TUNE IN: Tune into The Weather Network on TV as we continue to track this powerful fall storm all weekend long. Ian Jacobs will be LIVE on location!


A powerful fall storm pushing into BC on Friday could result in over 100 mm of rain for some places through the weekend. 

"The first full weekend of fall will be a stormy one in BC, as a powerful Pacific low approaches from Alaska." says Gina Ressler, a meteorologist at The Weather Network. "A weak front will spread light rain down the coast on Friday, but the significant rain and wind will move in on Saturday."

Forecasters say the heavy rain could be enhanced by the moisture left over from Typhoon Pabuk, which was centred near Japan on Wednesday.

"Rainfall amounts will vary across the lower mainland, but some areas (especially those at higher elevation) could see upwards of 100-150 mm," adds Ressler. "Significant snowfall is also expected in the higher mountain terrain." 

The most significant rainfall is expected on western Vancouver Island and the western shores of coastal mountains including Howe Sound, where up to 200 mm could fall by the time all is said and done.

Metro Vancouver can see a range of 80 to 120 mm, with locally higher amounts possible. 

Forecasters say strong winds will accompany the storm, with gusts of up to 110 km/h expected to hit Haida Gwaii and the North Coast Friday night. 

"Fall marks the return of the rainy season to the BC coast. In Vancouver, October typically sees twice as much rainfall as September. And in Prince Rupert, October is the wettest month of the year, averaging nearly 400 mm of rain," says Ressler. 

Residents are being urged to stay updated on the weather warnings and adjust any travel plans accordingly.
