Around 1,000 homes and businesses are without water and approximately 29,000 more remain without power after fierce snow storms in Northern Ireland disrupted services.
Electricity poles collapsed and cables iced up in blizzard conditions while water in some remote areas dried up because powered pumps stopped working.
Northern Ireland Electricity (NIE) said it has been working "flat out" to restore supplies and has mobilised staff from the Republic of Ireland and Scotland to help with the effort.
Flying patrols were also given the all-clear to take off and patrol electricity lines in the area that cannot be reached by road.
NIE spokeswoman Sara McClintock said, "Specialist engineers will be monitoring the network from the helicopter and provide vital information on access and network damage to crews on the ground".
The wintry conditions are now expected to last well into April with this month on track to become the coldest March since 1962.
A group of students from Wolverhampton who were stranded in extreme snow in Scotland for more than three days tell their story of survival.
Cold weather can pose a real health risk to older and disabled people, but everyone can gain from preparing their homes for the cold.
