Red Flag Warning Issued for Parts of California, Nevada, and Arizona

June 25, 2026 · wweather1 editorial · 2 min read

The National Weather Service in Las Vegas has issued a Red Flag Warning for portions of southeastern California, southern Nevada, and northwestern Arizona. This warning is in effect from Friday morning, June 26, through Saturday evening, June 27.

The National Weather Service (NWS) in Las Vegas has issued a Red Flag Warning for parts of southeastern California, southern Nevada, and northwestern Arizona. The warning is in effect from 11 AM PDT / 11 AM MST on Friday, June 26, through 11 PM PDT / 11 PM MST on Saturday, June 27. This replaces a previous Fire Weather Watch for the region.

Areas under the warning include Lake Mead NRA/Colorado River-AZ side, Northwest Deserts/Northwest Plateau, Death Valley National Park, Mojave Desert Including Morongo Valley/Yucca Valley, Lower Colorado River Valley, Esmeralda and Nye County Deserts/CNC Dispatch, Lincoln County/Ely Dispatch, and Nye County Deserts/Las Vegas Dispatch. Forecasted conditions include southwest winds ranging from 20 to 30 mph, with gusts up to 40 to 50 mph. Humidity levels are expected to be low, between 5 and 15 percent.

A Red Flag Warning signifies that critical fire weather conditions are either occurring or will occur shortly. The combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior. Any fires that develop under these conditions will likely spread rapidly. Outdoor burning is not recommended during the warning period.

Why it is dangerous and what to do

⚠️ Safety
• Do not conduct outdoor burning.
• Exercise extreme caution to prevent new fire ignitions.
• Monitor official weather alerts and local fire information.
• Prepare an evacuation plan if in fire-prone areas.
