"Significant" heat wave starts today in Metro Vancouver, Fraser Valley

A significant heat wave is expected to hit Metro Vancouver and the Fraser Valley starting today.

A heat warning, issued by Environment Canada, is in effect for the following areas:

Metro Vancouver – northeast including Coquitlam and Maple Ridge
Metro Vancouver – southeast including Surrey and Langley
Metro Vancouver – central including the City of Vancouver Burnaby and New Westminster
Metro Vancouver – North Shore including West Vancouver and North Vancouver
Metro Vancouver – southwest including Richmond and Delta

Fraser Valley – central including Chilliwack
Fraser Valley – east including Hope

The increase in temperature is due to a strong ridge of high pressure. It’s expected to last from Wednesday until Sunday morning, with the hottest days of the stretch being Thursday and Friday.

“The duration of this heat wave is expected to last at least three days and little relief is expected at night with elevated overnight temperatures,” Environment Canada warns. “These hotter than normal temperatures will increase the potential for heat-related illnesses.”
