More than 50 mm falls before the weekend.
A rain forecast issued earlier this week has been updated to include even more rain for Metro Vancouver tomorrow.
For residents around the lower mainland on Friday 17 September could see up to 70 mm of precipitation, says Environment Canada in the updated warning, which is now classified as a warning due to safety concerns.
Also added to the warning is the expectation of winds up to 60 km / h coming from the southeast.
“A robust frontal system will bring heavy rain to the BC South Coast on Friday. Rain begins late overnight and intensifies during the day on Friday. As the system moves through, heavy rain and gusts will ease Friday night,” says Environment Canada . “Heavy rainfall can cause flooding and water accumulating on roads. If visibility is reduced while driving, turn on the lights and maintain a safe distance.”
More than 70 mm can fall in the Howe Sound and North Shore mountains.
So much rain can cause problems for anyone who has not prepared for the city’s rainy season, Environment Canada adds.
“Consider clearing leaves and debris from drainage areas, as the heavy rains could pose problems with potential local floods,” the agency states.
The province also warns residents in the area ahead of the storm and reminds people to be wary of falling trees, fallen power lines and floods (especially near riverbanks that can erode quickly).
“The River Forecast Center also warns of high currents and potential flooding for parts of Vancouver Island and the south coast,” they said in a news release.
The warning covers the entire Metro region, including:
- Central including the city of Vancouver Burnaby and New Westminster
- North Shore including West Vancouver and North Vancouver
- Northeast including Coquitlam and Maple Ridge
- Southeast including Surrey and Langley
- Southwest including Richmond and Delta
The warning has also been issued for the surrounding regions:
- The island of Vancouver
- Fraser Valley
- Howe sound
- Sunshine Coast
