Frost Advisory in Effect Until 9 AM Sunday for Western North Carolina Mountains Including Asheville, Waynesville and Surrounding Counties
ASHEVILLE, NC — A Frost Advisory is in effect until 9:00 AM EDT Sunday, May 3, 2026 across a broad swath of the western North Carolina mountains. Temperatures dropping to near 33 degrees Fahrenheit overnight are expected to produce frost conditions capable of damaging sensitive plants and vegetation across the region.
Who Is Under the Advisory
The advisory covers multiple counties across the southern Appalachian mountain zone including Rabun, Madison, Yancey, Mitchell, Swain, Haywood, and at least 13 additional counties. Key communities inside the advisory zone include Asheville, Waynesville, Bryson City, Franklin, Robbinsville, Hendersonville, Sevierville, Maryville, and Pigeon Forge along the Tennessee border.
What Frost at 33 Degrees Does to Plants
At temperatures near 33 degrees, ice crystals form on exposed plant surfaces and inside plant tissue. This process ruptures cell walls in sensitive plants, causing visible wilting, blackening, and in some cases killing the plant entirely. Tender annuals, newly planted vegetables, tropical plants, and spring blooms are most vulnerable.
What to Do Before Tonight
Cover sensitive outdoor plants with cloth, burlap, or frost blankets before sunset. Do not use plastic directly on plants as it can trap moisture and cause additional damage. Potted plants should be brought indoors entirely. Plants in low-lying areas and valley floors are at higher risk as cold air drains downhill and pools overnight.
