High Alert: Hagen Fire Triggers Level 3 Evacuations and Rare PDS Red Flag Warning in Union and Umatilla Counties, Oregon
A severe and rapidly escalating wildfire emergency is gripping northeastern Oregon. As of August 1, 2026, the persistent Hagen Fire—burning across high-elevation timber and rugged terrain between Union and Umatilla counties—has forced local emergency management to issue urgent warnings, mandatory evacuation orders, and strict travel advisories.
Compounded by soaring summer temperatures, bone-dry fuels, and a rare Particularly Dangerous Situation (PDS) Red Flag Warning issued by the National Weather Service (NWS), officials are urging residents and travelers in the path of the blaze to act immediately.
Fast Facts: The Hagen Fire & Regional Hazards (August 1, 2026)
Incident Name: Hagen Fire
Impacted Regions: Umatilla County and Union County, Oregon (including areas near Tollgate, Spout Springs, Langdon Lake, and regional forest boundaries).
Core Weather Hazards: A rare Particularly Dangerous Situation (PDS) Red Flag Warning in effect from 11:00 AM to 11:00 PM on August 1, featuring high winds, low relative humidity, and extreme fire growth potential.
Evacuation Status: Mandatory Level 3 (“Go Now!”) orders active in designated zones; Level 2 (“Be Set”) and Level 1 (“Be Ready”) warnings in surrounding areas.
Travel Restrictions: The public is strongly urged to avoid unnecessary travel on Highway 204 to keep routes clear for emergency responders and evacuees.
Issuing Agencies: Umatilla County Sheriff’s Office, Umatilla County Emergency Management, Union County Sheriff’s Office, Confederated Tribes of the Umatilla Indian Reservation (CTUIR), and Northwest Incident Management Team 7.
The Threat Escalates: PDS Red Flag Warning and Extreme Weather
What makes this flare-up particularly critical is the meteorological backdrop. The National Weather Service has upgraded standard fire weather alerts to a Particularly Dangerous Situation (PDS) Red Flag Warning for August 1.
A PDS designation is rare—reserved for events meeting or exceeding the 95th percentile of fire-weather severity. Emergency officials emphasize that this is not a routine Red Flag Warning. The combination of strong, gusty winds, extremely dry vegetation, and sustained high temperatures creates an environment prone to:
Explosive and Unpredictable Fire Behavior: Rapid rates of spread and long-range spotting that can easily outpace initial suppression efforts.
Drastically Reduced Visibility: Heavy smoke, blowing dust, and ash choking regional roadways.
Compromised Infrastructure: Potential power outages, falling tree limbs, and downed power lines that can block evacuation routes without warning.
Evacuation Orders: Level 3 “Go Now!”
Local authorities have made it clear that time is of the essence. Residents located within Level 3 (“Go Now!”) evacuation zones must evacuate immediately.
Do Not Wait: Officials warn residents not to wait until Saturday afternoon, until they see flames, or until emergency alerts force their hand. Once extreme winds arrive, conditions can deteriorate so rapidly that emergency responders may be unable to safely enter the area to render assistance.
Highway 204 Advisory: The public is instructed to avoid non-essential travel on Highway 204 through Tollgate, Spout Springs, and Langdon Lake. This critical corridor must remain open and free of congestion for evacuating residents, fire engines, water tenders, and heavy equipment.
Pre-Evacuation Zones: Residents in Level 2 (“Be Set”) and Level 1 (“Be Ready”) zones should complete their preparations now—keeping vehicles fueled, mobile devices charged, and emergency go-bags packed. Those with medical needs, children, pets, or livestock are strongly encouraged to leave early rather than risk getting trapped by sudden wind shifts.
Essential Wildfire Safety & Evacuation Checklist
When fast-moving wildfires and extreme weather threaten your community, preparation and decisive action save lives. Follow these vital safety protocols:
Heed Evacuation Orders Instantly: If local authorities or emergency management tell you to evacuate, do not delay. Gather your emergency go-bag, essential medications, pets, and important documents, and leave immediately via designated safe routes.
Avoid Highway 204 Unless Evacuating: Refrain from sightseeing or non-essential travel in the Tollgate and surrounding backcountry areas to keep roadways clear for firefighting personnel.
Protect Your Respiratory Health: Thick smoke from the Hagen Fire and regional blazes is severely degrading local air quality. Keep windows and doors tightly sealed, and utilize HEPA indoor air filtration systems if you are outside the immediate evacuation footprint.
Stay Informed via Official Channels: Keep a battery-operated or NOAA weather radio tuned to emergency frequencies, and continuously monitor real-time evacuation maps provided by Umatilla and Union County Emergency Management, Oregon’s RAPTOR mapping tool, and Watch Duty.
Report Emergencies Promptly: Stay away from downed power lines and call 911 immediately if you encounter an active, life-threatening hazard.
