More evacuations ordered as flood warnings expanded in B.C.'s Fraser Valley

B.C. Officials feature expanded glut warnings and issued reinvigorated evacuation alerts in the southern component of the responsibility as river levels remain high — and continue to rise in some places — after an atmospheric river hit the region.

Much of the Fraser Valley remains under a flood warning on Thursday, but new warnings have been issued for Princeton and other areas along the upper Similkameen and Tulameen rivers and their tributaries.

Environment and Climate Change Canada lifted heavy rainfall alerts on Thursday — after areas of the Fraser Valley, including Abbotsford, Chilliwack and Hope, were hammered by an intense downpour for 24 hours.

But flooding risk remains for local rivers, including those flowing across the Canada-U.S. Border — such as the Nooksack — that continue to swell from the influx of water.

Floodwaters in Sumas Prairie and Huntingdon Village are expected to peak within the next 12 hours, according to the City of Abbotsford.

The city says water levels on the Abbotsford side of the border continue to rise and based on modellings and data taken after floods in 1990, water is anticipated to reach Highway 1 late Thursday evening or early Friday morning.

The City of Abbotsford has issued new evacuation orders for seven properties north of Highway 1, including the Clarion Hotel and the Ministry of Agriculture and Food building, as rising floodwaters continue to spill onto the highway.

City officials say the flooding has forced the closure of Highway 1 in both directions between Sumas Road and Whatcom Road. Drivers are being asked to avoid the area and check DriveBC for updates as conditions continue to change.

The city had declared a state of local emergency Wednesday night, putting 371 properties in the Sumas Prairie area under evacuation order, while a further 1,069 properties remain on evacuation alert.

It had expanded its evacuation orders earlier Thursday to include an additional 82 properties in Huntington Village.

The Clayburn Village evacuation alert has since been lifted.

The Regional District of Okanagan-Similkameen declared a state of local emergency on Thursday evening as water levels rose in several rivers in its jurisdiction. 

The district has further issued evacuation orders for two properties close to the Similkameen River in Princeton, B.C. Along Highway 3.

Orders are also in place for the Chopaka electoral area in rural Cawston B.C., an unincorporated community southeast of Princeton. It isn't clear at this time how many properties have been affected by this order.

An evacuation order for the Princeton Municipal Campground is now in place area due to rising water. The district is urging anyone in the area to leave immediately.

DriveBC has updated its list of highway closures and reopenings after all major routes out of the Lower Mainland were closed on Wednesday.

The following major highways are still closed as of 9:45 p.m. PT:

These highways have been fully or partially reopened:

Dave Campbell with the B.C. River Forecast Centre says up to 150 mm of rain has fallen since the atmospheric river made its way into the region Tuesday night.

A summary from Environment Canada says 140 millimetres of rain fell at the Hope airport on Wednesday, 125 mm at Cultus Lake and 110 mm at the Chilliwack airport.

Campbell says another atmospheric river is expected to bring more rain to the region, but it was unclear at this point if it would further affect the current flood situation.

There have been no reports so far of catastrophic flooding like what was seen in 2021, but officials say that could still occur.

"Fingers crossed that things are going to be OK for us out here."

Campbell said it will be well into Thursday evening before water levels in Washington state rivers drop enough that they stop pushing excess flow north into Canada.

"The impacts of that could really persist through the evening and into tomorrow," he said.

B.C. Officials provide update on Fraser Valley flooding

Washington state was under a state of emergency Thursday morning from a barrage of torrential rain that has sent rivers flowing over their banks, caused a mudslide to crash down on a highway and trapped people in floodwaters.

Tens of thousands of residents could face evacuation orders there, according to local officials.

After days of seemingly unrelenting heavy rain, Gov. Bob Ferguson declared a state-wide emergency Wednesday night, warning "lives will be at stake in the coming days.”

Some residents have already been ordered to higher ground, with Skagit County, a major agricultural region north of Seattle, ordering those within the Skagit River’s floodplain to evacuate.

Amtrak trains between Seattle and Vancouver have been suspended.

Flood watches and high streamflow advisories are also in place across much of the southern portion of B.C.
