It is hoped the flypast could take place on Sunday

A World War II Spitfire, Hurricane and Lancaster bomber due to fly over the White Cliffs of Dover have been grounded because of high winds.
The Battle of Britain memorial flypast on Saturday was to be part of a weekend of events for Dover Regatta.
The celebrations also mark the 400th anniversary of Dover Harbour Board.
A harbour board spokeswoman said weather conditions at Kent's Manston airport, where the planes are based, had forced the flypast to be cancelled.
It was hoped it could take place on Sunday instead.
Free event
"They will be doing a bit of a dogfight over the White Cliffs so that should be pretty special," said Bill Fawcus, of Dover Sea Ports Development Trust.
Large crowds are expected on Sunday for the displays, which also feature the Red Arrows, and a park and ride system will be in place to take visitors from the Jubilee Way roundabout to Market Square.
"It is a free event so anyone coming can roll up and enjoy a whole range of attractions and displays and activities for all the family," said Mr Fawcus.
This year's regatta features a new event - international K-Class powerboat racing, which will take place on both days.
Dover Harbour Board was established by royal charter under King James I to maintain, administer and improve the port.
