VANCOUVER — An atmospheric river weather system has hit much of coastal British Columbia, bringing heavy rain, strong winds and the risk of flooding.

Environment Canada has issued about two dozen wind and rain warnings, covering much of Vancouver Island, Metro Vancouver and the south and central coasts.

It says the inland central coast should expect its heaviest rain this afternoon, with up to 70 millimeters on the way.

However, the deluge is not expected to peak on Vancouver Island until this evening, while in Metro Vancouver it could be by early afternoon Saturday, provincial election day.

The weather bureau says western and interior Vancouver Island will receive up to 100 millimeters of rain, and possibly more than 200 millimeters in the mountains, while Metro Vancouver will receive up to 70 millimeters.

The atmospheric river will also spill over the southern interior of British Columbia and prolonged periods of heavy rain are expected to persist through the weekend.

The system triggered flood monitoring by the River Forecast Center for several rivers along the central and south coasts, Lower Fraser tributaries, Metro Vancouver waterways and Vancouver Island.

Wind warnings have also been issued for exposed sections of Haida Gwaii, the north and central coasts and northern Vancouver Island.

Environment Canada also maintains snowfall warnings along the British Columbia-Yukon border, which could bring up to 25 centimeters to some areas.

It says the rapid accumulation of snow can make driving difficult, so travelers are asked to be careful on the roads.
