High winds and storm tides caused misery with the River Lee breaking its banks in Cork for the second time in three days.
The combination of high tides, torrential rainfall and south-westerly winds resulted in flooding throughout low-lying parts of Cork city centre from 7.20am.
Flooding resulted in lane closures along several city centre roads with heavy flooding on Fr Mathew Quay, South Mall, the Lower Glanmire Road, Morrisson’s Quay, Union Quay, Lavitts Quay and Wandsford Quay.
Officials said the flooding is the most severe since entire parts of the city centre were left underwater last month with the South Mall particularly badly hit.
The city and county remains on ‘orange alert’ for flooding again this afternoon after the Atlantic weather front hitting the south-west brought a combination of winds gusting to 120kph and torrential rainfall.
There have been no reports of major flood-related damage to retail or residential premises.
However, high winds brought down a number of trees in the Cobh, Mallow and Fermoy areas.
Flooding was also reported in Bandon, Skibbereen, Mallow and Carrigaline as the county endured torrential rainfall for over 12 hours.
Flood defences again held in Mallow and Fermoy where water levels in the River Blackwater remain exceptionally high.
Spot flooding was reported on virtually all county roads with several accidents in Clondulane and Macroom blamed on flooded roads.
Gardai and AA Roadwatch urged motorists to drive with extreme care given the treacherous road conditions.
Several hundred acres of farmland in the Lee, Blackwater and Funcheon river valleys remain under water.
High winds also made the work of the emergency services extremely difficult.
Several hundred homes in mid-Cork lost electricity as the winds damaged power lines.
Cork Airport urged passengers to check their flight details as due to weather conditions a number of flights were cancelled over the weekend.
Aer Lingus services to Heathrow have been hit with the 11.50am and 8pm flights cancelled on Saturday.
Walkers were also urged to avoid exposed coastal areas of west and east Cork due to the danger posed by waves and winds which are expected to gust close to Hurricane Force.
