On the west coast, Clifden and Achill Island RNLI braved the storm to rescue a lone sailor in a vessel 10 miles west of Clare Island.

A woman had to be rescued from her car in the river Moyola, because of flooding in Draperstown, Co Derry. Fire crews from Maghera and Magherafelt said the car was almost submerged when they arrived.
