Heavy rainfall warning issued for this weekend in Metro Vancouver

Environment Canada has issued a rainfall warning for Metro Vancouver and Fraser Valley this weekend.

The forecast predicts that 100 mm of rain will hit the region from Saturday.

The total rainfall is expected to reach 60 mm over southern sections and up to 100 mm near the mountains. Howe Sound and the Sunshine Coast are also affected by this weather forecast.

A front will approach BC’s south coast on Saturday, and rain will begin for most areas Saturday morning. Environment Canada says the heaviest rain will occur Saturday night.

Between Saturday and Sunday morning, rainfall will vary from 50 mm from Richmond to Abbotsford to 100 mm closer to the mountains. Squamish and Sechelt could also see up to 80 mm of rain.

The warning was issued Thursday afternoon and will affect the following regions:

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

Meteorologists suggest that strong warming will accompany this system. Warming could cause “snow levels to rise well above mountain peaks on Saturday afternoon,” increasing the risk of flooding affecting already vulnerable areas.

ONE separate warning is currently also in effect for Metro Vancouver and it will last until Thursday night.
