Flood Risk for BC Lower Mainlands

Laurissa Anyas-Weiss, content producer

January 6, 2010 — 300 mm of rain has fallen in Tofino with all the roads closed. Vancouver is about to slide into the Pacific.

Rain continues to fall on BC's lower mainland and Vancouver Island (see below for recent amounts). The western edge of Metro Vancouver could see a letting up of rain this afternoon. By the time this system moves out on Friday more than 100 mm of rain is possible locally.

The Metro Vancouver and Fraser Valley areas are at risk for flooding as many storm drains are still covered with snow. To avoid flooding in your area check to see if storm drains are clear and shovel away snow if necessary.

In addition to the rain, Vancouver Island and the Strait of Georgia will also get strong winds gusting up to 70km/h.

The BC interior will see significant snow accumulations for higher elevations turning to rain in the valleys.

The heavy rain has caused road closures with the Trans Canada highway closed between Chilliwack and Hope due to a mud slide. Highways 3 and 5 are closed from Hope because of the avalanche risk. As well, huge pot holes, flooded roads and parking lots are being reported across lower mainland. South of the border, the state of Washington is on the verge of declaring a state of emergency due to the rain.

Rainfall and Snowfall Warnings are in effect for most of BC.
