Thousands of people are without power around Ireland due to Storm Eunice.
The ESB says Cork and Kerry have been the worst-affected areas, with some 80,000 customers without power across the country.
The most affected parts of the country are in the south-west - such as Cork, Kerry and Limerick.
However there are also outages reported in more central regions such as Athlone - as well as outrages in Donegal.
Fallen trees are the main reasons for the disruption. Crews are working to repair services, where it is safe to do so.
Siobhan Wynne from the ESB earlier told Newstalk Breakfast they are expecting more outages.
"They're mainly in the south of the country, parts of Cork and Kerry have been worst affected so far.
"I'm just conscious that we are still at the early stages of this storm, so we would expect there to be further impact now as the next couple of hours unfold."
She says they hope to restore supply as soon as conditions allow.
"All of our crews are mobilising at the moment... We hope to restore power to those customers within the next few hours.
"It just depends now on how the storm develops in terms of the number of customers who may be affected over the course of the morning."
People can report downed power lines to the ESB on 1800-372-999, or check the status of an outage on powercheck.ie
'Going to quickly deteriorate'
Matthew Martin from Met Éireann earlier said overnight weather was calm, but this changed in many areas this morning.
"Whilst conditions haven't been too bad overnight, they're going to quickly deteriorate now across west Kerry and west Cork.
"We're going to see very strong, significant winds extend eastwards across the country during the morning.
"Whilst you might be waking up thinking 'It's not all too bad', things are going to deteriorate through the morning."
Winds affected Cork and Kerry between 8.00am and 9.00am - while the east coast felt the impact of those winds from 9.00am.
"There'll be a sudden increase in wind speeds around that time", he said.
And Anna Cullen from AA Roadwatch had this advice for road users.
"Temperatures will pick up, the winds will pick up - and conditions will unfortunately get worse out there.
"Our advice, basically, is to slow down. If you are in a red area, the advice really is to not travel at all.
"But if you do need to travel: slow down, allow extra stopping distance... adapt your driving to the weather conditions, so be on the look out for vulnerable road users.
"And if you haven't left already this morning, just allow an extra 15 minutes on to your normal commute."
