The awesome size of Hurricane Harvey has been recorded from space as it moves towards the United States.
Nasa has released a video filmed from the International Space Station showing the eye of the storm, now a Category 2 hurricane and predicted to rise to Category 3.
It is expected to make landfall in the US state of Texas late on Friday or early Saturday, local time, with up to three feet (90cms) of rain, 125 mph winds and 12-foot (3.6 metre) storm surges.
Forecasters have warned the storm poses a “grave risk”. It was upgraded from a tropical storm to a hurricane as conditions intensified.
The Nasa video was filmed just after 6pm EST on August 24.
Astronaut Randy Bresnik, who is one of six current ISS residents, tweeted a message of support for Texas on social media along with additional pictures of Hurricane Harvey.
