Severe Thunderstorm Warning Issued for Greenville and Spartanburg Counties
Greenville, SC – The National Weather Service (NWS) has issued a Severe Thunderstorm Warning for Greenville and Spartanburg counties, effective until 10 p.m. on Friday night. This warning was released at 9:23 p.m. as strong thunderstorms with the potential for hazardous weather approached the area, bringing high wind gusts and hail.
Doppler radar indicated that a significant thunderstorm was located 4 miles northwest of Columbus, moving east at a speed of 25 mph. Wind gusts associated with the storm are projected to reach speeds of up to 40 mph, while hail could range from marble-sized (approximately 0.5 inches) to an inch in diameter.
Impact and Precautions
Residents in the affected areas, which include Columbus, Flat Rock, Landrum, Tryon, Saluda, Pleasant Ridge State Park, Jones Gap State Park, Caesars Head State Park, Dupont State Forest, and Mill Spring, are advised to take precautions. The potential impacts of these storms include:
- Knocked-down tree limbs
- Unsecured objects being blown around
- Minor damage to outdoor items due to hail
As frequent cloud-to-ground lightning is a characteristic of these storms, the NWS encourages those outdoors to seek shelter in a building. Lightning can strike as far as 10 miles from the storm, posing a significant risk. On average, there are about 25 million lightning strikes across the U.S. annually, which result in approximately 20 fatalities each year.
Weather Conditions and Expectations
Meteorologist reports suggest that significant weather events may persist between 6 p.m. and midnight in Greenville, Spartanburg, and Anderson. An 80% chance of showers and thunderstorms has been predicted, with wind gusts potentially exceeding 58 mph at times. Additionally, a raised threat level from one to two has been issued, indicating the organized nature of these storms.
Factors contributing to the severe weather conditions include an upper disturbance in the atmosphere, leading to a likelihood of isolated thunderstorms continuing into the night. While the chance of precipitation is expected to diminish overnight to 40%, there remains a 70% chance of thunderstorms following the initial warning.
Residents are also reminded to ensure the safety of their pets during this storm period, as they should be brought indoors if outdoors.
Future Weather Outlook
Looking ahead, preconditions on May 9 indicate a 50% chance of precipitation, although a reduced likelihood of hail is forecasted. Conditions are expected to improve over the weekend, with minimal precipitation chances at 30% reported for May 10. However, weather patterns may shift again on May 11, leading to an increase in rain chances up to 40%.
Context of Severe Thunderstorm Alerts
This is not the first severe thunderstorm warning issued for the area. A previous warning was recorded on June 1, highlighting similar threats including wind gusts of up to 60 mph and hail reaching up to 1 inch. During that prior warning, locations affected included Reidville, Five Forks, Lake Robinson, and several others in the region.
The NWS emphasizes the importance of seeking shelter in an interior room on the lowest floor of a building during severe weather. Citizens are encouraged to report damages such as winds, hail, or flooding through designated reporting channels to ensure an accurate assessment of storm impacts.
