Get the brollies out folks, Met Éireann have issued a rainfall warning for Cork that comes into force at 4pm.
Forecasters expect 25 to 40 mm to fall, with the heaviest of the rain on high ground and mountains.
The status yellow warning, which also covers Kerry, will remain in place until at least 10am on Wednesday.
Isolated light showers in the early afternoon are expected to develop into more persistent rain as the day goes on. Heavy bursts are expected in places, particularly in western areas and will be accompanied by increased winds, which will become strong and gusty in coastal areas.
Persistent and locally heavy rain will continue overnight and will be accompanied by hill and coastal fog. Outbreaks of persistent and heavy rain will continue in south and southwest coastal areas on Wednesday morning but become patchy elsewhere.
Separately, Met Éireann have issued two status yellow marine warnings. Southerly winds will occasionally reach gale force tonight on all Irish coastal waters and on the Irish Sea.
