Galway v Offaly, Westmeath v Longford and Wexford v Tipperary have been added to the list of today's Allianz Football League fixtures postponed following inspections.
Sligo's home clash with Cavan also fell victim to the bad weather this morning.
The CCCC will confirm re-fixture details in the coming days.
However, the surface at Derry's Owenbeg passed a second pitch inspection this morning and their game against Cork survives the atrocious weather conditions.
Meanwhile, an alternative venue has been sought for the Limerick-Louth tie which will now be played at UL's North Campus while Leitrim v London has been moved to the Connacht GAA Centre of Excellence all-weather 3G outdoor pitch.
All other fixtures are expected to go ahead as planned.
