Hurricane Helene: NOAA Warns of Catastrophic Flooding as Category 4 Storm Approaches Florida

As Hurricane Helene barrels towards Florida’s northwest coast, the National Oceanic and Atmospheric Administration (NOAA) is sounding the alarm on the potential for catastrophic inland flooding that could continue long after landfall.

“We urge the news media to continue focusing the public’s attention on the major impacts from inland flooding expected along the path of Helene well after landfall,” NOAA emphasized in a rare press release.

Helene, an unusually large storm with a wind field extending 345 miles from its center, is predicted to make landfall Thursday evening as a major hurricane. The National Hurricane Center’s Wednesday afternoon update forecasts Helene to reach Category 4 strength, with sustained winds exceeding 130 mph within 24 hours.

The storm’s impact will stretch far beyond the coast. NOAA’s National Weather Service warns that Helene’s flooding rainfall and high winds are expected to travel hundreds of miles inland. The southern Appalachians region could see up to 18 inches of rain by Friday.

“Catastrophic and life-threatening flash and urban flooding, including landslides, is expected across portions of the southern Appalachians through Friday,” the National Hurricane Center stated. Urban areas at risk include Tallahassee, metro Atlanta, and Asheville.

The danger is compounded by already saturated ground and high river levels in these areas. “Extreme rainfall rates across the mountainous terrain of the southern Appalachians will likely inundate communities in its path with flash floods, landslides, and cause extensive river and stream flooding,” NOAA warned.

Coastal areas face their own perils. A storm surge of up to 20 feet above ground level is predicted for portions of the Florida Big Bend coast, along with destructive waves. Residents in affected areas are urged to follow evacuation orders from local officials.

NOAA emphasizes that flooding from extreme rainfall has been the deadliest direct cause of tropical cyclone fatalities in the U.S. over the past decade. As Helene approaches, the agency stresses the importance of preparedness and heeding official warnings to minimize loss of life and property damage.
