Met Eireann has issued a Status Orange wind warning for Storm Brian, which is expected to hit Mayo, Galway, Clare, Kerry, Cork, Waterford and Wexford on Saturday.
The second major storm in six days will bring west to southwest winds veering northwest will reach mean speeds 65-80 km/h with gusts 110-130 km/h.
There are concerns about structures that were already damaged or destabilised by Ophelia, especially in Munster and to a lesser extent in Galway, which did not experience the worst of the ex-hurricane.
The Status Orange warning was issued on Thursday 19 October at 21:00 and will be valid throughout Saturday 21 October, from 06:00 until 18:00.
Caution is advised; however it is unlikely, at least in Galway, that the storm will be as ferocious as Ophelia.
