With the incoming storm, south winds are forecasted in the 20 and 30 mph range. These winds combined with new snow will do good job of building new wind slabs on north facing and cross loaded terrain. Today and over the weekend, watch what the wind is doing. What direction is it coming from? Is it loading up high on the slopes, or is it blowing so hard that the snow is loading further down the slope or not loading at all?
Forecasts are calling for 2-10 inches today and an additional 3-8 tonight depending on where you are in the PAC advisory area. This new snow will be falling on a multitude of different existing snow surfaces. The number one suspect surface to watch for over the weekend will be melt freeze crust. The new snow on crust will have a heck of a time bonding and will be ripe and ready to get pushed around. If only a few inches of snow falls, the problem will be merely dry loose sluffs, however, tonight and into tomorrow as the snow piles up storm slabs will take the place of what was small manageable sluffs.
***This is the last daily avalanche advisory for the season.
