July 14 lightning-strike fires
A number of fires were started by lightning strikes on July 14.
The Carlton Complex, covering 256,108 acres (400.2 sq mi; 1,036 km2), began as four separate lightning-caused fires on July 14 in the Methow River valley of Okanogan County: the Cougar Flat, French Creek, Gold Hike, and Stokes fires. These fires merged and rapidly spread southeast on July 17, burning approximately 300 homes in and around the towns of Pateros and Malott as well as in more rural areas.[4] The communities of Brewster, Carlton, and Methow were also threatened by fire. Power was lost to the communities of Twisp and Winthrop. Road closures included State Route 20 east of Twisp towards Loup Loup Pass, State Route 153 between Twisp and Pateros, and U.S. Route 97 between Pateros and Brewster.[5][6] Rain slowed the fire on July 24, allowing crews to reach 60% containment by July 26.[7] A new fire started along State Route 20 south of Winthrop on August 1.[6]
The Carlton Complex was the largest wildfire in Washington state's recorded history, surpassing the 1902 Yacolt Burn.[8] One death, caused by a heart attack, has been blamed on the fire.[8]Fire fighting efforts included nearly 3,000 personnel and numerous aircraft, including seven UH-60 Black Hawk helicopters from the Washington National Guard and a DC-10 Air Tanker.[7]
