A Status Orange wind warning has been issued for seven counties for Friday, when Storm Eunice is set to hit the country.
Met Éireann issued the warnings for Clare, Cork, Kerry, Limerick, Waterford, Galway and Wexford, saying the storm will bring severe and potentially damaging winds, gusting up to 130km/h, higher in exposed areas.
The forecaster added that some disruption is expected along with a possibility of coastal flooding.
The warning will be in place from 5am on Friday to 11am on Friday.
A yellow wind warning for Ireland is in place across the country until midnight tonight, with a risk of coastal flooding and also some spot flooding in areas from heavy rain, due to Storm Dudley.
On Friday, a Status Yellow wind, rain and snow warning will be in place from 1am to 3pm.

The department also said Storm Eunice will bring "disruptive and challenging weather conditions on Friday, with impacts from strong winds, heavy rain and snow expected".

Meteorologist Matthew Martin said they are "keeping a very close eye on the forecast for Friday as Storm Eunice is expected to bring some challenging weather conditions, especially on Friday morning as strong winds, heavy rain and snow moves across the country".
"At the moment it looks like northern and western areas are most likely to see the heaviest snow falls, with southern areas expected to see the strongest winds, however we're still a few days ahead and the details of when and where are likely to change.
"With this in mind, we’re urging people to keep a very close eye on the forecast and warnings for their area as these may change in the coming days."

Meteorologist Gerry Murphy said Storm Dudley will generate strong westerly winds, bringing damaging gusts.
Speaking on RTÉ's Today with Claire Byrne, Mr Murphy said: "It's a depression that's going to move to the north of the country, and it's going to generate very strong westerly winds right across the country really from around midday onwards."
He said there will be a high tide at around 5pm before a lull tomorrow ahead of Storm Eunice, which will also produce very high winds.
"Another significant aspect of Eunice is the fact that it's going to bring some heavy rain sleet, but also some snow.
"So there is the potential for lying snow, especially over parts of Connacht and Ulster as we go through the early hours of Thursday on into Friday," he said.
Mr Murphy said the potential for disruption Storm Eunice will be "more vicious" as it will also bring rain, sleet, and snow and there is a good risk of travel disruption due to high winds on Friday morning, coupled with sleet and snow.
Once Storm Eunice clears, cold, showery weather will follow and any snow that has fallen will take a while to melt, he added.
Members of the Government committee that coordinates responses to emergencies met yesterday in preparation for the forthcoming storms.
Its Crisis Management Team will continue to liaise with Met Éireann to monitor the evolving weather patterns and intends to conduct further meetings of the group over the coming days.
The Road Safety Authority has appealed to road users to exercise caution over the coming days.
