Strong winds and heavy rain are being forecast for several western counties - including parts of the Atlantic coast - for later today and overnight.
Two separate status yellow weather warnings have been issued by Met Éireann.
A wind warning for Donegal, Galway, Mayo and Kerry comes into effect from from 3pm, and is valid until 11am tomorrow morning.
Forecasters are warning of south to southwest winds of 50 to 65 km/hr, with gusts of 90 to 110 km/hr, with the strongest winds on exposed coasts and hills.
They add that high seas and gales will lead to a risk of coastal flooding.
Meanwhile, a status yellow rainfall warning issued yesterday has been updated to include all of Connacht and Donegal.
