SALEM, Ore. (AP) — Oregon Gov. Kate Brown has declared a state of emergency because of the imminent threat of wildfires across the state. KOIN reports Brown says much of the state is in high or extreme fire danger with red flag warnings in effect. In the past week, a historic heatwave rolled through the Pacific Northwest, bringing high temperatures and worsening already dry conditions. Although the threshold of three-digit temperature days has passed, there is no rain in the extended forecast.
