Snowpack Summary
30-50 cm of new snow mixed with rain has fallen over the South Coast region between Tuesday morning and Wednesday morning. This new snow likely sits on a melt freeze crust at treeline. Below treeline the new snow is likely moist to wet depending on how much rain fell during Tuesday night's storm. At upper elevations, where the recent precipitation fell as snow, over 130 cm has accumulated since the stormy weather began last week. At upper elevations in the north of the region near Squamish, there may be a weak layer of surface hoar (feathery crystals) buried approximately 80-100 cm. Information on the strength and distribution of this layer is very limited.
