Met Éireann said: "Increasingly windy overnight, with south to southwest winds increasing strong to gale force and gusty by morning.
"Potentially damaging gusts may occur near Atlantic coasts towards dawn, with the threat of coastal flooding due to very high seas."
Overall, Friday will be a very windy day with strong to gale-force southwesterly winds gradually veering westerly.
Saturday will start windy with further scattered showers.
The forecaster added: "The showers will be most frequent in the west and north, with an ongoing risk of hail and thunder, but they will gradually become more isolated towards evening. Highest temperatures will be around 6C to 9C.
"Strong and gusty southwesterly winds will gradually abate. Showers will continue to affect Atlantic coastal counties on Saturday night, but it will be largely dry with clear spells elsewhere.
"Light southwest winds will freshen and veer westerly overnight, helping to mitigate the risk of frost and icy patches."
