Weather Forecast Office
These instructions are only intended for reporting significant weather across northeast South Carolina and southeast North Carolina in the counties shown on the map below. To be sure that you're reporting to the right place, click on this link and enter your location to find your local NWS office. Our neighboring offices include: Charleston, SC | Columbia, SC | Raleigh, NC | Newport/Morehead City, NC
Despite having many types of observations at our disposal, we cannot see exactly what's happening everywhere at all times. Thus, you can help be our "eyes and ears" in the field to assist us with forecast verification, and more importantly, warnings for hazardous weather. Although we'd like to hear of any significant weather phenomena that you observe, we're particularly interested in reports of severe weather such as tornadoes/waterspouts, 1" (quarter size) or larger hail, damaging winds and/or flash flooding. Refer to the tabs below for more details regarding these hazards as well as other phenomena.
See below for the various ways of contacting us. Feel free to let us know if you are a trained SKYWARN storm spotter and/or your affiliation (e.g., ham radio operator, law enforcement). After quality controlling your report, we may use it to issue a Local Storm Report (LSR).
See below for the information you should include in your reports. You can use the "T-E-L" (T=Time / E=Event / L=Location) method for reporting.
Tornado: A violently rotating column of air extending from the base of a thunderstorm cloud to the ground. If a tornado is over water it is classified as a waterspout. The Enhanced Fujita (EF) Tornado Intensity Scale (seen below) is used to categorize the strength of tornadoes. We assign these ratings after we go out and survey the damage. More information about the EF scale and damage indicators are located here.
Enhanced Fujita (EF) Tornado Intensity Scale
EF Rating | 3 Second Gust (mph) |
---|---|
0 | 65-85 |
1 | 86-110 |
2 | 111-135 |
3 | 136-165 |
4 | 166-200 |
5 | Over 200 |
Funnel Cloud: A condensation funnel extending from the base of a towering cumulus or cumulonimbus cloud, associated with a rotating column of air that is not in contact with the ground/water surface. Not all funnel clouds will become tornadoes. A condensation funnel only becomes a tornado if either a) it becomes in contact with the ground/water surface or b) a debris cloud or dust whirl is visible beneath it.
