Red-flag fire warnings are in effect across parts of five Western states as hot, dry, and windy conditions raise the risk of extreme wildfire behavior, the National Weather Service (NWS) reports.
Why This Matters
Red-flag warnings alert residents when wildfire conditions are at their most dangerous—high heat, dry air, and strong winds can cause fires to ignite and spread rapidly. Much of the western U.S. has endured long-term drought, leading to severe fire seasons. Just this year, wildfires in Southern California caused multiple deaths and destroyed homes near Los Angeles.
Where Are Red-Flag Warnings in Effect?
As of Monday, parts of Colorado, Idaho, Nevada, Utah, and Wyoming are under red-flag warnings. The warning covers:
-
Most of Utah
-
Western areas of Colorado
-
Southwest Wyoming
-
Southeast Idaho
-
Central and northern Nevada
These regions face critical fire conditions driven by:
-
Strong southwesterly winds (gusts up to 35 mph in Utah)
-
Low relative humidity (as low as 5% in some areas)
-
Warm temperatures and dry fuels
Some areas in central Nevada are under a Fire Weather Watch, meaning dangerous fire weather is possible soon.
What Residents Should Do
During red-flag warnings, the NWS urges residents to:
-
Avoid campfires, fireworks, and outdoor burning
-
Refrain from smoking outdoors
-
Have a wildfire evacuation plan ready
-
Keep a go-kit in case of emergency
-
Stay alert to local evacuation orders and updates
What Officials Are Saying
-
NWS Salt Lake City, on X:
“Southwesterly winds with gusts to 35 mph will combine with low RH to create critical fire weather conditions Monday through Wednesday for much of Utah.” -
NWS Elko, Nevada, on X:
“Elevated wildfire risk in northern and central Nevada from 11 AM to 10 PM today. Dry fuels, low humidity, and gusty winds can lead to extreme fire behavior.”
What’s Next
The warnings will remain in effect through 9 p.m. MT on Wednesday in areas around Salt Lake City and possibly longer in other regions depending on weather developments.
Stay prepared, stay safe, and follow updates from the National Weather Service and local emergency officials.
