Extreme Totals and Flooding
Over that three-day window from Wednesday, September 25 through Friday, September 27, rainfall totals exceeded eight inches across our Mountain region, with a foot or more falling in parts of Alleghany County and in a swath from Boone through Brevard.
More than 18 inches fell across southern Yancey County, western McDowell County, southeastern Buncombe County, and northwestern Rutherford County. That included
24.41 inches at our ECONet station on
Mount Mitchell and
19.99 inches at our station on
Bearwallow Mountain.
The highest apparent total from the event came from the North Carolina Forest Service’s RAWS station in
Busick, with a three-day accumulation of
31.33 inches. While unvalidated at this point,
radar estimates back up the potential for two feet of rain or more in Yancey County.
In addition to these automated weather stations, four CoCoRaHS observers recorded
three-day totals of more than 20 inches: 24.12 inches in
Spruce Pine, 22.36 inches in
Foscoe, 22.12 inches south of
Black Mountain, and 21.96 inches south of
Hendersonville.
