The number of evacuees was climbing as fast as the flood waters in towns north of Vancouver, B.C. Sunday. The worst rainstorms in a century have deluged the region, claiming two lives and sending some 800 people to higher ground.

After doing a flyover of the area Sunday, British Columbia Solicitor General Rich Coleman said two people had been confirmed dead and two others were missing.

They were swallowed up by a river south of Pemberton when it burst its banks and washed out a bridge.

"There's a lot of devastation," Coleman said. "The washout that took place was sudden and fast."

One body was found in a jeep and another vehicle, a red SUV, believed to have been carrying three people, was still missing.

Helicopter crews spotted a vehicle in the water but couldn't positively identify it. An intensive search will be carried out once water levels subside.

There was a break in the weather Sunday after days of relentless rain, but only enough for residents of Pemberton and Squamish to catch their breath before the next downpour, expected Monday.

"We're expecting heavy rain overnight and rain every day for the next five days," said Bob Bugslag, director of the Provincial Emergency Centre in Victoria.

In the last three days, parts of southwestern B.C. have been deluged by record 350-millimetres of rain. A state of emergency was in effect for Pemberton and Squamish.

Bugslag said officials were focused on getting supplies to people in Pemberton, adding no food had been delivered to the town of 10,000 since Friday due to washed out bridges.

But, Pemberton Mayor Elinor Warner told CTV Newsnet residents were working to take care of each other.

"The community has responded. We've got people calling to volunteer. People making sandwiches. We have an evacuation centre set up and there is about 155 people registered at that now. We have sandbagging being done at some points," Warner said.

Most residents were upbeat Sunday, ready to battle through the storms.

"There's no shoving in line at the drug store or the grocery store. I don't think there's any panic that we're going to starve or go without things we need," Grace Jones, a resident at a Pemberton seniors' complex, told The Canadian Press.

Farmers have been working for days to move livestock, but some had to leave themselves before the job was done.

Evacuees were staying primarily with friends or at hotels throughout the region.
