Gales leave 3,000 without power in Northern Ireland
Thousands of people left without power because of high winds may not be back on supply until Tuesday evening, Northern Ireland Electricity has said.
NIE said its engineers had worked throughout the night and 3,000 customers were still without power.
More than 70,000 homes and businesses were affected at the height of the power cuts.
The main areas affected are the north-west, Coleraine, Ballymena and some parts of mid-Ulster.
Parts of south Derry and north Antrim were particularly badly affected.
NIE communications manager Sara McClintock said crews had been brought from the Irish Republic to help with repairs.
She said the main problem had been branches hitting lines with over 500 separate faults.
Earlier, two people were slightly injured after hoardings came off a building at Lanyon Place in Belfast and hit their car.
They were taken to the Royal Victoria Hospital. Their injuries are not believed to be life-threatening.
In Coleraine a tree fell on top of a man. The ambulance service was called, but the man refused to go to hospital.
The gale force winds have also affected transport across Northern Ireland.
A tree hit a train travelling from Belfast. It was struck just before it reached Cultra station on the way to Bangor. The Bangor to Belfast line has since reopened.
Translink said no-one was injured, but the driver of the train was "shaken".
A blanket speed restriction of 50mph was put in place across the entire rail network.
P&O Express ferries from Larne, Troon and Cairnryan, the Stenaline Belfast to Stranraer sailings and the Rathlin Island boats were all cancelled.
A spokesperson for P&O said there was a revised conventional sailing schedule between Larne and Cairnryan subject to weather.
"Passengers are advised to check in at their original reporting times to be accommodated on the next available sailing and expect long delays," they said.
The high winds have led to some roads becoming blocked because of falling trees and branches.
The police are asking motorists to reduce their speed and drive with extreme caution.
The strong winds also led to the closure of the Giant's Causeway.
City of Derry Airport experienced some disruption, with a number of flights being diverted or slightly delayed.
Belfast International and George Best Belfast City airports did not experience any delays to flights.
In Enniskillen, County Fermanagh, the fire brigade dismantled a marquee which was blown off a temporary ice rink outside the Fort Lodge Hotel.
