NCW — Stiff winds on Thursday caused a small wildfire in the Lake Chelan Sawtooth Wilderness to grow from 2 to 10 acres.
The Sun Mountain Fire, burning in the south fork of War Creek, is about 15 miles southwest of Twisp, and is not close to Sun Mountain Lodge near Winthrop.
Six smokejumpers were joined by 10 firefighters from the Methow Valley Ranger District, and are assisted by helicopters dropping water, said fire spokeswoman Shannon O’Brien. The fire was caused by lightning Sunday, and was detected on Tuesday.
Firefighters are also working to contain two other fires near Lake Chelan.
Firefighters on the lightning-caused Twin Harbor Fire had to disengage from the fire for a period on Thursday due to the winds, said fire spokeswoman Elka Missal. But winds did not cause the blaze to grow beyond its perimeter. It’s still about 4 acres, and is burning about 35 miles northwest of Chelan, on the lake’s south shore.
Missal said winds did not affect the 2,098-acre 25 Mile Fire northwest of Manson. That fire is mostly in mop-up stage, and there was very little smoke from the blaze on Thursday, she said.
The cause of the fire burning northwest of Manson since July 4 is still under investigation.
Winds will not be as gusty today, although calm weather is not in the forecast until next week.
“We’re going to remain breezy throughout the weekend,” said Ryan Fliehman, meteorologist for the National Weather Service.
He said only a slight chance of thunderstorms is in the forecast for areas of the North Cascades, close to the Canadian border.
