Safety Precautions & Preparedness Guidelines

Roadway Safety

• Early Morning Frost & Sun Glare: Ensure windshields and mirrors are completely clear of frost before driving prior to 9:00 a.m. today, and watch for slick spots on shaded bridges and Intracoastal Waterway overpasses. Low autumn sun angles under clear skies will also create strong glare during morning and late-afternoon commutes all week.

• Breezy Monday Night Travel: High-profile vehicles crossing coastal bridges and open stretches of Highway 17 and Highway 31 should use caution Monday night as northeast gusts reach up to 16 mph.

Ocean, Beach & Plant Safety

• Cold Water & Breezy Surf: Cool north-to-northeast winds and brisk water temperatures require layered clothing and proper flotation gear for boaters, anglers, and beachgoers.

• Sensitive Vegetation: Keep tender outdoor plants covered until temperatures rise above the mid-30s after 9:00 a.m. this morning.
