Met Éireann has issued two Status Orange wind warnings ahead of Storm Aiden, which is set to hit the country this Halloween (tomorrow, Saturday, October 31).

Both alerts were issued by the national meteorological office at 10:00am this morning (Friday, October 30).

The first orange warning will come into effect at 5:00am tomorrow morning and remain in place until 10:00am.

It will affect counties: Carlow; Kilkenny; Wexford; Wicklow; Cork; Kerry; and Waterford.

Meanwhile, the second alert will be valid from 8:00am tomorrow through to 4:00pm, and will affect counties: Donegal; Galway; Mayo; Sligo; and Clare.

In all affected counties under both warnings, Met Éireann warns that, on Saturday morning and afternoon, strong southwest to west winds associated with Storm Aiden will reach mean speeds of 65 to 80kph, with severe and damaging gusts of 100 to 130kph.

During this time, the rest of the country will be under a Status Yellow wind warning, with the alert valid from 1:00am tomorrow morning through to 3:00pm tomorrow afternoon.

In these areas, strong to gale force southerly winds will veer westerly. Some severe gusts are possible, it is added.

Finally, a weather advisory notice has been issued for Ireland, which will be in force for the full weekend.

Issued at 10:00am yesterday morning, this notice will be valid from 9:03pm tonight through to 6:00pm on Monday evening.

The national meteorological office warns that “very unsettled weather will occur over the Halloween weekend as a series of vigorous Atlantic weather systems pass close to Ireland”.

Spells of heavy rain will lead to surface and river flooding. [It will be] very windy/stormy at times with some severe and damaging gusts possible.

Some coastal flooding will be possible also due to the combination of low pressure, high tides and onshore winds. In addition, very high seas are anticipated.
