Met Éireann has issued a status orange wind warning for five counties in advance of Storm Barra hitting.
While the rest of the country has been issued a status yellow wind warning, Cork, Kerry, Limerick, Clare and Galway will be on orange alert from 6am on Tuesday and will be in place for 24 hours.
"On Tuesday and Tuesday night, due to Storm Barra, southerly winds, later becoming to northwesterly, will reach mean speeds of 65 to 80 km/hr with severe or damaging gusts of up to 130 Km/ hr, possibly higher in coastal areas.
"Disruption to power and travel are likely.
"High waves, high tides, heavy rain and storm surge will lead to wave overtopping and a significant possibility of coastal flooding," the forecaster said.
In Cork, the City Council Flood Assessment Team met today to assess the potential impacts the storm will have at high tide on Tuesday, which is at around 7.24am.
The council has advised people that it is likely that there will be localised flooding in some parts of the city.
It said that some roads and low-lying quays could be hit.
Morrison's Quay, Fr Matthew Quay, Trinity Bridge, Union Quay, Sharman Crawford Street, Wandesford Quay, Frenche's Quay, Proby's Quay, Crosses Green, Lavitt's Quay, Kyrl's Quay and potentially South Terrace, Rutland Street, Sawmill Street and South Mall have been highlighted as risk areas.
“Traffic restrictions may be in place at these locations, during these times [near high tide],” the council added.
“As forecasted weather and tidal conditions are variable at this time, Cork City Council is continuing to monitor the situation closely.”
The UK Met Office has also issued a status yellow wind warning for the North, from 9am on Tuesday until midnight.
A weather advisory for the country has also been issued, with it in place from 6am on Tuesday until 6pm on Wednesday.
The Atlantic depression and the associated gusts are likely to bring disruption due to power outages, fallen trees or branches or other debris.
"Travel disruption is likely at times due to strong winds, poor visibility, localised flooding and poor surface conditions due to hail, sleet or possible snow on high ground," said Met Éireann
Meanwhile, Sunday is set to see some good sunny spells with only a few isolated showers.
Cloud will increase from the west in the afternoon with rain developing on the west coast in the late evening.
Any rain will clear overnight with clear spells and scattered showers following. Temperatures will fall to as low as -1C tonight.
Monday is expected to be “a cold, bright and blustery day with sunny spells and showers, some falling as hail or sleet”.
