Oldham Athletic's game at Rochdale has been postponed due to a waterlogged pitch.
The match official conducted a pitch inspection at 10am, with a second inspection carried out at 10.30am in the hope of an improvement in the weather.
But the derby has been called off following a spell of heavy rainfall overnight and this morning, with continued rain forecast due to Storm Bert.
A statement from Rochdale said: "This afternoon’s Vanarama National League match at home to Oldham Athletic has been postponed.
"The frost covers had been in place all week and did their job, with the pitch in a playable condition when they were removed on Friday afternoon. However, frost covers do not prevent rainfall from affecting the pitch.
"The overnight and morning rain means the pitch is now waterlogged, with a forecast of continued heavy rain throughout the day leading the match official to postpone the fixture."
Rochdale's co-chairman Simon Gauge said: “I would like to thank both the ground staff and wider staff at the club for all of their efforts this week in the most challenging of weather conditions to try and get the most anticipated derby for quite some time on.
“Unfortunately, since 5am this morning, the combination of heavy snow and rain has left certain parts of the pitch in an unplayable condition.”
A rearranged date for the game will be confirmed in due course.
