What Does "Fire Weather Watch" Mean?
Think of it like a "heads up" — not an emergency yet, but conditions could become dangerous.
| Term | Simple Explanation |
|---|---|
| Fire Weather Watch | Critical fire conditions are possible in the next 12–72 hours. Stay alert. |
| Red Flag Warning | Critical fire conditions are happening now or very soon. Take action immediately. |
| Outflow Winds | Strong, gusty winds that rush out from a thunderstorm. They can spread flames fast. |
IMPORTANT: This is a Watch, not a Warning. But it could upgrade to a Red Flag Warning. Keep checking forecasts!
What Should You Do? (Step-by-Step)
- Stay informed – Check weather updates Thursday morning and afternoon.
- Avoid outdoor burning – No campfires, debris burning, or fireworks in watch areas.
- Secure loose items – High winds can turn patio furniture, tarps, or tools into hazards.
- Prepare your vehicle – Keep gas tank full; pack water, snacks, and a charger in case of evacuation.
- Review your family plan – Know two ways out of your neighborhood. Pick a meet-up spot.
- Sign up for alerts – Register for local emergency notifications (e.g., CodeRED, Nixle, county alerts).

FAQ
What’s the difference between a Watch and a Warning?
A Watch means dangerous conditions might happen. A Warning means they are happening or will soon. Think: Watch = "Get ready." Warning = "Go!"
Why only above 3,000 feet?
Higher elevations are drier, windier, and have more lightning-prone thunderstorms — a risky combo for fire.
What are "dry thunderstorms"?
Storms that produce lightning but little or no rain. Lightning hits dry grass/trees → fire starts. Wind fans the flames.
I live in one of these counties but below 3,000 ft. Am I safe?
The watch doesn’t cover you, but fires can move downhill fast. Stay aware regardless.
