For coastal areas covered by the Arctic outflow warnings, Environment Canada says a chilly airmass has begun pushing into B.C. from the Yukon, bringing wind chill values near -20 C, which are expected to persist through until mid-week.

Even the normally balmy south coast, which has seen cherry blossoms pop in some areas, will see temperatures five to 10 degrees below seasonal averages, according to Environment Canada.
