Unfamiliar With Weather And Local Factors

 

Watch Out Situation #4:  Unfamiliar with weather and local factors influencing fire behavior.

4. Unfamiliar with weather and local factors influencing fire behavior. Three firefighters examine weather instruments while standing in a wide open, grassy area. Large white clouds appear to grow in the distant sky.


Read about all 18 Watch Out Situations.

What kinds of questions would you ask of local experts?

Does the operational period plan or Incident Action Plan (IAP) give you adequate weather information? What kinds of weather forecasts are available? What other weather or local information do you look for in the plan?

Can you get information from resources that have been on the fire? What questions will you ask of the crew that you are replacing?

Is there any other way to obtain information? List common sources of information on weather and local factors. Examples include web-based Weather Activity Planner, Point Forecast Matrix, National Oceanic and Atmospheric Administration (NOAA) Internet Briefing.

3. Base all actions on current and expected behavior of the fire. A firefighter looks at his watch, which reads 2 PM, while a fire actively grows in steep terrain and heavy timber.
4. Identify escape routes and safety zones, and make them known. A fire crew is walking through a meadow on a path lined with pink flagging. Behind them, a fire is growing in heavy timber.
5. Post lookouts when there is possible danger. A firefighter works by a water pump in a creek. Two firefighters spray water onto flames. And another firefighter talks into a radio while observing all firefighters.

To Reduce Risks:

  • Standard Firefighting Order #3: Base all actions on current and expected fire behavior.
  • Standard Firefighting Order #4: Establish escape routes and safety zones.
  • Standard Firefighting Order #5: Post lookouts.
  • Discuss a fire where you relied on information from the local unit. For example, where your fire knowledge and experience were very different from how they did things—such as in the southeastern United States or Alaska.
  • Recognize and report visual indicators (clouds, weather observed, cold front passage, inversion breaking).

Questions?  Please contact:
Equipment Technology Committee

The U.S. Forest Service National Technology and Development Program (NTDP) is seeking input on the Forest Service-designed flame-resistant (FR) shirt, currently available through the National Interagency Support Cache system and FedMall.

NTDP is conducting a product review to improve future FR shirt designs. As part of this effort, a short survey is now open for federal employees who have worn any of three recent FR shirt models. Feedback will guide design improvements to better meet the needs of wildland firefighters.

To comply with the Paperwork Reduction Act, responses are limited to federal employees. The survey is open through September 12, 2025.

EMC Memo 25-001: Interim Rapid Extraction Module (REMS) Training and Qualification Requirements

Date: June 3, 2025
Questions?  Please contact:
Emergency Medical Committee

The Emergency Medical Committee has issued interim guidance for Rapid Extraction Module Support (REMS) teams. Until further notice, Type I and II REMS teams must designate a team leader qualified at Firefighter Type 1 Squad Boss (FFT1) or higher. This temporary change replaces the Single Resource Boss (SRB) requirement, which is currently not feasible due to administrative barriers.

This memorandum does not include any other changes to the NWCG Standards for Rapid Extraction Module Support, PMS 552. This interim change takes effect immediately and will remain in place until further notice.
