"We're likely to get between 25mm and 35mm of rain, but it could be a lot more. There will be thunderstorms on Tuesday. Wednesday will start off dry and bright but come early afternoon, it will be very windy and wet and this will develop across the country," a Met Eireann spokesperson said.
"Leinster and Munster will be worst affected and there is every possibility of flooding late on Wednesday and into Thursday. Thursday will be very unsettled with more rain and showers. It will really be a poor weather week all told," he added.
A city council spokesperson said that additional staff are being put on standby. "Drainage are visiting and inspecting all river screens to ensure the drainage system can operate to maximum efficiency. Dublin Fire Brigade are on hand."
