    Sedro Woolley, WA – With cooler temperatures, higher humidity, and light rains over several days, the Sourdough Fire has had minimal growth and low areas of heat. The fire remains at 6,234 acres with 25% containment.  
    Firefighters continue to monitor for fire spread on the western flank near the 2015 Goodell burn scar and on the eastern flank in the Sourdough Creek drainage. Crews will utilize aviation resources as necessary. Fire behavior is expected to remain minimal over the next few days with continued cloud cover and low temperatures. A slight chance of rain is possible for Wednesday; no significant or wetting rains are anticipated with this system. Warmer and dryer temperatures are expected nearing the weekend.
