Officials say a half-inch of rain fell on the Whisky Creek Fire southeast of Cascade Locks overnight, which is helping containment efforts.  But Northwest Complex Incident Management Team 10 Operations Section Chief Cary Neu points out that even with that amount of precipitation, these rains will not put out the fire, thanks in part to the heavy tree canopy.  Containment of the fire remains at 24%, with the acreage at 2,067.  Crews on Thursday successfully constructed over half a mile of new fireline near Tomlike Mountain, and are now focusing on reinforcing existing containment lines.
