red flag warnings
Severe fire advisories
Red flag warnings are official alerts issued by weather services when conditions are extremely favorable for wildfire ignition and rapid spread—typically a combination of low humidity, high winds, and dry vegetation.
The term comes from the literal red flags once used to signal fire danger: A red flag warning is in effect for the foothills through Tuesday.
During such warnings, authorities may restrict outdoor burning and urge heightened caution.
