The approach of Storm Brendan has resulted in Met Eireann extending the Status Orange wind warning for the whole country.
Initially, the Status Orange wind warning was put in place for 11 counties on the west and south coasts of Ireland while a Status Yellow warning was issued for Leinster, Munster, Cavan, Monaghan and Roscommon.
That has now changed and the entire country will be under a Status Orange warning from Monday morning.
A Met Eireann spokesperson updated: "As Storm Brendan tracks to the northwest of Ireland, southerly winds will reach mean speeds of 50 to 70 km/h with gusts of 100 to 120 km/h, higher in exposed areas.
"There is a significant risk of coastal flooding due to the combination of high spring tides and storm surge."

The wind warning for Leinster, Cavan, Monaghan, Clare, Cork, Limerick, Tipperary and Waterford is valid from 8am on Monday morning until 3pm that afternoon.
The wind warning for Connacht, Donegal and Kerry is valid from 5am on Monday morning until 9pm Monday evening.
The national forecast for Monday reads as follows: "Monday will be extremely windy or stormy, as storm Brendan tracks to the northwest of the country. Strong to gale force southerly winds will extend countrywide during the morning, with severe and damaging gusts, especially on southern, western and northwestern coasts.
"Heavy rain will extend from the Atlantic also, possibly thundery in places. There is a significant risk of coastal flooding due to a combination of strong winds, high spring tides and storm surge.
"Clearer conditions, with squally showers of rain and hail, will follow from the west during the afternoon and early evening, but there is a continuing risk of thunder. Winds will veer southwesterly with the clearance, easing a little in most areas, but it will remain stormy on western coasts, with further severe gusts. Maximum temperatures 7 to 10 degrees."
