Event:
Flood Warning
Urgency:
Immediate
Effective:
September 26, 2024 - 6:48pm
Expires:
September 27, 2024 - 7:00am
Description:
...The Flood Warning continues for the following rivers in North
Carolina...
French Broad River At Marshall affecting Madison County.
French Broad River Near Hot Springs affecting Madison County.
French Broad River At Blantyre affecting Transylvania and
Henderson Counties.
French Broad River At Asheville affecting Buncombe County.
French Broad River Near Fletcher affecting Henderson and Buncombe
Counties.
Swannanoa River At Biltmore affecting Buncombe County.
.Ongoing rain associated with Helene will continue overnight tonight
into Friday morning. Considerable to catastrophic Moderate to Major
flooding across much of the French Broad River and Swannanoa River
valleys is expected as a result of this extremely rare high
rainfall. 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.
