Environment Canada issued special weather statements for several parts of the province on Wednesday, warning residents of colder-than-average temperatures starting Friday night.

Environment Canada predicts that temperatures could be up to 20 C colder than normal for this time of year in the central and southern Interior of B.C., and up to 10 C colder for the South Coast.

Gusting winds will make the air feel even colder, the weather agency says.
