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 to 55 minutes, providing critical time for the emergency message to sound NOAA Weather Radio, commercial radio and television, and tornado sirens, the agency says.
For Enterprise, Ala., the preliminary tornado lead time is 18 minutes, NOAA says.
New storm-based warnings, introduced operationally by NOAA's National Weather Service last month, helped to better pinpoint the path ofyesterday's tornadoes resulting in extended lead times and a reduction inthe area warned, as compared to the previous county-based warning method. The tornado warning that included Enterprise, Ala., included a 71% reduction in areas that did not need the warning.
Starting today teams of National Weather Service meteorologists will beon the ground conducting damage surveys in order to determine the exactwind speed, width and path of each twister.
NOAA is not forecasting another severe weather outbreak in the coming days, but encourages residents across the country to purchase a NOAA Weather Radio All Hazards receiver at electronic retailers or online as an essential method of receiving potentially life-saving severe weather warnings.
