• Mitch Landrieu says: 'We are at risk if we have a massive rain event'
• Fire at power station on Thursday reduces city's ability to drain stormwater

With heavy rains forecast for Thursday, New Orleans is in a "vulnerable position" following a fire at one of the power stations that runs the city's flood-control water pumps, its mayor has said.

"We are at risk if we have a massive rain event," Mitch Landrieu said at an emergency 3am press conference on Thursday.
