Fire weather watch
A fire weather watch means critical fire weather — strong wind, low humidity, dry fuels — could develop in the next 12 to 72 hours. It's the heads-up before a red flag warning.
Fire weather watches and red flag warnings in effect
Fire weather watch vs red flag warning
| Fire weather watch | Red flag warning | |
|---|---|---|
| When | Critical conditions possible in the next 12–72 hours | Critical conditions happening now or expected shortly |
| Certainty | Possible — forecast confidence is still building | Expected or occurring |
| What to do | Plan: check go-bag, fuel the car, clear dry debris, postpone burning | Act: no sparks or flames outdoors, stay alert for fires and alerts |
Both are issued by your local National Weather Service office using thresholds for wind, humidity and fuel dryness that fit that region. A watch is often upgraded to a red flag warning as the event gets closer — or cancelled if the forecast changes.
