Two separate weather warnings have been issued by Met Eireann as winds associated with Storm Dudley look set to blast several areas.
A Status Orange wind alert for Donegal will be in effect from 9pm on Wednesday until 9am on Thursday.
The national forecaster says: "Westerly winds associated with Storm Dudley will reach mean speeds of 65 – 80km/h with damaging gusts of 100 – 130km/h, stronger on exposed coasts and on high ground.
"A combination of high tide and strong winds will lead to some coastal flooding."
A second wind warning for four counties was also issued on Monday.
The Status Yellow alert for Clare, Galway, Mayo and Donegal once again will be in place for 24 hours from 12pm on Wednesday until 12pm on Thursday.
Met Eireann says: "Westerly winds associated with Storm Dudley will reach mean speeds of 50 – 65km/h with damaging gusts of 80 – 110km/h, stronger on exposed coasts and on high ground.
"A combination of high tide and strong winds will lead to some coastal flooding."
It is expected that updates on both warnings will be issued on Tuesday morning.
Ireland could feel the impact of the storm later in the week as a jet stream moves towards the island.
Alan O'Reilly, from Carlow Weather, said: "Looking at latest weather model charts for wind gusts on Wednesday.
"The track and intensify remains uncertain but some models bringing damaging gusts into Northwest Ireland. A busy week of weather ahead with another storm possible on Friday."
Along with the strong winds, rain and even snow are on the cards for the nation in the days ahead.
Before then, it will be a mostly dry and sunny Valentine's Day with showers mostly dying out this afternoon. Highest temperatures 5 to 9C but feeling colder in a fresh to strong and gusty northwest wind.
A cold and frosty start tonight and along with the wind, there will be heavy rain, bringing a risk of localised flooding.
A forecaster said: "Tuesday, will have a mostly dry start with some sunshine with a moderate to fresh westerly wind backing southerly for a time. Temperatures in the afternoon will range between 5 and 8C and will rise Tuesday evening with the arrival of another spell of rain in to the southwest, falling as sleet initially in the north.
"Tuesday night will bring widespread and heavy rain with a further risk of flooding in places. The rain will clear eastwards overnight to showers with the chance of some sleet initially, particularly over hills and mountains. Temperatures later on Tuesday night will range between 9 and 11C in a strong westerly wind after a cold start.
"Wednesday will be fair at first, but with rain soon spreading from the west, clearing once again to showers later. Temperatures will be higher than usual for the time of year initially, it will turn cold with the clearing rain.
"Winds will increase strong to gale southwest to west with stormy conditions likely to develop in western and northern coastal counties and the risk of some coastal flooding due to wave overtopping.
"The severe winds will moderate on Thursday to bring a mainly dry day, though there'll be a few scattered rain or hail showers too, with a more persistent spell of rain later in the day and overnight. There's a chance of sleet and snow on hills and mountains overnight and at times to lower levels in the north. Becoming very windy again too.
"Friday will be a cold and very windy or stormy day with outbreaks of rain, sleet and hill snow."
