Our Earth-observing satellites, along with the cameras and crew of the International Space Station, are keeping a watchful eye over Hurricane Harvey as it churns in the Gulf of Mexico. When Hurricane Harvey blows ashore over coastal Texas on Friday night, it will likely be the first major hurricane to make landfall in the United States since 2005.
Above is a view of Harvey from NOAA’s GOES-East satellite captured on Aug. 25 at 10:07 a.m. EDT (1407 UTC) clearly showing the storm’s eye as Harvey nears landfall in the southeastern coast of Texas. As Hurricane Harvey continued to strengthen, we analyzed the storm’s rainfall, cloud heights and cloud top temperatures.
Above, the Global Precipitation Mission (GPM) core observatory satellite flew almost directly above intensifying Hurricane Harvey on August 24, 2017 at 6:30 p.m. EDT (2230 UTC) and we used the Microwave Imager instrument to peer through dense storm clouds to reveal the location of intense rainfall bands near the center of the hurricane.
And from the International Space Station, cameras were pointed towards Harvey as the orbiting laboratory passed overhead 250 miles above the Earth. The video above includes views from the space station recorded on August 24, 2017 at 6:15 p.m. Eastern Time.
The National Hurricane Center expects Harvey to be a category 3 storm on the Saffir-Simpson scale—with winds higher than 111 miles (179 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.
