Wildfire smoke shows up in air-quality data as fine-particle (PM2.5) pollution — it’s the number that climbs when smoke moves in. A Fire Weather Watch from the National Weather Service means critical fire-weather conditions — dry fuels, low humidity, gusty wind — are possible in the next day or two; a Red Flag Warning means they’re happening or imminent. On smoky days, EPA and AirNow guidance is to limit time outdoors, keep windows closed, run filtration if you have it, and wear an N95 if you must be outside.
