Event: Hurricane Debby - August 2024

Last Updated: August 26, 2024

Report File Name: Hurricane_Debby_2024_Aug23.pdf

Description: Hurricane Debby caused torrential rainfall and widespread flooding across the Southeastern U.S. in early August 2024. The storm made landfall near Steinhatchee, Florida on August 5, 2024 as a Category 1 storm, re-entered the Atlantic, and made second landfall in South Carolina on August 8. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) produced an assessment on the extent of potential damage to agricultural land from this event. A disaster assessment was conducted using available Sentinel-1 Synthetic Aperture Radar (SAR) and cloud-free Sentinel-2 Multi-Spectral Instrument (MSI) imagery coverage to identify inundated areas due to Hurricane Debby. Inundated areas were then compared to the 2023 Cropland Data Layer (CDL) to estimate crops potentially affected by the floods.
