The frost and freeze will end the growing season across the region, potentially damaging sensitive plants. Residents are advised to protect plants, bring pets indoors, and ensure livestock are warm. Gusty winds in the mountains could create hazardous wind chills and slick road conditions due to light snow accumulation. The coldest temperatures are expected Saturday night, with lows in the low 30s °F (around 0 °C) in the Upstate and mid-20s °F (-4 to -3 °C) in mountain valleys. These conditions may pose risks to those without adequate heating or shelter.
