 Containment: 60% 

 General Updates: The National Weather Service has issued an “Excessive Heat Warning.”  Firefighters are well informed with extra guidance for heat-related illnesses, watch-out situation metrics and cooling tents to care for the firefighters during the anticipated record temperatures.  The footprint of the S-503 Fire remains the same.  Firefighters are continuing to mop-up areas of heat to the provided mop-up standards to create a cold, black rind around the fire’s edge. This buffer will secure the fire from moving out of the existing footprint.   Firefighting resources from the S-503 Fire assisted in a response to a new fire start yesterday, the B-270 Fire, on the Confederated Tribes of the Warm Springs Reservation. A variety of different firefighting resources are prepared to respond to new starts today. 

 Weather: Temperatures will continue to rise over the next several days to historic highs. Today will be sunny and hot with temperatures near 97 degrees in the lower elevations and 90 degrees around 3,200 ft. Minimum relative humidity is forecast for 20 – 25% with northeast winds 7-14 mph with gusts to 25 mph in the afternoon. Resources: 521 Total2–type 1 hotshot crews,5-type 2 initial attack crews, 5-type 2 hand crews, 2-camp crews, 2-heavy helicopters, 1-light helicopter, 38-engines, 6-dozers, 15-water tender, 4-skidgines, and 99 overhead.  

 Closures and Evacuations: Evacuation Level 1 – Get Set, as determined by the Wasco County Sheriff’s Office remains for all residences west of Kelly Springs Rd/Back Walters Rd plus anything east of Kelly Springs to Reservation Rd, including Walters Corners and the community of Pine Grove. 

 Temporary Flight Restrictions: For the safety of the firefighters and aircraft fighting the S-503 Fire, a temporary flight restriction has been placed over the fire area. Please consult the “Notice to Airman” for specifics. Wildfires are a “No Drone Zone.”
