United's Carling Cup semi-final first leg against Manchester City has been postponed.
The Reds were due at Eastlands on Wednesday night, but heavy snow in the north west means the game has been rearranged to Tuesday 19 January.
The second leg, originally scheduled for Tuesday 19 January at Old Trafford, will now take place on Wednesday 27 January.
A statement on City's official website said: "After discussions with the relevant parties including Greater Manchester Police, the Safety Advisory Committee, the Football League and Manchester United, the decision was unanimously reached that the game should be re-scheduled due to safety concerns, particularly with regard to travel for supporters.
"The North West Ambulance Service has declared the region as a major incident area and Greater Manchester Police are now responding to emergency calls only. The Met Office was also consulted and with projected temperatures of minus four tonight, due to drop to minus six on Wednesday evening, all parties agreed a postponement was the only solution."
As a result of the rearranged Carling Cup games, United's Barclays Premier League home game against Hull City (scheduled for 26 January) has been postponed. A new date for this fixture has yet to be decided.
