Forecaster Evelyn Cusack has warned of a weather system moving in from the Atlantic through Friday night and into Saturday.
Ms Cusack said on Thursday she expected “at least a status yellow, perhaps orange” weather warning to be issued by noon on Friday for the weekend.
"Our current models predict about 50mm, perhaps 80mm of rain," she said. "Impossible to predict where exactly but we're talking about parts of Munster, Connacht, perhaps into parts of Donegal as well."
