Aug. 25 Air Quality Report for Rail Fire -- Weather and Smoke Synopsis

Weather: Today will remain stable and dry with a northly flow aloft.  Temperatures will be in the 70s, minimum relative humidity will be 15-24%, and winds will be light and terrain driven, except north winds on ridges gusting to 20 mph in the afternoon.  The inversion will lift around 9:00AM.  Tomorrow the flow will shift to northwest, then west on Saturday.  The weekend will be much warmer, drier, and windier.
Fire Activity: The fire is 47% contained at approximately 32,500 acres.   Patches of unburned fuel within the fire area continue to burn until consumed.  Mop-up of smoldering material continues on the west, north and east perimeters. The south flank of the fire remains active, as the fire moves slowly south within the Monument Rock Wilderness.  Again today, when conditions allow, containment lines will be strengthened with burnout operations. 
Smoke Summary:  Yesterday, smoke conditions were Good in all communities in the impact area.  Again today, Unity, John Day, Prairie City, Baker City, Vale and Burns will have Good conditions.  Smoke from fires in Idaho and Washington may contribute to haze in the area.  Expect smoke settling into the drainages overnight.
