Met Eireann has issued a status orange weather warning for one county to come into effect on Monday as Ireland is set to be battered with high winds and heavy rain over the next two days.
The orange alert for Donegal will come into effect at 1am Monday and last until 7am.
Met Eireann said: "Severe west to northwest winds with some damaging gusts are possible on Sunday night, please see yellow wind warning for Donegal where there is further details and associated risks."
A Status Yellow Rain warning for Cavan, Donegal, Leitrim, Mayo and Sligo will remain in place until 6pm Sunday as persistent rain followed by heavy showers will lead to localised flooding in places.
A Status Yellow Wind warning for Clare, Cork, Kerry, Limerick, Donegal, Connacht, Leinster, Cavan, Monaghan, Tipperary and Waterford
is also in place from 5am Sunday until 9am Monday with very strong southwesterly winds and some severe gusts expected.
The winds will later veer west to northwest on Sunday afternoon through early Monday morning.
Strong winds, surge and phenomenal waves may lead to wave overtopping, particularly at times of high water, and coastal flooding is possible along coasts.
Meanwhile, tonight will be a wet night with widespread outbreaks of rain, turning heavy in the north and west with localised flooding possible.
It will become increasingly windy, with southwest winds increasing strong and gusty with gales along Atlantic coasts.
While it will be cold initially in Ulster, milder air will spread from the south, with temperatures rising overnight to between 8 and 10 degrees.
Looking ahead to Sunday, Met Eireann said: "Very windy and wet on Sunday with strong to near gale force southwest winds and some severe gusts.
"Rain will be heavy at times leading to localised flooding, before clearing southeastwards to frequent showers through the afternoon.
"Some of the showers will be heavy with isolated thunderstorms and hail possible. During the afternoon winds will veer west to northwest and they will be persistent strong to near gale force winds, with severe gusts especially along western and northern coasts, with very high seas also leading to some coastal flooding.
"While it will be mild during the morning, it will turn much colder from the northwest after the rain clears with highest afternoon temperatures of 4 to 8 degrees."
Monday will get off to a windy to start with strong northwest winds. However, winds will ease through the afternoon as they begin to back southwesterly.
Scattered showers will mainly affect the northern half of the country, with a good deal of dry weather and sunny spells in the south. Showers will die out through the afternoon as cloud thickens.
Highest temperatures of 9 to 11 degrees.
