Strong winds and heavy showers are to hit counties Wexford, Clare, Cork, Kerry and Waterford over the next 24 hours with Met Eireann issuing a status yellow weather warning.
The warning is in place for these counties from 3.00pm today until 6.00pm tomorrow, Saturday.
Met Eireann has issued the warning as a deep Atlantic depression approaches the country from the southwest and will track east over Ireland on Friday night and early Saturday.
The depression is expected to generate some unseasonably strong southwesterly winds on its southern flank with the strongest winds affecting southwestern and southern coastal counties later Friday and early Saturday.
Some squalls of 80 or 90km/h are possible in coastal areas, Met Eireann has warned. Rough seas are also expected with some heavy thundery rain or showers at times also.
Sunday
Looking to the rest of the weekend, most of Sunday morning is forecast to be dry with some early sunshine but with cloud generally increasing.
In the afternoon rain will spread from the southwest of Munster, reaching all parts of the country by evening. Highest temperatures on Sunday will range between 17 or 18 degrees in freshening southerly winds.
Monday
It will brighten up on Monday morning and good sunshine is forecast in many places in the afternoon.
Met Eireann has said that showers will be well scattered and the second half of the day will be largely dry. Like Sunday, highest temperatures will range between 17 or 18 degrees in moderate westerly breezes.
Tuesday
A good deal of dry weather is forecast throughout the country on Tuesday, although some rain may affect south-Leinster and east-Munster during the morning.
Highest temperatures of 17 to 20 degrees in light breezes.
Wednesday
Current indications from Met Eireann suggest that Wednesday will be a mostly dry day with good sunshine and highest temperatures will range between 19 to 21 degrees.
