A storm lasting about 30 minutes wreaked $18m in damage and left tens of thousands without power in the US city

The storm that hit the Memphis, Tennessee, area on 22 August lingered for only about half an hour. But the destruction it left was lasting: $18m in damages, fallen trees and more than 100,000 people without power.

Amber Sherman was one of the east Memphis residents who lost power, but her first thoughts were of her neighbors. “My main thought was that the power’s going to be out for a while and people aren’t prepared for that and it’s very hot outside,” Sherman, a coordinator for Black Voters Matter (BVM) in Memphis, said. Days after the storm, a series of rain showers and thunderstorms known as a bow echo storm, the high in Memphis was 91F (32.8C). Tens of thousands of households were still without power.

It’s been 10 days since the floodwater receded from Cambridge City’s main street and yet signs of disaster are all around.

Abandoned cars, toilets and bathtubs are strewn across parks and side streets on a recent visit to the city. Garages have been lifted from their foundations and moved by the rushing water. Dumpsters up and down the street are overflowing with people’s belongings, with red paint sprayed on homes indicating which houses have been cleared by water rescue teams.
