SPOKANE, Wash. (AP) — The largest wildfire in Washington state history grew by more than 22 square miles overnight, and firefighters are worried about high winds predicted for this weekend.

The Okanogan Complex of wildfires was listed at 472 square miles on Friday morning, after windy conditions Thursday pushed the fire on a couple of runs. It is only 12 percent contained.

Officials say the fire has destroyed at least 45 primary residences, 49 cabins and 60 outbuildings. Three firefighters died battling the fire last week, and a memorial service for them is planned for Sunday in Wenatchee.

Fire spokeswoman Sierra Hellstrom says temperatures are lower and humidity higher on Friday, which is good news for firefighters. But thunderstorms with high winds predicted for this weekend could fan the flames.
