Prepare for the deluge of rain anticipated this weekend: Environment Canada has issued a rainfall warning for the Metro Vancouver region.
The approaching storm system will bring between 50 to 80 mm of rainfall for Howe Sound and the North Shore mountains beginning overnight and into Saturday, with lesser amounts in municipalities south of Burrard Inlet. Another storm system is expected to arrive on Sunday.
The high pressure system that brought sunshine and warm weather to much of the province shifted east due to the approaching series of storms. It is anticipated the storm systems will merge the two jet streams into a single river of subtropical moisture.
With the expected volumes, localized flash flooding in low-lying areas is a possibility and washouts could occur near rivers, creeks and culverts. Furthermore, due to the drought conditions experienced over the summer, the region’s soil has less capacity to absorb water quickly.
Drivers are advised to exercise extra caution as road surfaces may become slippery.
With the forecast of the return of rain in the South Coast, the provincial government lifted the campfire ban earlier today. However, Metro Vancouver Regional District’s Stage 3 water restrictions remain in effect until further notice.
On July 29, officials said it would require 150 mm of continuous rain to return reservoirs to 100 per cent full levels.
