Latest updates

  • Officials say 30 rescue events have taken place around Grand Forks
  • 2,700 residents affected by evacuation orders
  • 23 local states of emergency have been declared
  • More flooding expected next week as warm weather arrives
  • Kootenay Boundary and south Okanagan regions hit hard

Thousands of British Columbians remain under evacuation orders as warming temperatures combine with rain and melting snow to create historic flood conditions across wide areas of the province.

Most of the flooding is in the Southern Interior, including the Similkameen, south Okanagan and Kootenay Boundary regions, where residents are reporting floodwaters up to two metres deep.

One of the worst hit communities is the West Kootenay city of Grand Forks, where floods have reached historic levels.

The regional district says an unknown number of people are trapped in their homes, prompting a flyover by emergency officials on Friday.

A water rescue team has been deployed. As of Friday afternoon, the district reported over 30 rescues.

Water stood at least a metre deep in some downtown streets last night, shutting down Highway 3 through town to low clearance vehicles.

In the Okanagan region, flooding is also reported in the Cawston and Okanagan Falls areas, and in Osoyoos officials have ordered residents to immediately stop pumping any flood water into the sewers to avoid overwhelming the towns wastewater system.

Highway 8 was closed 10 kilometres west of Merritt after floodwater washed out the road. 

Warmer weather in forecast

CBC meteorologist Johanna Wagstaffe said the forecast is for a ridge of high pressure to build this weekend, pumping hot, dry air into the Interior.

"Temperatures for the weekend and Monday will be roughly five to 10 degrees above the seasonal average for the Southern Interior, hitting the 30s by next week," Wagstaffe said on Friday morning.

As the temperatures rise in the mountains a substantial amount of snow in the alpine areas is expected to start melting, bringing more flooding next week.

David Campbell, head of the British Columbia River Forecast Centre, said many areas across the province are nearing their flood record.

"It will be a gradual build over the next couple of days," he said. "In a number of areas, we're kind of near that cusp.… Is there enough snow to keep these rivers high?"

He said the snowpack in low elevation flood areas have melted, but mid-to-high elevation areas are still at risk.

"It's that in-between middle elevation zone that we're maybe a little bit uncertain of how this hot weather is going to influence things," he said.

More than 2,700 people under evacuation order

More than 2,700 people were affected by the orders, with many struggling to salvage what they could and fortifying their properties.

The Emergency Info BC website listed evacuation orders or alerts in seven regional districts and for eight First Nations around the province on Friday morning including:

The following communities have issued flooding-related Evacuation Alerts or Orders not currently available online:

  • Nazko First Nation
  • Nooaitch Indian Band
  • Westbank First Nation
  • Xat'sull First Nation (Soda Creek First Nation)

Flooding threat in Fraser Valley

Flooding is also a concern outside of the Interior.

The province encouraged local governments and First Nations communities along the lower Fraser River to prepare for potential flooding.

Public Safety Minister Mike Farthworth said the province is monitoring the water levels and has activated the South West Region Emergency Centre in Surrey.

"Even if temperatures cool, and we get additional rain, that can also aggravate soil and dikes that may be saturated," he said, adding that the province will roll out dike patrols starting next week.
