Hurricane Harvey caused catastrophic flooding in south eastern Texas from 26 August, 2017. Over 40 deaths have been reported. As many as 7,000 homes were destroyed and as of 01 September, 35,000 people were still in temporary shelters.
According to the National Weather Service, 51.88 inches of rain were recorded at Cedar Bayou, Texas—the highest rainfall total for any storm in recorded U.S. history.
Satellite images from NASA below show the extent of the flooding.
The first image was acquired on 20 August, well before the Hurricane made landfall.
The second image was taken on 31 August, and shows vast areas of darker blue, indicating flood water around the Brazos and Colorado rivers, Houston, Galveston and eastwards towards the Beaumont and Port Arthur areas.
About the images, NASA says:
“On August 31, 2017, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired a false-color image (top) of extensive flooding along the Texas coast and around the Houston metropolitan area in the aftermath of Hurricane Harvey. A second image shows the same area on August 20, four days before the storm made landfall.
“Both images were made with a combination of visible and infrared light (MODIS bands 7-2-1) that highlights the presence of water on the ground. Water is generally dark blue or black in this type of image, but rivers also can appear light blue because they carry large amounts of suspended sediment. Turn on the image-comparison tool to spot areas that have been inundated by rainwater and coastal surges.”
