    North and West winds have created stiff thin wind slabs. These slabs have been fairly stubborn, but you may be able to trigger one in steep and or convex terrain. Keep an eye out for large cornices which may fail without obvious rhyme or reason.

Snowpack Summary

North and west winds (mainly from the north) have created isolated stiff wind slabs 5 to 10cm thick on lee slopes. On other slopes you may find tired old wind slabs, a sun crust on all solar aspects, surface hoar, surface facets, and/or up to 5 cm of soft snow over a widespread supportive rain crust in wind sheltered areas. The snowpack is generally strong and well settled. However, large cornices may become weak with daytime warming.
