Storm Barry

Trump approves Louisiana state of emergency

Storm Barry has been gathering speed over the Gulf of Mexico in recent days.

Officials say sustained wind speeds have grown to 50mph (80km/h) and may still reach hurricane strength by the time it makes landfall.

It is expected to bring a storm surge and heavy rainfall to the city of New Orleans - which has already seen thunderstorms and flash floods.

The National Weather Service warns that flooding from the slow-moving storm poses the greatest risk.
