Extreme Wind And Rain To Hit B.C. Coast

A new storm system moving though B.C.'s North and Central coast threatens to bring rain and extremely high winds to an area already beaten down by wild weather.

Environment Canada says an intense Pacific frontal system is moving through the area, with winds of up to 100 km/h moving from the North Coast and Haida Gwaii down into the Central Coast on Tuesday.

The same system has prompted a rainfall warning for inland sections of the North Coast, with up to 75 mm of rain forecast over the next 48 hours for Kitimat and Stewart. Heavy rains earlier this month caused flooding that wiped out the only highway between Stewart and the rest of the province.

A high streamflow advisory has also been issued for B.C.'s North and Central Coast. River levels are expected to rise rapidly Tuesday through to Thursday, but no major flooding is expected.

The River Forecast Centre says rises will begin in the North Coast regions on Tuesday and continue into Wednesday. Depending on rainfall, the advisory could continue through the end of the week and into the weekend.

The high water advisory stretches from Prince Rupert through the Nass, Stewart, Kitimat, Bella Coola and Bella Bella.
