After unleashing dozens of destructive tornadoes, a slow-moving storm system dumped heavy rain across the U.S. Midwest and Southeast in early April 2025. In some areas, 10-15 inches (25-38 centimeters) fell between April 1 and 6. According to hydrograph data from the National Weather Service, the rain fueled major floods on several tributaries of the Mississippi River, particularly within the Ohio River watershed in Kentucky, Illinois, and Indiana, and along the Black River and White River in Arkansas.
A break in the clouds on April 7, 2025, revealed to satellites the widespread flooding that spanned several states. The image above (right) was acquired by the VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-21 satellite. The other image, also acquired by VIIRS, shows the same area before the deluge.
Both images were assembled from false-color data using a combination of infrared and visible light (VIIRS bands M11-I2-I1). Floodwater appears navy or black; vegetation is bright green; and bare ground is brown. This band combination makes it easier to spot changes in river dimensions.
