Western US Wildfires Continue to Rage VOA News WASHINGTON - Wildfires continued to rage across large swaths of the Western U.S. on Sunday, with massive clouds of smoke enveloping the region and endangering the health of millions of residents. Air quality across the Pacific Northwest state of Oregon was characterized by state environmental officials as "hazardous" or "very unhealthy." Dense smoke warnings were posted in Oregon and the neighboring state of Washington by the National Weather Service. In all, throughout the Western U.S., there were 24 fires in California, 15 in Washington, 14 in Oregon, 12 in Idaho and others in Alaska, Arizona, Colorado, Nevada, New Mexico, Utah and Wyoming. The blazes have killed at least 10 people in Oregon, with emergency workers expecting the death toll to increase. Some people in Portland, the state's largest city, and elsewhere were fighting for breath as smoke filled the air. The fires have ravaged more than 400,000 hectares of land in the state. .
