Residents and visitors are urged to take precautions as dangerous heat is expected across the South Carolina Lowcountry and southeast Georgia through the end of the week and into the weekend.
According to the National Weather Service (NWS) Charleston, a Heat Advisory is in effect today from 11 a.m. until 8 p.m. for coastal portions of southeast South Carolina and southeast Georgia, with heat index values reaching up to 110°F. An Extreme Heat Watch is in effect Thursday for coastal counties, where heat index values could reach 115°F. Additional heat advisories will likely be needed across the region through the week and into the weekend.
Thursday & Friday: Dangerous Heat Continues
Thursday and Friday are expected to bring some of the hottest conditions with afternoon temperatures forecasted to reach the upper 90s, with some locations potentially approaching 100°F. Heat index values could reach 105–108°F west of I-95 and as high as 115°F closer to the coast.
The NWS also reports that record high temperatures and record-high minimum temperatures could be challenged during this period. Very warm overnight temperatures will provide little relief from the heat, increasing the risk of heat-related illness, particularly for those without adequate air conditioning.
Heat Safety Tips
Everyone should take this heat seriously and take steps to protect themselves, their families and their neighbors.
- Stay hydrated. Drink plenty of water throughout the day and don't wait until you're thirsty.
- Stay cool. Spend as much time as possible in air-conditioned locations and avoid prolonged exposure to direct sunlight.
- Limit strenuous outdoor activity. If you must work or exercise outside, try to do so during the cooler morning or evening hours and take frequent breaks in shaded or air-conditioned areas.
- Check on others. Pay special attention to older adults, young children, neighbors and anyone who may not have reliable access to air conditioning.
- Never leave children or pets in a vehicle. Vehicle interiors can become dangerously hot within minutes.
- Know the signs of heat illness. Heavy sweating, weakness, dizziness, headache, nausea and muscle cramps can be signs of heat exhaustion.
- Act immediately for heat stroke. Confusion, loss of consciousness or other severe symptoms can indicate heat stroke. Heat stroke is a medical emergency, call 911 immediately.
