When Hurricane Harvey blows ashore over coastal Texas on Friday night, it will likely be the first major hurricane (category 3 or stronger) to make landfall in the United States since 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image of the rapidly intensifying storm at 11:24 a.m. Central Daylight Time (16:45 Universal Time) on August 24, 2017.
The National Hurricane Center expects Harvey to be a category 3 storm on the Saffir-Simpson scale—with winds exceeding 110 miles (180 kilometers) per hour—when it makes landfall. It will likely produce a storm surge of 6 to 12 feet (2 to 4 meters) and drop between 15 and 25 inches (38 and 63 centimeters) of rain in some areas—enough to produce life-threatening flash floods.
