Metro Vancouver weather: Rainfall warnings possible as jet stream moves onshore
Residents of Metro Vancouver should make the most of clear skies before another strong wave of storms arrives. The region will see a brief stretch of sunshine before a wetter and windier pattern dominates again.
Weekend weather outlook
Environment Canada meteorologist Brian Proctor told V.I.A. 7 that the Lower Mainland will enjoy a bright start to the weekend after two frontal systems brought heavy rain and wind earlier in the week.
"The rain during rush hour was more intense than we expected, although rainfall totals were aligned with the forecast,"

Rainfall warnings were issued for higher-precipitation areas such as the North Shore and Port Coquitlam. Friday will see clear skies and temperatures dipping to around 6°C overnight. Saturday is expected to be the best day of the week, with blue skies and a cool 5°C overnight low.
Next storm system on the way
The upcoming week will bring the return of stormy weather as the Pacific jet stream moves onshore, driving a series of successive systems toward the British Columbia coast. Sunday’s forecast resembles Wednesday’s storm, bringing rainfall amounts of 20 to 40 millimetres across most of the Lower Mainland.
- North Shore, Port Moody, and Port Coquitlam may see between 40 and 70 mm of rain.
- These areas could receive new rainfall warnings, according to Proctor.
Summary
After a brief reprieve of sunny skies, Metro Vancouver faces another cycle of Pacific storms as the jet stream delivers heavy rain to the region once more.
