Met Éireann has updated its weather warning for Galway and other counties along the Atlantic coast, which is now in effect until tomorrow morning.
The forecasters say spells of rain will be heavy and persistent at times this evening and overnight, especially on hills and mountains.
The heavy downpours could lead to localised flooding and travel disruption in counties where the warning is in place.
Cavan, Clare, Cork, Donegal, Kerry, Leitrim, Limerick, Mayo, Roscommon, Sligo, and Tipperary are also affected by the warning, which came into effect at 5pm this afternoon.
The status yellow warning is set to be lifted at 6am on Wednesday morning.
