Concerts by British bands Coldplay and Oasis at an open air music venue in Texas have been postponed ahead of Hurricane Rita.
Coldplay are due to play in Texas as part of an extensive US tour
The bands were due to play at the Cynthia Woods Mitchell Pavilion in Houston in separate shows this weekend.
The venue is citing safety concerns as the reason for the postponements.
Meanwhile, organisers of the outdoor Austin City Limits festival, which both bands are due to play before a crowd of 65,000, say the event will go ahead.
Coldplay had been due to headline a show at the Houston venue on Saturday, with Oasis playing the following night.
A concert by US rock band Journey, scheduled for Friday, has also been postponed.
An announcement on venue's website said: "This action is taken in the best interest and safety of the fans, artists and staff in the face of Hurricane Rita."
The storm, which meteorologists say could be one of the most powerful seen on the US mainland, is heading towards Texas with winds of 165mph (265km/h).
President George Bush has declared a state of emergency in Texas and neighbouring Louisiana.
Coldplay and Oasis are among the headline acts for the three-day festival which begins in Austin on Friday, along with US acts like country stars Lyle Lovett and Lucinda Williams.
Bloc Party, Keane, Kasabian and Franz Ferdinand are among the other British acts booked to perform.
Oasis are due to tour the US until 3 October
A festival spokeswoman told the BBC news website that organisers were being advised by experts and were keeping "a very close watch on the weather".
"If weather conditions appear to present any kind of danger to fans, musicians or crew, we are prepared to make the necessary adjustments to maintain safety," she said.
"Until then, the festival is on, rain or shine."
One concert-goer, who has a three day pass to the festival, said: "The organisers have said they won't cancel, rain or shine.
"Sixty-five thousand people at a concert in a hurricane is going to be awesome."
