Cork City Council has advised householders and businesses to "take precautionary measures to protect their property" during "very high" astronomical spring tides later this week.
The spring tides will last from Wednesday until Sunday, and in addition a tidal surge is also forecast to occur during this time.
These factors will result in higher tide levels than the natural tide levels, and therefore the council has advised locals to put their tidal barriers in place before the high tide on Wednesday, Thursday, and Friday evening, and leave them in place overnight.
According to the council, it is "highly likely" that road ponding and flooding may occur in the low-lying areas of the city including Morrison’s Quay, Fr Mathew Quay, Fr Mathew Street, Union Quay, Trinity Bridge, South Terrace, Rutland Street, Sawmill Street, Crosses Green, Sharman Crawford St, Wandesford Quay, and South Mall.
In addition, road flooding will also likely occur on Kyrls Quay, Lavitts Quay, Lapps Quay, Proby’s Quay, French’s Quay, and Sullivan’s Quay.
Cork City Council said it will continue to monitor the situation, and further advice will be issued if there are any changes.
Spring tides occur during full moons, when the Moon is between the Earth and the Sun, with the added gravitational effect making the tides bigger.
The tides are expected to be high from 5pm on Wednesday.
Meanwhile, Met Éireann has issued a status yellow rainfall warning for three counties in the southeast. The warning for Carlow, Wexford, and Wicklow, came into effect at 6pm on Tuesday and will run until midnight.
Under the warning, Met Éireann is predicting "heavy rain with embedded thunderstorms". Possible impacts may include localised flooding, travel disruption, and hazardous travelling conditions.
More generally, Tuesday night will be cloudy with outbreaks of heavy rain. There will also be a chance of isolated thunderstorms, but it will be "mild and humid" with temperatures not falling below 11C to 14C.
Wednesday morning will be "mostly cloudy" with "scattered outbreaks of rain" which will linger throughout the day. Highest temperatures of 15C to 18C are expected.
Thursday will be "mild with sunny spells and scattered showers" but some will turn heavy with a "chance of thunder". The showers will become isolated by evening, and highest temperatures of 13C to 16C are predicted.
On Friday, it will be "wet and breezy" as rain tracks eastwards across the country, "turning heavy at times." But a clearance to "sunny spells and isolated showers in the west later in the afternoon will extend to all areas in the evening."
Looking ahead to the weekend, there is "uncertainty in the forecast", but at the moment it looks like there will be a "spell of wet and windy weather" on Saturday night and for a time on Sunday.
