Disaster Analysis 2024

NASS can now monitor agricultural disasters in near real-time and provide quantitative assessments using remotely sensed data and geospatial techniques. This page provides disaster assessments in geospatial data format, reports, and metadata as available. A flood monitoring methodology paper is located here.

Midwest Floods: Late June 2024

During late June 2024, heavy rainfall across northwest Iowa, southwest Minnesota, and southeast South Dakota from June 20-22 resulted in rainfall totals exceeding 2 inches in most areas with widespread totals ranging from 5-10 inches. Some locations in southeast South Dakota and northwest Iowa reported 10-20 inches of rainfall. The event resulted in flash flooding, with record flooding observed at several river points and widespread, devastating floods in towns adjacent to rivers. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) produced an assessment on the extent of potential damage to agricultural land and activities 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 likely inundated areas by the flooding events in late June 2024. Inundated areas were then compared to the 2023 Cropland Data Layer (CDL) to estimate crops potentially affected by the floods.

Texas Wildfires: February 26 - March 2024

Beginning on February 26th (2024), emergency alerts were issued for multiple wildfires in northern Texas with potential to expand. The Smokehouse Creek incident was the largest of these wildfires and is the largest wildfire in Texas history with over one million acres of land burned. Damage reported in affected areas included hundreds of burned homes, thousands of livestock dead, and destruction of crops, grasslands, and ranching infrastructure. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) produced an assessment on the extent of potential damage to agricultural land and activities in the State of Texas from this event. Using the 2023 Cropland Data Layer and the WFIGS Current Interagency Fire Perimeters shapefile downloaded on March 7th (2024), NASS identified agricultural areas that may have been affected by the wildfires. Sampled burned areas were visually confirmed using Sentinel-2 Multi-Spectral Imagery (MSI) and WorldView-3, WorldView-2, and GeoEye-1 high resolution imagery (© 2023 Maxar and © 2024 Maxar).
