Warnings have also been issued to roads in eight other counties around the country.
After a night of heavy rain, snow, and sleet in parts of the country, drivers will have woken up on Saturday morning to find many of the roads in a much more treacherous state than usual.
AA Roadwatch have issued a list of warnings to several roads around the country following last night's bad weather, with particular attention paid to flooding in Cork.
This is the statement issued to drivers in Cork for Saturday morning:
"Flooding is affecting many secondary routes around Cork with care needed in most areas. The N25 is impossible at just east of Ovens due to flooding at Roadstones. Use an alternate route.
"To the west of the city, the Ballincollig/Coolore Rd (R608) is also impassable due to flooding. Flooding is also affecting the Glanmire to Knockraha Rd with this route impassable as well."
Additionally, the following roads in the following counties have also had warnings issued:
Wicklow: Gardaí say motorists should avoid the Sally Gap until further notice due to icy conditions.
Carlow/Kilkenny/Waterford: Poor driving conditions have been reported on the M9 between Carlow and Waterford due to slush with numerous collisions on this stretch. Take extra care and slow down if travelling in the area.
Wexford/Wicklow: Snow is affecting parts of Wicklow and north Wexford in particular, including stretches of the M11 around the Glen of the Downs, Wicklow Town, Gorey and Enniscorthy.
