The National Weather Service issued a “critical fire weather” warning for the end of this week across much of Arizona. The forecast calls for 10% to 15% humidity, 40 mph winds and extremely low fuel moisture.
The critical conditions hit the desert areas early in the week, with the fire warning spreading into the mountains at the end of the week — including much of New Mexico.
“A fire weather watch means that critical fire weather conditions are forecast to occur,” said a National Weather Service bulletin. Listen for later forecasts and possible red flag warnings. Dry fuels will be highly susceptible to ignition and spread. Mountain zones will be slower to reach critical RH due to cooler temperatures, though windy conditions still present the risk of fire spread.”
