The warning will be in effect for Donegal, Galway, Leitrim, Mayo, Sligo, Clare, Cork and Kerry between 3pm this afternoon and 3am tomorrow morning.
Met Éireann is forecasting mean wind speeds of 65 to 80 km/h and gusts of up to 120 km/hr.
The winds are set to be strongest near coasts, leading to a risk of flooding.

The Road Safety Authority is warning motorists to drive with care in the slippery conditions.
Meanwhile, a Wind Warning is in place for all coastal counties from Donegal to Cork with westerly winds gusting up to 110 kilometres per hour, and possibly higher on exposed coasts this afternoon.
Atlantic counties are also subject to a coastal flood warning, due to high or very high seas between now and Thursday morning.
