A warning of tornadoes and flash floods along the coast of Texas has been issued due to the build up of a tropical storm.
The US National Hurricane Centre made the alert as Tropical Storm Bill built up strength 200 miles off land in the Gulf of Mexico.
Up to 12 inches of rainfall is forecast in eastern Texas with a risk of flooding along coastal areas. Winds gusting at up to 50mph are also expected.
The Foreign and Commonwealth Office issued a revised travel advisory to the US.
“Tropical Storm Bill is forecast to affect parts of Texas including the Gulf coastline, Houston and eastern Texas, as well as South Western Louisiana, from Tuesday 16 June,” the FCO said.
“High winds, heavy rain, storm surge and flash flooding is expected.
“Sporadic tornadoes are possible. You should listen to weather reports and follow the advice of local authorities.”
