Observed data on Hurricane Helene: 100,000 buildings could be impacted

After making landfall, Helene continued moving inland, leaving a trail of flood and wind destruction in Florida, South and North Carolina, Georgia, and Tennessee through the weekend.

We delivered the first flood extent and depth analysis on September 28th, focusing on the west coast of Florida. Three more releases of our flood analysis have been produced since, covering additional areas in the Florida panhandle, Georgia, and the Southern Appalachians.

Based on THE latest data from our fourth ANALYSIS RELEASE, over 100,000 buildings have been impacted across Florida, North Carolina, Tennessee, Georgia, Virginia, South Carolina, and West Virginia, with at least 10,000 buildings inundated by over 60 inches (5+ feet;  152+ centimeters) of water.

Our team of flood experts continues to monitor the situation and analyze and process satellite data to provide near real-time flood extent and depth information to emergency management organizations, public authorities, and insurance companies in the region.
