Fire Weather Alerts
& Red Flag Warnings
StormCast delivers NWS Red Flag Warnings and Fire Weather Watch alerts directly to your phone when conditions favor rapid wildfire spread — so you can prepare before fire weather arrives.
Fire Weather Alert Types
Red Flag Warning
Critical fire weather conditions are occurring or imminent. Low humidity, strong winds, dry fuels. Any fire that starts will spread rapidly and be difficult to control. Avoid all outdoor burning.
Fire Weather Watch
Red Flag conditions are possible in the next 12–72 hours. Prepare now — clear brush near structures, review evacuation routes, avoid burning debris.
What Triggers a Red Flag Warning
Strong Winds
Sustained winds of 25+ mph with gusts higher. Wind drives fire spread and makes containment nearly impossible.
Low Humidity
Relative humidity below 15%. Vegetation dries out rapidly, creating fuel that ignites easily from any spark.
Dry Fuels
Extended periods without rain leave grass, brush, and forest litter tinder-dry. Even a cigarette butt or trailer chain spark can start a wildfire.
Dry Lightning
Thunderstorms that produce lightning but little or no rain. Each strike can ignite a new fire in dry terrain with no rain to slow it.
