West Kelowna wildfire grows to 400 hectares

B.C. firefighters said Friday morning they are having some success in battling a forest fire that has forced the evacuation of 1,100 homes in the central Okanagan, even though the blaze continues to grow.

The Smith Creek fire outside West Kelowna, which had scorched 250 hectares as of Friday morning, is reportedly 20 per cent contained — but, as of noon, it has also grown to 400 hectares.

Fire information officer Kayla Pepper said crews were aided by calm winds overnight, but conditions are expected to change later today and winds are forecast to reach gusts of 40 km/h.

"Firefighters are on the front line, we're bringing in additional resources this morning, and emergency services are in place" said Forests Minister Steve Thomson. "This is a community that has experienced this before and a community that rallies around and steps up to the plate."

Crews from West Kelowna, Peachland, Kelowna, Lake Country and the B.C. Forest Service are actively working to guard property and public infrastructure.

Residents who haven't been asked to leave their homes are being warned to prepare for possible power outages.

BC Hydro said the fire is burning within 100 metres of its main feeder line, which serves Peachland, Westbank, and West Kelowna.

West Kelowna Mayor Doug Findlater said if flames reach the power line, the communities will be completely unplugged.

"I'm very nervous about it," he said. "It's distressing too in the sense that firefighters now vitally have to protect that as well as structures and homes."

The line provides power to more than 60,000 people, and there is no backup.

BC Hydro said power would only be restored once the line is repaired, adding residents should be prepared for a lengthy outage.

"We do encourage customers to have an emergency kit ready, things like flashlights, batteries, bottled water," advised Mora Scott, BC Hydro spokeswoman.

The Wildfire Management Branch is applying fire retardant on the line's right of way in efforts to protect the power source.

Map: West Kelowna evacuation areas 

More than 2,500 residents from 1,100 homes spent last night out of their homes after an evacuation order was expanded Thursday.

Another 150 homes along and near Lenz Road, including the Pinewood Villa Mobile Home Park and from 1898 to 2515 Bartley Road, were put on evacuation alert at around 8:30 p.m. PT. Residents there were told to be prepared to leave their homes at a moment's notice.

West Kelowna's mayor and council also declared a local state of emergency in the municipality of 31,000 residents.

The initial order Thursday afternoon, shortly after the fire broke out, affected only about 200 residents, but was quickly expanded to 1,500 residents in 585 homes before nearly doubling again at 7 p.m. PT. Thursday.

The fire, which was half a hectare when first reported, expanded within hours to 30 hectares, and by Thursday night emergency officials said it had grown to 200 hectares. By Friday morning, it had grown to 250 hectares.

It was burning in the hills behind Smith Creek and Dixie Roads, threatening homes in the neighbourhood immediately below it.
