Cork is the eye of Storm Éowyn, with a red alert for wind in place for another three hours
Thousands are without power as strong gusts of near 120 km/h were recorded in Cork in the early hours of the morning.
Council, ESB and Uisce Eireann repair crews are all on standby as the storm has already caused significant damage across the city and county.
The advice is to stay home and off the roads during the Red Alert and to be aware that an Orange Alert for wind will be in place from 10am for most of the day.
Speaking to RedFM News, City Council's Director of Services David Joyce says anyone taking to the roads later this morning will come up against fallen trees and power lines:
"We would advise against any unnecessary travel, but if you are travelling out in the Orange alert later to be aware of any fallen trees or debris on the roads. If you do have to travel please slow down and anticipate the unexpected."
