Not only is the Metro Vancouver weather forecast calling for heavy rainfall, but it is also calling for strong winds gusting to 80 km/h, too. 

Environment Canada has issued a rainfall warning for the Metro Vancouver region due to a storm bringing heavy rain into the area on Friday (Sept. 17). Rainfall amounts of 50 to 80 mm are expected, with the higher amounts over Howe Sound and the North Shore mountains.

The rainfall will intensify as the day progresses, with southeasterly winds gusting to 80 km/h this afternoon and early evening.

The heavy rain and strong winds are expected to ease later tonight as the system moves through the region. 

Heavy downpours can cause flash floods and water pooling on roads. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.

The warning is in effect for Metro Vancouver, Fraser Valley, Howe Sound, Whistler, the Sunshine Coast, and East Vancouver Island between Qualicum Beach and Fanny Bay.

While the rainfall warning isn't in effect for Saturday, the forecast includes the risk of thunderstorms in the afternoon with a 60 per cent chance of showers.

Environment Canada is calling for a warmer than average autumn on the south coast of B.C. in its complete forecast released Sept.1 — the first day of meteorological fall. 

This winter La Niña could also impact temperatures in the Lower Mainland region, as well as the amount of snow. Currently, the federal weather forecaster's models are indicating that there is a "medium" chance of a weak La Niña this winter but that its effects won't show until December.
