Thunderstorm Safety

Thunderstorms cause significant hazards for wildland firefighters, including downbursts. Downbursts can cause extreme fire behavior and lightning. When thunderstorm development is likely, lookouts should be aware of the signs.

Approaching thunderstorms may be noted by a sudden reverse in wind direction, a noticeable rise in wind speed, and a sharp drop in temperature. Rain, hail, and lightning occur only in the mature stage of a thunderstorm.

Situation Awareness: Sound waves move at different rates based on atmospheric conditions. Take the storm precautions below as soon as you hear thunder, not when the storm is upon you. Do not resume work in exposed areas until 30 minutes after storm activity has passed.

Hazard Control:

  • Take shelter in a vehicle or building if possible.
  • If outdoors, find a low spot away from tall trees, wire fences, utility lines and other elevated conductive objects. Make sure the place you pick is not subject to flooding.
  • If in the woods, move to an area with shorter trees.
  • If only isolated trees are nearby, keep your distance twice the tree height.
  • If in open country, crouch low, with feet together, minimizing contact with the ground. You can use a pack to sit on, but never lie on the ground.
  • If you feel your skin tingle or your hair stand on end, immediately crouch low to the ground. Make yourself the smallest possible target and minimize your contact with the ground.
  • Don’t group together.
  • Don’t stay on ridge tops, in wide open areas, or near ledges or rock outcroppings.
  • Don’t operate landline telephones, machinery, or electric motors.
  • Don’t handle metal hand tools or flammable materials in open containers.

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.
