WATCHES & WARNINGS
RECOMMENDED LIGHTNING PROCEDURES
- Severe Thunderstorm Watch- Severe thunderstorms are possible in your area. Continue your normal routine, but watch and listen for threatening weather on your local TV or radio weather station.
- Severe Thunderstorm Warning-A severe thunderstorm has actually been reported or sighted on radar moving in your direction. If the thunderstorm appears nearby, take cover. Severe thunderstorms include winds greater than or equal to 58 mph and/or hail.
- Advanced warning of the hazard at the field. Some options:
- "If you can see it, flee it; If you can hear it, clear it."
- check forcast from NOAA Weather Radio
- lightning detectors
- Make decision to suspend activities and notify people.
- The 30/30 Rule says to shut down when lightning is six miles away. Use a "flash to bang" (lightning to thunder) count of five seconds equals one mile (10 = 2 miles; 20 = 4 miles; 30 = 6 miles).
- Notify people via radio, siren or other means.
- Move to safe location.
- A large permanent building or metal vehicle is best.
- Unsafe places are near metal or water; under trees; on hills; near electrical/electronics equipment.
- Reassess the hazard.
- It’s usually safe after no thunder and no lightning have been observed for thirty minutes. Be conservative here.
- Inform people to resume activities.
