The destructive path of Hurricane Harvey began to take shape on Sunday, with a striking collection of aerial photographs laying bare its damage for the first time.
Entire streets lay submerged in water where abandoned cars bobbed alongside rescue boats taking residents to safety.
Five people are feared dead and dozens are injured after 130mph winds and unprecedented floods swept through the southeast pocket of the state on Friday and Saturday.
There is more rain on the way - another 50 inches - and emergency response teams have been stretched to their limit.
On Sunday, as thousands fled their homes in kayaks and swam through the watery streets, FEMA, the Federal Emergency Management Agency, revealed it would take the area years to recover from the storm which is the worst this decade.
Harvey has been downgraded from a Category 4 hurricane to a tropical storm but its threat is still imminent. Authorities are now fearing its second deadly phase - the floods.

Courtesy of Weather Channel weather producer, Matthew Sitkowski, here is a photo of what Houston's East Loop at Market Street on the I-610 looks like right now. As Sitkowski says, "this image and the forecast of what is still to fall.... This is surreal." He is right: we added a photo of the same location from February 2016 to show the "before and after." Here is the result:
By the time the storm ends, 40 inches of rain (a number which now appears conservative) is expected to fall and an estimated $40 billion worth of damage left behind. Putting the number in context, Hurricane Katrina cost $108 billion, mostly as a result of flooding to New Orleans.
