Fire officials say a lightning-sparked wildfire burning about 10 miles north of Ellensburg, Washington, has destroyed more than a dozen structures, including six homes or cabins, and threatens dozens of other homes.

The Kittitas County sheriff's office has issued its most serious evacuation notice for about 80 homes. The sheriff's office said late Monday that 16 structures are confirmed lost, including six residences or cabins.

Fire spokeswoman Sarah Foster says the Snag Canyon Fire that started late Saturday has scorched about 3 square miles of grass, brush and timber. It's about 10 percent contained and 200 firefighters are attacking it.

Foster said after a quiet afternoon, the wind was "starting to rattle the trees" Monday evening.

In north-central Washington, about 1,700 people are battling Washington state's largest wildfire, which has destroyed about 470 structures since it started July 14.

Fire spokesman Steve Till says the Carlton Complex of fires, which has scorched nearly 400 square miles, is 90 percent contained. Firefighters have built a line around a nearby fire that started Friday between Twisp and Winthrop and burned a handful of homes, but Till says it's not considered fully contained.
