.Two unique rounds of rainfall, one ongoing and continuing through
early this afternoon resulting from tropical moisture
interacting with a stationary front, and another beginning tonight
and lasting through Friday morning associated with Hurricane
Helene, are expected to result in considerable to catastrophic
Major flooding across the upper Saluda River Valley. This flooding
has the potential to be the worst flooding observed in the modern
era, exceeding even the flooding which occurred on February 6-7,
2020, and rivaling the flooding from 1949.
This flooding may shutdown several roadways. especially above
Piedmont Dam to the Saluda River headwaters above Saluda Lake. A
few roadways may experience strong and damaging streamflows,
possibly causing damage to roadway infrastructure including culverts
and bridges. Several structures, including homes and businesses,
are likely to be inundated as a result of Major flooding. A few
structures may become uninhabitable and some structures may become
completely destroyed due to ruinous flooding.
Confidence in significant rainfall is 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.
