The storm has caused extensive and widespread damage to the electricity network, with power outages nationwide affecting 560,000 homes, farms and businesses.
ESB says it expects significant further outages as Storm Eowyn moves across the country.
Police in Northern Ireland have declared a major incident and said they expect the strongest winds in the region since the Boxing Day storm in 1998 which caused widespread disruption.
Speaking to media in Belfast on Thursday afternoon First Minister Michelle O’Neill and deputy First Minister Emma Little-Pengelly urged people to stay at home where they can and check in on vulnerable people.
Ms O’Neill described an “evolving situation” which they are “very closely monitoring”.
“But the key message is to stay safe, to look after yourself, to look after your family and to look after your friends and check in on those people who are more vulnerable,” she said.
Ms Little-Pengelly added that experienced emergency teams are ready to respond during the expected severe weather in Northern Ireland on Friday.
“A red alert has been issued for the entire of Northern Ireland,” she said.
“This is highly unusual, this means between 7am and 2pm tomorrow there is a likelihood of widespread disruption, danger to life and damage to buildings, and our strong advice and the advice of the PSNI is to stay at home if at all possible.”
Meanwhile, the chairman of Ireland’s National Emergency Co-ordination Group, Keith Leonard, said Storm Eowyn will be one of the most severe storms Ireland has seen.
“It is going to be a damaging, dangerous and destructive weather event,” he said in Dublin on Friday.
“The forecasted winds will bring severe conditions which will constitute a risk to life and property.
“Our most important message today is that everybody needs to shelter in place for the duration of all red warnings.
“We are likely to see significant and widespread power outages, so I would encourage everyone to prepare ahead. Make sure phones, torches and laptops are fully charged.”
The coastal town of Donaghadee in Co Down was among those making preparations on Thursday night.
Some businesses placed sandbags at their doors, while others displayed signs to say they would be closed until after the red level alert expires on Friday afternoon.
