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.
The RNLI said “sea conditions at the time were very difficult and the lifeboat crews faced four metre swells, driving rain and force eight winds out at sea.”
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. A firefighter broke a rear window of the car and brought the driver out on to the roof. They walked over a ladder to safety shortly before the car was submerged in the river.
Road safety authorities North and South advised motorists not to attempt to drive through flooded roads or fords, and not to travel in heavy rain unless absolutely necessary.
