CHARLESTON, S.C. (WCSC) - Portions of the Lowcountry will find themselves under a heat advisory Thursday morning.
With heat index values up to 112°F, the National Weather Service issued a heat advisory for Charleston and Beaufort counties plus coastal Colleton and tidal Berkeley counties.
The advisory runs from 11 a.m. - 6 p.m.
The Live 5 Weather team declared First Alert Weather Days through Friday as the heat index was expected to remain in three digits.
Heat will still be a factor in areas not under the heat advisory as heat index values could still exceed 100°F, Live 5 Meteorologist Joey Sovine said.
Heat is one of the leading weather-related killers in the United States, resulting in hundreds of deaths and fatalities each year, the National Weather Service reports.
Young children and infants are particularly vulnerable to heat-related illness and death because their bodies are less able to adapt to heat. Older adults, particularly those with pre-existing medical diseases or who take certain medications, or who have limited mobility or may live alone can also be susceptible.
It is never safe to leave a child, disabled person or pet locked in a car, even in the winter. If you have a toddler in your household, lock your cars, even in your own driveway. Kids play in cars or wander outside and get into a car and can die in 10 minutes. A reported 33 children died in hot cars in 2022.
