CHARLESTON, SC (WCSC) - The National Weather Service issued a heat advisory for eastern South Carolina until 7 p.m., when the Lowcountry could also experience powerful storms.
With heat index values expected to reach as high as 110 degrees, the weather service is alerting residents in Charleston, Berkeley, Dorchester, Colleton, Williamsburg, and Georgetown Counties. The advisory also covers Allendale, Florence, Hampton, Horry, Jasper and Marion Counties.
Meteorologist Justin Lock says a cold front that's unusually strong for midsummer could bring the threat of powerful storms through the area in the late afternoon hours, between 4 p.m. and 8 p.m. Residents along the path of the front could see damaging wind gusts of up to 60 mph and large hail, Lock said.
"The good news is this front will bring slightly cooler and less humid air for the next couple of days," Lock said.
But until that happens, forecasters say temperatures are expected to reach the upper 90s with dew points in the low to mid 70s, creating a combination of heat and humidity that could lead to heat illnesses if proper precautions are not taken. Those precautions include drinking plenty of fluids if you must be outdoors, as well as wearing light-weight clothing. Experts advise people to stay out of direct sunlight during a heat advisory and, if possible, to reschedule strenuous outdoor activities to the early morning or evening hours.
Young children and the elderly are most susceptible to heat-related illnesses. Children and pets should never be left in a vehicle since temperatures can increase rapidly inside a closed vehicle.
