Met Eireann has issued three weather warnings, including two Status Orange alerts for 11 counties, as the west and northwest braces for the onslaught of Storm Brendan.
The national forecaster revealed the west coast is set to be lashed by high winds gusting up to 130km/h on Monday.
A Status Orange wind warning for Donegal, Galway, Leitrim, Mayo and Sligo will come into effect at 7am on Monday, January 13, and will expire at midnight that night.
A forecaster said: "As Storm Brendan tracks to the northwest of Ireland, southerly winds veering southwesterly will reach mean speeds of 65 to 80 km/h with gusts of 110 to 130 km/h, highest in coastal areas.
"There is a significant risk of coastal flooding due to the combination of high spring tides and storm surge."
Meanwhile, a second Status Orange wind alert was issued for counties Wexford, Clare, Cork, Kerry, Limerick and Waterford.
The warning is valid from 7am on Monday and will expire at 3pm that afternoon.
And a third less severe Status Yellow warning covers the rest of the country.
This wind warning covers counties Dublin, Carlow, Kildare, Kilkenny, Laois, Longford, Louth, Wicklow, Offaly, Westmeath, Meath, Cavan, Monaghan, Roscommon and Tipperary.
It will come into effect at 7am on Monday and remain in place until midnight.
A forecaster said: "Southerly winds veering southwesterly will reach mean speeds of 50 to 65 km/h with gusts of 90 to 110 km/h, highest in coastal areas."
Earlier today, the national forecaster has issued a weather advisory warning of "unsettled" conditions ahead.
It reads: "We are entering a period of very unsettled weather. Further warnings for strong winds and rainfall are likely to be issued in the coming days.
"A combination of spring tides and gales may lead to coastal flooding at times."
