Met Éireann has issued a status orange rain warning for three counties tomorrow.
The warning for Waterford, Wexford and Wicklow, where “some very intense rain is possible” comes into effect at 7am and will remain in place until midday.
Meanwhile, a status yellow rain warning for the whole country goes into effect tomorrow at 3am in the early hours of Monday and will remain in effect until 8pm.
Met Éireann said “heavy or thunderstorm rain” will lead to flooding for Sunday night and Monday.
Forecaster Aoife Kealy said: “What is happening is that a band of rain will move in overnight across the country and spread from the south-west and there will be some pretty heavy flooding in that rain and possibly some thunderstorm rain.
“It will rain intensely and that will cause flooding in places, especially in the districts under the orange warning, but the risk is really nationwide and that’s why there is the yellow rain warning.”
Ms Kealy said while the south and east will see the worst of the rain, there will be intense rain across the country.
“Especially for the time of year, the ground is pretty wet and saturated in most places, so heavy downpours cause flooding, so really just a little bit of extra care is needed, especially if you’re out on roads, too, in the counties where the yellow warning is present.
“The South and East will see a lot of the worst but it will be seen across the country so tomorrow will be a wet day wherever you are.
“There may be a light release later tomorrow in the South West but the rain will be followed by heavy showers there.”
The rest of the week will continue to be wet.
“Next week will be similar, there really is no sign of stable weather so we may see a continuation of that after tomorrow, with outbreaks of rain and showers and temperatures that will be close to the seasonal norm,” Ms Kealy said .
“In terms of precipitation, we are generally seeing rain, intermittent showers and possibly windy conditions as well and this will remain so throughout the week.
“The roads are the big things but I will only advise people to keep an eye on their local district council and seek advice from emergency management in a situation like this and they will have the best advice for any local area.”
