Management of the Alder Creek Fire in Wheeler County will transition to local resources Tuesday morning.  Central Oregon Fire Information says rain showers and cooler temperatures this morning passed through the fire area.  The fire remains at 1,550 acres and is now 50% contained.  Local resources will remain on the incident, mopping up hot spots closest to the fires edge.  Occasional torching trees and pockets of fuels within the fire perimeter will continue to burn and create smoke.  Oregon Route 19 that parallels the northern edge of the fire area is now open.         There is still potential for the road to be closed at any time if fire activity deems necessary.  Cause of the fire remains under investigation.
