks or trees lower down the slope.
With the slight cooling of temperatures, a melt freeze crust is present on the surface in the alpine and is being formed at treeline on a moist and well-consolidated snowpack. Below treeline, the snow is moist and cohesive.
The next few days will be mostly cloudy with no significant precipitation and the strong Westerly winds combined with a mercury remaining below freezing point will favor the formation of a freezing crust on the surface above 700m altitude. A thaw is however expected for Tuesday with sunny spring conditions.
This is the last avalanche bulletin of the season. As usual, your comments are always greatly appreciated by email at email@example.com. Thank you and have a good end of season!
