KEEP your raincoat and umbrella close at hand, as the next few days will be wet with the possibility of some flooding.
Met Eireann says that heavy and thundery rain will hit the country until at least late tomorrow evening, with localised flooding likely along the south and south-west coasts.
But there'll be no need to wrap up warm, as temperatures are expected to be in the high teens.
Forecaster Deirdre Lowe said that any break in the rain would result in largely pleasant weather for this time of the year.
"Up until Thursday evening and night, there will be pulses of rain, some heavy and thundery, and there's likely to be flooding in places, particularly in the south," she said.
"It will be humid with mist and fog, and mild. It will clear away on Thursday evening and it will be brighter from Friday with sunny showers.
"Temperatures will be pretty good and into the high teens. Generally speaking you're looking at temperatures of 17C, and they won't fall that much at night. From Friday, they look between 15-17C which should remain the same until Sunday.
"But between now and late on Thursday, there's going to be a lot of rain. There will be localised flooding, and the south west and south coast will be most at risk. The north west will also have pulses of heavy rain."
Met Eireann said while temperatures over the coming days would be high, persistent, fresh southeast winds would keep temperatures around normal, but it would feel cooler in the wet conditions.
The forecast is in stark contrast to September where rainfall was below average everywhere.
The latest monthly weather summary from Met Eireann says the north and north midlands were the driest parts of the country, with monthly rainfall values at their lowest in some stations for the past 11 years.
Conversely, Sherkin Island recorded the wettest day with 37.6mm of rain on September 28, nearly half its monthly total and the wettest September day since 2006.
"The majority of stations recorded between eight and 13 wet days, a below average amount, with Malin Head measuring nine wet days, six days below its average and its lowest amount in 11 years," Met Eireann said.
Temperatures were about average, but Claremorris in Mayo had the warmest average with 13.7C, 1C above average, and its warmest September in seven years. The highest maximum temperature recorded was at Oak Park in Carlow on the 21st with 23.9C.
