Met Éireann has warned that Halloween Weekend will see very unsettled weather as a series of Atlantic weather systems pass close to Ireland.
A status yellow weather warning will come into effect on Saturday at 1.00am and last until 3.00 pm.
It will be very windy and stormy at times, with some severe and damaging gusts possible as well as very high seas.
Spells of heavy rain will lead to surface and river flooding, and coastal flooding is possible also due to the combination of low pressure, high tides and onshore winds.
The weather chiefs also issued a weather advisory which lasts from Friday evening to Monday evening.
Tomorrow, Friday, will be mostly dry though, with sunny spells developing and just the risk of an isolated shower. The highest afternoon temperatures will reach just 9 to 11 degrees, in light to moderate westerly or variable breezes.
