NOAA PROVIDES CRITICAL LEAD TIME FOR SOUTHEAST TORNADOES
2, 2007 — Tornadoes that tore across the Southeast on Thursday struck
after significant advance warning from the NOAA National Weather Service.
Preliminary Tornado Warning lead times—the amount of time between
the issuance of a Tornado Warning and the touchdown of a tornado—ranged
from 12 minutes to 55 minutes, providing critical time for the emergency
message to sound NOAA Weather
Radio, commercial radio and television and tornado sirens. For Enterprise,
Ala., the preliminary tornado lead time was 18 minutes. (Click

county-based warnings. Please credit “NOAA.”)
Friday, teams of NOAA National Weather Service meteorologists will be
on the ground conducting damage surveys in order to determine the Enhanced
Fujita Scale rating, wind speed range, approximate times, width and
path of each twister.
NOAA, an agency of the U.S. Commerce Department, is celebrating 200 years of science and service to the nation. From the establishment of the Survey of the Coast in 1807 by Thomas Jefferson to the formation of the Weather Bureau and the Commission of Fish and Fisheries in the 1870s, much of America's scientific heritage is rooted in NOAA. NOAA is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and information service delivery for transportation, and by providing environmental stewardship of the nation's coastal and marine resources. Through the emerging Global Earth Observation System of Systems (GEOSS), NOAA is working with its federal partners, more than 60 countries and the European Commission to develop a global monitoring network that is as integrated as the planet it observes, predicts and protects.
