Severe storms expected in Western NC, tornado possible: See the latest forecast

Severe weather is expected in Western North Carolina beginning tonight, Saturday, March 15.

National Weather Service forecasts call for showers and thunderstorms as well as gusty winds Saturday night through Sunday night. A wind advisory and hazardous weather outlook have been issued, warning residents of the area of possible danger brought by the storm front.

Here’s what we know about the hazards beginning Saturday night.

Heavy wind warning

A wind advisory issued by the NWS at 1:56 p.m. on Saturday, March 15, is affecting Buncombe, Graham, Haywood, Macon, Madison, Northern Jackson, Southern Jackson and Swain Counties. The advisory, in affect from 6 p.m. Saturday until 2 p.m. Sunday, warns of south winds reaching 20-30 mph with gusts of 40-50 mph expected in the valleys. Winds will gust as high as 70 mph on high peaks and ridgetops.

Winds of this force may blow around unsecured objects and blow down tree limbs, potentially resulting in some power outages. Extra precaution is also advised for drivers, as driving may be more difficult, especially for high profile vehicles.

Thunderstorms, possible flooding, tornadoes

A hazardous weather outlook issued by the NWS at 2:53 p.m. on Saturday, March 15, is affecting northeast Georgia, WNC and Upstate South Carolina. Also in affect 6 p.m. Saturday to 2 p.m. Sunday, the outlook warns of a powerful storm system that will bring heavy rain and severe storms.

Main hazards mentioned in the outlook included damaging wind gusts, as well as “a strong tornado or two” possible in the affected region during the storm. In a Friday report from the Citizen Times, NWS Meteorologist Chris Horne said that while no widespread or severe flooding is expected, some areas of WNC could see heavy or excessive rainfall that could lead to isolated flooding. This was reiterated in the outlook, with highest possibility for flooding in the S.C., Georgia and southwest N.C. mountains.

Strong to severe storms may redevelop Sunday afternoon, but NWS confidence is currently low.
