* ADDITIONAL DETAILS...
- At 724 PM EDT, Rainfall accumulations of 4-8 inches Wednesday
night into Thursday morning over the headwaters of the
Catawba River and associated tributaries has caused high
inflows into Lake Rhodhiss. Lake Rhodhiss is rising steadily
in response to this rainfall but the current pool of 95.53
feet is well below the full pool of 100.0 feet. Additional
rises are expected, however, through the overnight hours,
with Lake Rhodhiss likely to approach the Action/Advisory
Stage of 102.0 feet. At this level, nuisance shoreline
flooding and flooding of lake access areas, campgrounds,
docks, swimming areas, and residential yards is expected.
Caution is advised anywhere near such areas.
Additional torrential, potentially devastating rainfall is
expected later tonight through Thursday morning from
Hurricane Helene. There is the potential for another 5-12
inches of rainfall from Lake Hickory to the Catawba River
headwaters, with the highest totals along the Blue Ridge
Escarpment. This rainfall will occur on saturated soils and
excessive runoff into elevated streams will result in
potentially catastrophic inflows into the Catawba River
lakes.
Based on current rainfall forecasts and conditions, Duke
Energy expects Lake Rhodhiss to reach or exceed 110.0 feet
later Friday, which is 10.0 feet over full pond. The current
record pool elevation at Lake Rhodhiss is 110.10 feet which
occurred in August 1940. Major Flood Stage is 110.0 feet.
These lake levels may cause unprecedented, catastrophic
flooding of Lake Rhodhiss and possibly adjacent reaches of
the Catawba River.
- If the rainfall forecast verifies, Major flooding will be
possible along and near Lake Rhodhiss and a Flash Flood
Emergency may be issued. Residents are encouraged to heed
guidance from local officials and emergency management on any
potential impacts to property. Drivers are encouraged to
heed any barricades and avoid all flooded areas. This has
the potential to be a historic and extremely dangerous event.
Please stay weather aware and monitor lake levels and Duke
Energy projections closely for any changes.
