Highway closures, evacuation orders across B.C. Interior due to flooding, mudslides

A "rapid transition'' into spring with a week of record-setting temperatures has accelerated mountain snowmelt, a provincial forecaster said, leading to flooding and mudslides throughout British Columbia's central and southern Interior.

Dave Campbell, head of B.C.'s River Forecast Centre, said the problems will be compounded by heavy rains and possible thunderstorms expected this weekend.

"This is really going to add additional run-off to the rivers that are already high from the snowmelt. So, in areas where we already have issues related to flooding, we do anticipate we could see exacerbation of those conditions,'' he told a news conference hosted by the Ministry of Emergency Management on Thursday.

"We can also expect to see new areas coming online as rivers are challenged with additional run-off coming from the snowmelt and rainfall.''

Rising river levels forced the evacuation of several homes and properties in Cache Creek as water flooded the streets.

Flood warnings, lower-level flood watches or high streamflow advisories cover much of the province's southern and central Interior.

The B.C. government has said conditions in areas that are currently flooding, including Cache Creek and theOkanagan Indian Band territory, were expected to deteriorate, while "moderate flooding'' was likely in Grand Forks starting Friday.

"Unfortunately, it is likely that some of these communities are going to see conditions get worse in the immediate short term before they get better,'' Emergency Management Minister Bowinn Ma told media on Thursday.

Sandbags and other barriers have been deployed to communities that are at risk, she said.

Ma said the province is aware of seven evacuation orders and six evacuation alerts across B.C., but warns that "it is a dynamic situation that is quickly evolving.''

'Unbelievable' amount of water: Cache Creek mayor

The number of properties under evacuation order in Cache Creek ticked up to 13 from five on Wednesday. Mayor John Ranta said one home is likely lost.

To the east, the Okanagan Indian Band has expanded an evacuation order for properties along Okanagan Lake in the community of Parker Cove, where it says floodwaters from Whiteman Creek have eroded land and undercut trees.

It was "unbelievable the amount of water'' that was flowing over Highway 97 and down Highway 1 as the two routes intersect in the village west of Kamloops, Ranta said in an interview on Thursday.

The CBC's Brady Strachan saw the significant damage from the gushing of Whiteman's Creek at Parker Cove, near Vernon.

Many businesses have been devastated by the flooding, and the floodwaters are running through the firehall, he said.

The mayor said he's spoken with Emergency Management Minister Bowinn Ma, who offered support from the province, and several B.C Wildfire Service crews are in the village to help distribute sandbags.

But Ranta says there's nothing they can do until the waters recede.

Record-high temperatures

Temperature records were broken in 10 B.C. communities on Wednesday, including several where flooding is a risk. Yoho National Park reached 25.3 C, more than three degrees above the record setback in 1923.

Environment Canada says rain, at times heavy, is also moving in across the southern Interior on Friday and through the weekend.

A statement from the B.C. government says conditions in areas that are currently flooding, including Cache Creek and Okanagan Indian Band territory, were expected to deteriorate, while "moderate flooding'' was likely in Grand Forks starting Friday.

An update posted on the Grand Forks website says local fire crews were working on a temporary dam nearly 460 metres long to protect one of the areasmost vulnerable to flooding in the community near the Canada-U. S. border.

Grand Forks is in the Regional District of Kootenay Boundary, which has declared a state of local emergency and issued an evacuation order for 10 propertiesas water levels rise on the Kettle River.

Grand Forks Mayor Everett Baker said Thursday his community has been preparing for the wet weather expected this weekend.

Baker said the city has received temporary dams, sandbags and other assets from the province to prepare for flooding, with past events top of mind after Grand Forks lost nearly 100 homes to rising waters back in 2018.

He said crews are concentrating efforts to protect homes, businesses, and infrastructure in the city's downtown, while properties in the outlying areas are harder to support, and those living there are aware they are on a floodplain.

Baker said his daughter lost her home in the last major flooding event, so he's keenly aware of the stress of another potential disaster.

"That's why I know myself and council and our city staff decided this time that we were going to try to be as proactive as possible and get out the protection that we can sooner than later,'' he said. "Then, hopefully we'll have done enough to protect the city.''

The Regional District of Central Kootenay has put three more properties on evacuation alert in response to a landslide and debris flowing from Talbot Creek in the community of Vallican, where photos shared by the district show the water has carved a deep channel through Little Slocan South Road.

Highway closures, delayed sailings

Another mudslide forced the closure of an 80-kilometre stretch of Highway 3 between Salmo and Creston. The stretch of road has re-opened, DriveBC said around 5 p.m. Thursday.

A stretch of the Kootenay Pass onHighway 3 was closed in both directions about 15 kilometres east of Salmo due to flooding. It has since opened to single-lane alternating traffic, DriveBC said early Thursday evening.

Passengers on the Kootenay Lake ferry face a one-sailingwait between Balfour and Kootenay Bay due to the Kootenay Pass closure, DriveBC said.

Meanwhile,a short stretch of Highway 99 is closed due to flooding about 67 kilometres north of Lillooet, with assessments underway in both areas.

Heading into the weekend, the province's statement issued late Wednesday says, "Significant flood hazard is expected throughout small and medium-sized watersheds in the Central Interior, Okanagan, Boundary and Southern Kootenays.''

It says sandbags and other barriers have been deployed to at-risk communities, and people in affected areas are encouraged to make household emergency plans.

The City of Penticton says it has set up a sandbag station as a precautionary measure, saying water levels in Penticton and Ellis creeks have risen, but officials are confident the creeks and surrounding lakes will be able to absorb the water.
