Floods, mudslides and avalanches close B.C. highways

More rain is forecast for southern B.C. by Wednesday night as the region struggled through a combination of heavy downpour and melting snow, leading to flooding, mudslides and avalanches that closed several major highways.

Coquihalla Highway, the main route between Vancouver and the Interior of the province, is closed indefinitely after all four lanes in both directions were covered by a mudslide near Hope on Wednesday around 10 a.m. PT.

Highway crews were assessing the slide Wednesday afternoon to determine the slope stability, said Jeff Knight, a spokesman for the Ministry of Transportation.

"And of course there would be cleanup involved in removing the debris off the highway so at this point we don't have an estimated opening time," Knight said.

Meanwhile, eastbound traffic on the alternative route on Highway 1 was being diverted near Hope and Laidlaw because of an earlier mudslide.

The area had received an estimated 120 millimetres of rain since Tuesday morning and was forecast to receive up to another 80 mm by Wednesday night.

Further east, Highway 1 was closed between Craigellachie, Revelstoke and Golden due to high avalanche danger.
Kootenay and Sooke highways closed

Several highways in the Kootenays were also closed because of the severe weather, including Highway 6 near Slocan because of an avalanche, Highway 3 and parts of Highways 23, 31 and 31A, all due to high avalanche risks.

Road crews were assessing the danger and the routes will remain closed until it's safe to drive them, said Fred Hughes, an operations manager with the Ministry of Transportation.

"We have avalanche technicians attending the scene to assess whether they're able to remove the snow through heli-bombing, which is dropping little charges out of a helicopter, or if they're not able to do that, making sure the site is secure and the public is not going through there," Hughes said Wednesday afternoon.

Road access to the southern Vancouver Island community of Sooke was shut down after both Highway 14 and East Sooke Road flooded overnight. Crews and volunteers worked through the night sandbagging and clearing culverts.

Officials in the Sooke school district said most schools will not be closed, although many bus routes will not be running and schools will be short-staffed. Parents were encouraged to keep their children home.

There have been no reports of deaths or injuries related to the highway closures.
Flooding in Fraser Valley

There was heavy flooding in parts of the Fraser Valley Wednesday afternoon, and Chilliwack appears to be the hardest hit, said Glen McPherson, the city's director of public works.

The Fraser Valley has received more than 150 mm of rain over the past 24 hours.

About 40 homes have flooded basements as a result of heavy rain coupled with melting snow, McPherson said.

"Most of the drainage ditches on the valley floor around Chilliwack are full to bursting and many of them have started overflowing banks," he said.

"And we're experiencing localized flooding on the roads and some private properties have started having water enter the basement."

Residents were being warned to keep storm drains around their property clear and watch for signs of flooding.
More rain forecast

With heavy rain forecast to continue until Thursday in the south of the province and heavy snow forecast for the central Interior, weather warnings were issued by Environment Canada for many areas.

Between 40 and 80 mm of rain fell on parts of Vancouver Island, Metro Vancouver and the Fraser Valley since the rain began melting snow on Tuesday morning, and the forecast was for another 40 to 80 mm by Wednesday night.

In Vancouver road crews spent the night repairing large potholes on the Oak Street Bridge, but most transit was running normally except for bus routes 210, 320 and 395, which were being rerouted to avoid flooded areas.

Provincial officials issued an advisory that south coast rivers were expected to have high water levels, but none was forecast to lead to major flooding.

Across the province, more than 9,000 BC Hydro customers lost power on Wednesday morning for various reasons, including residents of Hope, Duncan, Pemberton, Salmon Arm, Sicamous, Vernon, Nakusp, Cranbrook and Prince Rupert.
