Description:
There is a fair degree of uncertainty about the snowpack as we have not had the chance to make any direct observations for several days. Windslab instabilities could exist on higher elevation terrain of any aspect today, either from Wednesdays NW wind and snow event or those resulting from the last two days of light southerly snowfall. Anyone heading into the snow over the next few days should adopt a reasonably cautious investigative approach to steep terrain.
