</style><p class="p_CC664AAA"><span class="s_3FE45715">20-30 cm of storm snow fell Sunday into Monday and temperatures warmed up to -2 at tree line in the south of the region (and +2 near Barkerville). The new snow sits on a complex snowpack and there are three active weak layers that professionals are monitoring:</span></p><p class="p_CC664AAA"><span class="s_3FE45715">1) Down about 40-80 cm is a crust and/or surface hoar layer buried mid-January. The surface hoar is up to 10 mm in size, found at all elevation bands and very reactive on north east aspects between 1900-2600m.</span></p><p class="p_CC664AAA"><span class="s_3FE45715">2) Deeper in the snowpack, the early-January persistent weak layer is found 50 to 130 cm below the surface. It is composed of surface hoar on sheltered slopes and sun crust on steep solar aspects and found at all elevation bands. Snowpack tests show sudden fracture characters with easy to moderate loads and high propagation potential. </span></p><p class="p_CC664AAA"><span class="s_3FE45715">3) Another weak layer buried mid-December consisting of a facet/surface hoar/crust combination is buried 110 to 170 cm deep. It is most problematic at and below tree line.</span></p><p class="p_CC664AAA"><span class="s_3FE45715">A rain crust buried in November is 100 to 200 cm deep and is likely dormant for the time being.</span></p><p class="p_CC664AAA"><a id='GoToAdded' href="http://www.avalanche.ca/mountain-information-network/submissions/ee9d5ef2-3539-4eb4-8d5a-8c9c15691c24" target="_blank"><span class="s_B5813F7D">See here for a good summary of snowpack test results</span></a><span class="s_3FE45715">.</span></p>
