EIP-ZZ-00231 Rev. 012 RESPONSE TO SEVERE THUNDERSTORM/HIGH WINDS/TORNADO WATCHES AND WARNINGS 1 PURPOSE AND SCOPE 1.1 PURPOSE This procedure establishes the method for responding to severe thunderstorm watches, thunderstorm warnings, high winds, tornado watches, or tornado warnings.
1.2 SCOPE
1.2.1 Establishes
- a. The means of notifying plant workers of severe weather.
- b. The response of plant workers to severe weather.
- c. Emergency actions necessary to be taken in the case of severe weather.
- d. The procedures necessary to control the opening and closing of specified missile shields.
- e. Requirements associated with placing a Sea-land container on the roof the Diesel Generator Building(s).
2 DEFINITIONS 2.1 APPROACHING (severe levels) - A thunderstorm which contains winds of 40 to 57 mph, or hail 1/2 inch or larger but less than 3/4 inch in diameter.
2.2 FUNNEL CLOUD - A condensation funnel extending from the base of a towering Cumulus or Cumulonimbus cloud (Cb), associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado).
2.3 HIGH WINDS - Winds in excess of 40 mph (18 m/s) sustained, or 58 mph (26 m/s) gusting.
EIP-ZZ-00231 Rev. 012 2.4 National Oceanic and Atmospheric Administration (NOAA) - An organization of the U.S. Commerce Department. NOAA's National Weather Service keeps a round-the-clock vigil on atmospheric conditions and issues watches and warnings for severe atmospheric conditions. A weather radio which can receive NOAA weather announcements is located in the Control Room, in the Shift Supervisor's office, and is activated when local severe weather conditions exist.
2.5 SEVERE THUNDERSTORM - A thunderstorm which produces tornadoes, hail 0.75 inches or more in diameter, or winds of 58 mph or more. Structural wind damage may imply the occurrence of a severe thunderstorm. See approaching (severe).
2.6 THUNDERSTORM - Rain clouds producing lightning.
2.7 TORNADO WATCH - Identifies an area where conditions are favorable for a tornado formation.
2.8 TORNADO WARNING - A tornado warning means that a tornado has been sighted or indicated by weather radar.
2.9 TORNADO - A violently rotating column of air in contact with the ground and extending from the base of a thunderstorm. A condensation funnel does not need to reach to the ground for a tornado to be present; a debris cloud beneath a thunderstorm is all that is needed to confirm the presence of a tornado, even in the total absence of a condensation funnel.
2.10 WARNING - Issued by NWS local offices indicating that a particular weather hazard is either imminent or has been reported. A warning indicates the need to take action to protect life and property.
The type of hazard is reflected in the type of warning (e.g., tornado warning, blizzard warning).
2.11 WATCH - A National Weather Service (NWS) product indicating that a particular hazard is possible, i.e., that conditions are more favorable than usual for its occurrence. A watch is a recommendation for planning, preparation, and increased awareness (i.e., to be alert for changing weather, listen for further information, and think about what to do if the danger materializes).
EIP-ZZ-00231 Rev. 012 3 RESPONSIBILITIES 3.1 SHIFT SUPERVISOR 3.1.1 Ensures Attachment 1, Announcements for High Winds/Tornado's, is completed during severe thunderstorm watches, high winds, tornado watches, or tornado warnings.
