Three weather warnings have been issued by Met Éireann as Storm Henry brings strong winds and rain to much of the country.
Southwest to west winds will reach speeds of between 65-80km/h with gusts of between 110-130km/h up to 4am on Tuesday.
Winds will be at their strongest along the coasts.
A Status Orange wind warning has been issued for counties Donegal, Galway, Leitrim, Mayo, Sligo, Clare, Cork, Kerry, and Limerick.

The Road Safety Authority is advising road users to take extreme care in the forecast weather.

Meanwhile, a group of more than 30 families have called on the Minister for Agriculture to take urgent steps to allow them to drain a lake near Lanesboro in Co Longford into the River Shannon.
The families, who have been isolated for almost nine weeks due to flooding, say the turlough which is threatening to flood their homes is less than two kilometres from Lough Ree.
Residents at Fortwilliam and Lismacmanus say unless the water is released, houses may be flooded and farming land left under water until at least the middle of May.
Parents of children attending local schools have been unable to use cars or 4x4s for more than five weeks and pumps are being used on a 24-hour basis to protect houses from flooding.
There are still 20 local roads closed and flooded in Co Longford, mainly because of natural lakes, known as turloughs, in the south of the county.
Many of these lakes are several miles away from the Shannon but while the levels on the river have gone down, the water levels on the turlough have gone up in the last five weeks.
Members of Longford Civil Defence are providing generators and sandbags for the families whose homes are surrounded by flooding.
