Greenville-Spartanburg Forecast Program Notes
Zone Forecasts
The NWS office in Greenville-Spartanburg issues a 7 day forecast for
each of 46 counties in our county warning
and forecast area (abbreviated CWA or, sometimes, CWFA), which
includes upstate South Carolina, western North Carolina and extreme
northeast Georgia. This product is entitled "Zone Forecast Product"
and issued four times daily at approximately 4 am, 10:30 am, 3:30
pm, and 10:00 pm, but more frequently during active or changeable
weather. Here is a map that displays the zone
codes assigned to counties across our forecast area.
Long fused watches, warnings and advisories
The NWS office in Greenville-Spartanburg issues Watches for Floods,
Flash Floods and Winter Storms. We issue Warnings for Freezes &
Frosts (during the growing season), High Wind, Wind Chill and Excessive
Heat. We also issue advisories for Dense Fog, Winter Weather, High
Wind, Wind Chill and Excessive Heat.
Short fused weather warnings
The NWS office in Greenville-Spartanburg issues short fused warnings
for tornadoes, severe thunderstorms, flooding and flash flooding for
our CWA in Upstate South Carolina, western North Carolina, and northeast
Georgia.
Short Term Forecasts
The NWS office in Greenville-Spartanburg issues a Short Term Forecast
for all 46 counties in the county warning area. This is an "event-driven"
product, meaning that it is not issued during benign or fair weather
conditions. The Short Term Forecasts, or NOWCASTs are issued frequently
in adverse weather conditions and can be issued as often as every
hour in severe weather.
Area Forecast Discussion
The NWS office in Greenville-Spartanburg issues an Area Forecast Discussion
(AFD) several times a day. The primary function of the AFD is to explain the technical
and scientific basis for forecast decisions and accounts for coordination
among adjacent field offices and national centers. This product also
informs other government agencies, private sector meteorologists,
the media and the public about the short and medium range forecast
concerns. |
