Authorities on Tuesday designated a wildfire in southwestern Oregon as the top firefighting priority nationwide, a spokesman for the Incident Fire Management system said. Five homes have burned in the 153-square-mile (396-square-kilometer) blaze near Brookings, a coastal town near the California border, said Greg Heule, a spokesman for the team, which collaborates with various federal and state firefighting agencies and releases information about blazes around the country. The estimated containment date is October, according to officials.
