What is the National Weather Service?
The National Weather Service (NWS) is an agency of the National Oceanic and Atmospheric Administration (NOAA), which is a
part of the Department of Commerce. The primary mission of the NWS
involves the protection of life and property as well as enhancement of the national economy. This is
accomplished through weather forecasts and severe weather warnings. However, there is more to the
story and this involves people taking the appropriate action(s) based on such forecasts and
warnings. This part of the equation is the goal of NOAA's "Weather Ready Nation"
campaign to educate and help individuals prepare for severe weather and water events. Learn more
about how you can become "weather ready" here.
What does the Charleston, SC NWS office do?
Our office is responsible for providing forecasts and severe weather warnings for 20 counties across southeast SC and southeast GA, as well as
portions of the Atlantic coastal waters. We routinely
issue public forecasts as well as specialized forecasts/products for the aviation, marine, fire

What is doppler radar?
A doppler radar contains special technology that detects motion toward or away from the radar
antenna, in addition to showing the location of precipitation. The ability to detect motions within
thunderstorms has greatly improved the ability for NWS meteorologists to provide advance notice of
impending severe weather, including tornaodes. Learn more about this technology here.
How does the NWS determine what a "severe thunderstorm"
According to the NWS, a "severe thunderstorm" is one that produces 58 mile per hour
or greater winds and/or 1 inch or greater in diameter hail. Excessive lightning is not considered
during the issuance of Severe
Thunderstorm Warnings, however Special
Weather Statements are often issued to address storms with excessive cloud-to-ground
