Localized flash flooding, especially in urban areas, can impede traffic and damage infrastructure, while gusty winds increase the risk of power outages and falling debris.
This weather event is part of a broader pattern of severe weather moving through the Southeast. While the threat is concentrated in southern South Carolina, the impact of heavy rain and wind affects all major urban centers in the region, requiring residents to remain weather-aware through Saturday evening.
