South Carolina Heat Emergency: Temperatures Soar to 107°F, Heat Advisories in Effect Through Monday Night
COLUMBIA, SC — A blistering heat wave has settled over South Carolina, pushing heat index values up to 112°F across the Midlands and prompting multiple heat advisories and warnings from the National Weather Service.
The advisory covers a large swath of counties including Lexington, Sumter, Orangeburg, Saluda, and Richland, with alerts in place through 9 p.m. Sunday, and an Extreme Heat Watch continuing through Monday evening at 8 p.m.
Dangerous Heat Index Nears Record Levels
The NWS Columbia office reports that actual high temperatures are expected to hit 103°F on both Sunday and Monday, with humidity making it feel significantly hotter — as high as 112°F. Overnight lows will only fall to the low 80s, offering minimal relief for vulnerable populations.
The advisory warns of increased risk for heat-related illnesses, especially among:
- Children
- Outdoor workers
- The elderly
- People without access to air conditioning
Officials are urging residents to stay indoors during peak hours, stay hydrated, and check on neighbors, especially the elderly or those without cooling systems.
Impact on Travel and Infrastructure
Travelers across I-20, I-26, and I-77 should expect potential road delays or emergency closures, as road crews may adjust work schedules to avoid peak heat conditions.
Utility companies have begun preparing for surges in electricity use, which could strain parts of the power grid. Blackouts are not expected but remain possible if usage exceeds forecasted levels.
