Columbia, South Carolina – Severe thunderstorms swept through the Midlands on Wednesday, resulting in widespread power outages and a continuing heat advisory for the region. The WIS viewing area was placed under a Severe Thunderstorm Watch that remains in effect until midnight Thursday, as meteorologists warn of dangerous conditions.
The National Weather Service issued a heat advisory for Columbia for the second consecutive day, with temperatures anticipated to soar above 100 degrees. This follows a high of 97 degrees recorded the previous day. The advisory is effective until 8 p.m., with heat index values potentially soaring as high as 110 degrees.
While no additional alerts are currently in place, storm conditions can change rapidly, and residents are advised to remain vigilant as more thunderstorms are expected. These storms are anticipated to bring significant lightning, which has already posed dangers as evidenced by a recent incident at Lake Murray. On Tuesday, a lightning strike injured 20 individuals, including 12 children. Fortunately, none of the injuries were reported as life-threatening.
The primary concern from Wednesday’s storms includes damaging wind gusts, which may produce isolated winds exceeding 80 mph and widespread gusts surpassing 60 mph. These potent winds pose risks to local trees, mobile homes, and power lines, which could lead to further power outages.
Forecasts predict thunderstorms could begin developing around 2 p.m., with the most intense effects expected between 3 p.m. and 11 p.m.. Specifically, the Columbia area may experience its strongest weather impacts between 5 p.m. and 9 p.m.. Although tornadoes are not expected, residents should be prepared for large hail, which could cause minor vehicle damage in some instances.
As storms pass through, rain accumulation is expected to reach around one inch, with localized higher amounts during intense thunderstorms. While the storms may lower the day’s baking temperatures into the low 70s, triple-digit temperatures earlier in the day remain a high possibility.
The National Weather Service has cautioned that the combination of high temperatures and humidity may contribute to heat-related illnesses such as heatstroke, cramps, and exhaustion. Precautions advised for coping with extreme heat include maintaining hydration, avoiding direct sun exposure, and checking on those especially susceptible to heat, such as the elderly or individuals with certain health conditions.
As a consequence of the storms, reports indicate that nearly 54,000 customers experienced outages at the storm’s peak. The outages primarily affected residents in Richland and Lee counties. Local electric utilities have mobilized resources to assist customers in reporting outages and the damage sustained from the storms.
In conclusion, Columbia, South Carolina, faces a challenging weather day as residents prepare for severe thunderstorms and ongoing high temperatures. Community members are urged to stay alert and take necessary safety precautions against both the extreme heat and potential storm hazards.
