# Talk Fire Weather

Part of the Wildland Fire Management Merit Badge Digital Resource Guide: [Introduction & Overview](https://merit-badge.university/merit-badges/wildland-fire-management/guide/index.md)

*9. Taking Action*

> **9e.** Meet with a meteorologist or someone familiar with fire weather and discuss the fire weather concerns and typical fire seasons that exist in your area. Discuss the conditions that lead to a Fire Weather Watch or a Red Flag Warning. Discuss what you learned with your counselor.

Fire weather forecasters occupy a strange position: they issue a product, and thousands of people change what they do because of it. Burn permits get suspended. Utilities cut power to whole neighborhoods. Fire agencies staff extra engines and stage them at high-risk locations. Land managers cancel prescribed burns they have waited two years to conduct. All of that turns on a forecast of humidity and wind.

This option puts you in a room with the person who makes that call.

## Finding a Fire Weather Expert

- **Your local National Weather Service (NWS) forecast office.** Every office has fire weather responsibility for its area and a designated fire weather program leader. NWS offices do public outreach regularly and are used to hosting visitors and doing virtual talks.
- **An Incident Meteorologist (IMET).** These are NWS forecasters specially trained to deploy to large wildfires and forecast from a trailer at incident base. There are relatively few nationally, so if one is available to you, take the meeting.
- **State forestry or federal agency fire weather staff**, including fire behavior analysts and predictive services meteorologists at Geographic Area Coordination Centers.
- **A broadcast meteorologist** at a local TV station, especially in fire-prone regions where they cover red flag days routinely.
- **A university atmospheric science department**, if there is one near you.

> Arrange this meeting through your parent or guardian and let your counselor know the plan. Scouting America's Youth Protection policies require two-deep leadership and prohibit one-on-one contact with adults outside Scouting, so bring an adult with you — including for a video call.

## Fire Weather Concerns in Your Area

Go in already knowing the vocabulary from [Req 5a](https://merit-badge.university/merit-badges/wildland-fire-management/guide/req5/) so you can ask real questions instead of definitions.

Topics worth covering:

- **Which weather element drives fire behavior most where you live** — wind, humidity, drought, or lightning. The answer differs sharply by region.
- **Named local wind events.** Many regions have them, and they are usually the reason the worst fires happen: Santa Ana and Diablo winds in California, Chinook winds along the Front Range, foehn and downslope wind events in many mountain areas, and gap winds through terrain constrictions. Ask what yours is called and what sets it up.
- **Dry thunderstorms and lightning outbreaks,** and how the office forecasts them.
- **Drought indices** such as the Keetch-Byram Drought Index or Energy Release Component, and how the office uses them.
- **Inversions and mixing height** — why a fire behaves calmly in the morning and explodes when the inversion breaks, and where smoke will go.
- **Humidity recovery overnight**, which determines whether crews get a working window at dawn.
- **How forecasts get to firefighters,** including spot forecasts requested for a specific fire and how an IMET operates on an incident.

## Typical Fire Seasons in Your Area

Ask when your area burns and — more interestingly — *why then*. Fire season is set by when vegetation cures, when precipitation stops, when winds arrive, and when people are out on the landscape. Many regions have two distinct seasons: a spring season before green-up and a late-summer or autumn season after fuels dry out. Ask whether your season has been shifting or lengthening, what the forecaster watches to know it has begun, and what a bad season looks like compared to a normal one.

## Fire Weather Watch vs. Red Flag Warning

This is the specific pair the requirement names, so make sure you can explain both precisely.

Both products are issued by the National Weather Service in coordination with land management agencies, and both require **two ingredients together**: critical **fuel** conditions, determined by the land management agencies, plus critical **weather** conditions, determined by the NWS forecaster. Dry, windy weather over green, wet fuels does not produce either product.

| | Fire Weather Watch | Red Flag Warning |
| --- | --- | --- |
| **Meaning** | Critical fire weather conditions are **possible** | Critical fire weather conditions are **occurring or imminent** |
| **Timing** | Typically issued 24 to 72 hours ahead | Issued when conditions are ongoing or expected generally within 24 hours |
| **Confidence** | Conditions could develop | Forecaster has high confidence, or it is already happening |
| **Message** | Be prepared — plan ahead | Take action now |
| **Typical response** | Agencies review staffing, plan resource pre-positioning, review burn plans | Burn permits suspended, extra engines staffed and pre-positioned, prescribed burns cancelled, utilities may shut off power |

Two details are worth carrying into your counselor discussion:

- **A Red Flag Warning does not have to be preceded by a Watch.** If the situation develops quickly, the office can go straight to a warning.
- **The specific thresholds vary by state and by NWS office.** Criteria are set in annual operating plans coordinated between the NWS and land management agencies in each state, so the humidity and wind numbers that trigger a warning in Colorado are not the ones used in Georgia. A typical western threshold pairs relative humidity at or below roughly 15 percent with sustained winds or frequent gusts around 25 mph, but you should ask for *your* office's actual criteria — and getting those specific numbers is one of the best things you can bring back from this meeting.

Other triggers your forecaster may mention include the first significant lightning after a hot dry period (which can justify a warning regardless of humidity) and a dry cold frontal passage bringing an abrupt wind shift with little or no rain.

**Questions That Get the Best Answers** — Ask these and you will leave with real material

- [ ] **What are this office's actual Red Flag criteria?** Numbers, not generalities.
- [ ] **What is the most challenging fire weather situation you forecast here, and why?**
- [ ] **Have you ever been wrong in a way that mattered?** Forecasters are usually candid about this, and the answer is memorable.
- [ ] **How do you decide between a Watch and going straight to a Warning?**
- [ ] **What is a spot forecast, and how does an incident request one?**
- [ ] **What should my troop check before a campout in fire season?** Ask for the exact product or webpage they would use.
- [ ] **What does an IMET do on a fire?** Even a forecaster who has never deployed can describe it.

> **Tip**
>
> Prepare by tracking fire weather for a week before the meeting. Pull up your NWS office's fire weather page daily, note the relative humidity, wind, and any watches or warnings, and write down what you observe outside. Walking in able to say "you had a Red Flag Warning last Tuesday — what tipped it?" transforms the conversation from an interview into a discussion between people who both watched the same weather.

## Following Up With Your Counselor

Write your notes up the same day, organized around the three required topics: local fire weather concerns, typical fire seasons, and the Watch/Warning distinction with your area's actual criteria. Then discuss it with your counselor, and connect it back to the fire environment triangle from [Req 5a](https://merit-badge.university/merit-badges/wildland-fire-management/guide/req5/) — weather is the leg that changes hour to hour, and this option is where you learn who watches it.

Whichever option you chose, Requirement 9 was about your own area right now. The next requirement goes the other direction: back into history, to a fire that changed the profession.
