| Brief Description | Flood Warning | |
| Detailed Description | The National Weather Service in Greenville-Spartanburg SC has issued a Flood Warning for the following rivers in North Carolina. French Broad River Near Fletcher affecting Buncombe and Henderson Counties. French Broad River At Blantyre affecting Henderson and Transylvania Counties. French Broad River At Asheville affecting Buncombe County. French Broad River At Marshall affecting Madison County. French Broad River Near Hot Springs affecting Madison County. Swannanoa River At Biltmore affecting Buncombe County. .Two unique rounds of rainfall, one beginning tonight and lasting through early Thursday afternoon resulting from tropical moisture interacting with a stationary front, and another beginning Thursday night and lasting through Friday morning associated with Hurricane Helene, are expected to result in considerable to catastrophic Moderate to Major flooding across much of the French Broad River and Swannanoa River valleys. This flooding has the potential to rival the Major, catastrophic flooding observed in September 2004 from Hurricanes Frances and Ivan, especially from the French Broad River headwaters near Rosman and Blantyre to Asheville. This flooding will shutdown numerous roadways. Several roadways will experience strong and damaging streamflows, likely causing damage to roadway infrastructure including culverts and bridges. Primary roadways that do not typically flood will likely flood, resulting in very significant impacts to travel. Travel may become very difficult and dangerous. Numerous structures, including homes and businesses, are likely to be inundated as a result of Major flooding. Many structures may become uninhabitable and some structures may become completely destroyed due to ruinous flooding. There is a potential for crests to exceed the current forecast crests. Confidence in significant rainfall is very high, but small reductions or increases in storm-total rainfall may result in notable changes to the forecast crests. It is absolutely imperative that you maintain awareness of the latest forecasts and plan NOW to respond to the worst-case scenario for your area. * WHAT. Major flooding is forecast. * WHERE.
