Note from the SLRD: The Special Weather Statement below was issued by Environment Canada and impacts Areas C and D of the SLRD, as well as the District of Squamish, Village of Pemberton and Resort Municipality of Whistler.
Issued at 2017-12-18 13:10 UTC by Environment Canada:
...Snow likely over higher terrain on Tuesday...
...Flurries possible on Thursday...
...Colder after Thursday for the rest of the week...
The weather will become more wintery over the south coast this week.
On Tuesday a deepening low pressure system will track across northern Washington State close to the B.C. border. This system will combine plentiful Pacific moisture with cool easterly winds near the surface. The resulting weather will be a mixture of rain and snow beginning tonight over most South Coast communities. Snowfall amounts will vary significantly from region to region and especially with elevation.
With the strong easterly low level winds, East Vancouver Island and Victoria will likely be the snowiest regions across the South Coast on Tuesday. Higher elevation passes like the Malahat and the Hump should see significant accumulations with at least 5 to 10 cm of snow expected. Communities away from Georgia Strait will also be the most likely to see some snowfall accumulations. Over the mainland South Coast there will be lesser snow amounts with about 5 cm of accumulation over higher urbanized communities. Howe Sound and Whistler will get closer to 10 cm Tuesday
Precipitation will ease Tuesday night and a break in the weather is expected Wednesday. Much of the snow that falls Tuesday will probably melt on Wednesday.
A little snow is likely Thursday over the mainland coast as an Arctic front drops down from the BC Interior. The Arctic front will usher in much colder air for the rest of the week. By Friday night the lows will plummet to between minus 5 and minus 10 across the South Coast Daytime highs on Saturday will struggle to reach the freezing mark.
