What is a red flag warning?
A red flag warning means critical fire weather is happening or about to happen: strong wind, very low humidity and dry fuels together, so a fire that starts can spread fast. Each office sets the criteria with its land-management partners. A warning means the hazard is happening, about to happen, or very likely: act now to protect people and property.
