A weather warning has been issued by Met Eireann for Friday, with heavy rain likely to cause difficult driving conditions and possible flooding.
The Status Yellow rain warning for Galway and all of Connacht, Leinster, Munster, Cavan, and Monaghan will be in effect from 2am to 7pm tomorrow.
There will be spells of very heavy rain, Met Eireann has warned, with the weather turning blustery at times as well, especially on the south and east coasts.
The rain will possibly cause flooding, poor visibility, and difficult driving conditions, the forecaster has said.
Today in Galway, light showers will become heavier and more widespread as the day progresses, with light to moderate southerly winds.
On the weekend, more rain is expected on Saturday, along with blustery westerly winds.
Conditions will improve on Sunday, however, with some sunny spells mixed in with light showers.
