Eyewitnesses said the hole has increased in size and part of the pavement has now eroded. About two weeks' worth of rain fell in about six hours in the city on Friday.
Geology specialist Dr Nigel Cassidy, of Keele University, said: "There is soft sediment in there [under the road] and when it gets wet, as we had with this rainfall, the sediment gets weaker.

Manchester City Council said the road could remain closed over the weekend "depending on the extent of the issue".
