The primary risk is posed by the dangerous rip currents along South Carolina beaches, which can sweep swimmers into deeper waters, creating life-threatening situations. This is particularly concerning for beachgoers in Beaufort, Coastal Colleton, Charleston, and Coastal Jasper. Swimmers, especially those who are inexperienced, are advised to exercise extreme caution and avoid entering the water during this period. Additionally, gusty winds of up to 30 mph tonight may create minor hazards for outdoor activities.
