Schools closed, power lines down as B.C.'s South Coast hit with freezing rain

A storm on B.C.'s South Coast Thursday iscausing treacherous road conditions throughout the Lower Mainland and on southern Vancouver Island.

The Port Mann Bridge was temporarily closed for de-icing but has since reopened.

In Metro Vancouver, Environment Canada has changed what began as a winter storm warning to a rainfall warning, with up to 20 millimetres of rain expected today.

Environment Canada is also calling for up to 50 millimetres of rain in Squamish, and as much as 40 centimetres of snow north toward Whistler.

In the Lower Mainland, where temperatures are warmer, pooling water is starting to become an issue.

Robert Costanzo, Surrey's manager of engineering operations, said there are at least six locations throughout the city with up to six inches of water on major roads.

"It's really a race to clear out catch basins and areas where we have any packed snow or ice," Costanzo said.

Icy roads in the Fraser Valley

In theFraserValley, freezing rain made already slippery roads even worse.

In the Sumas Flats area of Abbotsford, single lane roads were covered in ice after the overnight storm.

Abbotsford Police issued a warning to drivers late Wednesday night of a number of road closures in this area.

Drive BC is cautioning drivers against travelling along Highway 1 between Hope and Langley today due to freezing rain.

Drive BC is also warning of poor driving conditions on Vancouver Island, reporting pooling water on the Trans-Canada Highway and snow-covered highways north of Duncan.
