Heat Advisory

Dolan Red Flag

N_E Bay, SC RFW

Hot conditions will persist through Friday for all locations away from the immediate coastline. Daytime temperatures will again warm into the low 90s to near 100° with the warmest interior locations reaching up to 105°. Additionally, overnight temperatures will only cool into the 60s in the valleys and 70s to lower 80s in the hills, limiting relief from daytime heating. These conditions will result in an increased risk for heat related illnesses, especially during the afternoon and evening hours. Thus, the Heat Advisory has been extended through Friday evening.
