Air support helped to knock down a brush fire along Interstate 84 at milepost 76 near Rowena.  A helicopter and water dropper based in Dallesport and two air tankers out of Redmond made significant progress on the fire detected around 10:45 Friday morning.  The fire led to traffic delays through the area on Interstate 84, and the Wasco County Sheriff’s Office issued evacuation advisories in the area of the Historic Columbia River Highway, Rowena River Road, and Mayer State Park.  As of early this afternoon the aerial support were returning to their bases, while firefighters from numerous area agencies were doing mop-up.  There was the potential for more freeway delays while that work takes place.
