Post-Tropical Cyclone Helene Discussion Number  19
NWS Weather Prediction Center College Park MD   AL092024
1000 PM CDT Fri Sep 27 2024

KEY MESSAGES:

1. Widespread significant river flooding is ongoing across the 
southern Appalachians, some of which are record-breaking. 
Conditions will begin to improve Friday night and on Saturday 
following the catastrophic flooding over the past two days.

2. There is a possibility of long-duration power outages in
portions of the southeast U.S. If you use a generator, be sure it
is placed outside at least 20 feet away from doors, windows, and
garages to avoid deadly carbon monoxide poisoning.

3. Use caution after the system passes as deadly hazards remain
including downed power lines and flooded areas.
