Heavy rainfall is causing treacherous driving conditions along the east coast, with a warning for spot flooding in places.
The Met Office has a number of advisories in place, with a gale warning and a small craft warning in operation.
Forecaster Liz Walsh says it is not great if you are heading home after the bank holiday weekend.
She said: "There is bound to be some surface flooding, definitely in the Wexford area but also from Waterford up towards Wicklow and into the Dublin area as well."
Heavy rainfall is bringing a miserable end to the Easter bank holiday.
Several Met Office warnings are in place and there are alerts about treacherous driving conditions and spot flooding in places.

There is also a gale warning and small craft warning in operation, with easterly winds reaching force 6 at times today.
Met Eireann's Liz Walsh says the east coast is worst affected.
She said: "We've got a low pressure system moving into the Irish Sea and it has got rain bands wrapped around it and these rain bands are circling around bringing showery rain across the eastern Leinster area, some showers also further north and west as well."
