Residents of Union County, South Carolina, are on alert as strong thunderstorms are expected to roll through the area, according to the National Weather Service (NWS). The NWS issued a weather alert on Sunday, March 16, 2025, at 8:33 AM, predicting severe weather conditions including gusty winds.
The thunderstorm warning is set to last until 9:45 AM, with forecasts indicating wind gusts could reach up to 50 miles per hour. This weather event is characterized by powerful storms tracked by Doppler radar along a line extending from six miles south of Indian Land to seven miles east of Springdale, with the overall movement directed northeast at approximately 45 mph.
Key locations within the alert area include Marshville, Indian Trail, Trinity, Lake Park, Wesley Chapel, Monroe, Jaars, Marvin, Wingate, and Stallings, all of which could experience the brunt of these storms. Residents are advised to monitor local radio and television broadcasts for continued updates.
“If outdoors, seek shelter inside a building,” the NWS suggests, emphasizing the potential for storms to intensify. Gusty winds could not only damage property but may also result in downed tree limbs and scattered debris, potentially leading to localized power outages. It is best to remain indoors until the threat has passed to mitigate the chance of injury.
Lightning poses another significant risk with thunderstorms. The NWS notes nearly 25 million lightning strikes occur annually across the United States, predominantly during the summer months. These strikes lead to roughly 20 fatalities each year. To protect against lightning strikes, individuals should prepare to find shelter at the first sign of ominous weather.
During thunderstorms, it is advised to stay indoors and avoid contact with corded telephones, electrical appliances, plumbing, and even windows and doors. According to the NWS, you should wait at least 30 minutes after the last hearing of thunder or seeing lightning before stepping back outside.
For those caught without immediate access to shelter, NWS outlines several safety strategies: avoid open fields and high ground, stay away from tall trees, and if camping, find lower ground. Wolves and wet gear should be avoided, as they can act as conductors for potential strikes. While it is best to seek solid indoor shelter, keeping distance from water and metallic objects is also advised.
Later on the same day, at 7:48 PM, the NWS also issued updated wind advisories valid for various areas including Greater Oconee, Greater Pickens, Southern Spartanburg, and Greenwood County. The advisory, which lasts from midnight through 2 PM on March 16, forecasts south winds at speeds of 15 to 25 mph with gusts of up to 50 mph.
The advisory details highlight risks such as difficulties in driving for high-profile vehicles and the potential for damage to unsecured items outdoors. “Winds this strong can blow around unsecured objects and could knock down tree limbs,” the NWS reported. “A few power outages may result.”
While the situation appears serious, there are proactive measures residents can take to safeguard themselves as these storms develop. When driving during inclement weather, motorists are urged to turn on their headlights, which helps improve visibility even during daylight. It is safer to drive in the middle lanes of the roadway as rainwater typically collects along the edges, and avoiding puddles is key to preventing hydroplaning.
Hydroplaning occurs when water accumulation on roadways is more than the tires can disperse, causing the vehicle to lose traction and control. The NWS warns this can frequently happen at increased speeds or with worn tires. If drivers experience hydroplaning, they should ease off the accelerator, steer gently to regain control, and avoid hard braking, especially for vehicles lacking anti-lock brakes.
The combination of thunderstorms and high winds highlights the necessity for residents to stay alert and be prepared for rapid changes. The potential for severe weather can affect daily life, making it imperative to have safety protocols and contingency plans ready at all times. Following the advise of the NWS and staying informed via reliable weather sources can help mitigate some risks from these unpredictable storms.
This weather advisory and warnings are part of broader, contingent plans ensuring residents remain safe during potentially hazardous weather conditions. Observing these precautions could mean the difference between safety and danger during storms.
