Speaking on Morning Ireland on RTE Radio One, she said: "It is a miserable start to the day everywhere.
"There is widespread heavy rain and localised flooding, and a high volume of rain recorded overnight.
"Highs today will be 9-14 celsius.
"It is much colder outside Leinster and Munster, with sleet expected for some time over Connacht and Ulster.
"As the rain begins to ease off, it will turn colder everywhere.
"We can expect some winter flurries early on tomorrow as the cold weather hits.
