Householders and motorists were bracing themselves today for gale force winds which could cause flooding and bring down trees.
Gusts of up to 130km/h are expected to sweep across the country, with west and north due to be battered by the remnants of Hurricane Katia which is crossing the Atlantic Ocean.
Met Eireann warned there will also be exceptionally high seas along the western seaboard which, in conjunction with high spring tides and heavy showers, may cause coastal flooding in prone locations.
AA Roadwatch advised motorists to take particular care on exposed roads, especially in the coastal counties of Connacht and Ulster, and in high-sided vehicles.
Irish Ferries Swift Sailings from Dublin to Holyhead have been cancelled because of poor weather conditions on the Irish sea.
Forecasters said winds speeds will range from 50 to 80km/h - with gusts ranging 90 to 130 km/h - overnight and tomorrow.
Met Eireann also forecast strong south-west winds on Monday and Tuesday, when there will also be a risk of isolated thunderstorms.
“Winds will ease further during Wednesday,” it added.
The Irish Coast Guard also advised members of the public to take care during the stormy conditions, particularly around the coast and in exposed areas.
It urged people to avoid sea or water-based activities and taking dangerous cliff walks alone.
“There is safety in numbers,” it said.
“Always let someone know when and where you are going, and when you are expected to return.
“Stay well away from cliff edges, both top and bottom. Don’t attempt to rescue people or pets if they fell over a cliff edge.”
