Bad weather is continuing to cause problems, with heavy rainfall in the south and freezing conditions reported in the midlands.
AA Roadwatch says that fresh, heavy snow is causing increasingly dangerous conditions in the west, east and southeast.
Motorists are being urged to drive with caution as a mixture of rain, slush and frost combine to make many routes dangerous.
Heavy snow and sleet in many parts slowed traffic around Dublin this evening.
Gardaí are advising motorists to avoid the M50 near the Dundrum interchange following heavy snow showers this evening.
Dublin Bus has said that some services have been curtailed as a result of the weather.
A number of routes serving the Dundrum/Sandyford areas are affected.
The vast majority of Bus Éireann services around the country are operating as normal with some delays.
Due to flooding in Cork in Kerry, a number of services are currently being diverted.
Particular caution is advised on roads in Cork, with flooding on many roads in the city, north Cork and west Cork.
A 40-strong platoon of soldiers was dispatched to Skibbereen in west Cork today after Cork County Council requested military help ahead of any expected deluge.
Very stormy and windy conditions are reported throughout Co Kerry, in addition to surface water and spot flooding.
Heavy snow has been reported in Co Wexford and the Midlands. Driving conditions are difficult in parts of Laois and Westmeath.
Heavy snowfall in Co Mayo caused two lorries to jack-knife on the N17 near Knock Airport.
Elsewhere, seven containers were lost from a cargo vessel this afternoon off the south coast.
Strong winds and 25ft high waves have been recorded off the Waterford coast and they are believed to be a factor in the vessel, the BG Dublin, losing the seven containers around 20 miles south of Tramore.
One of the containers is believed to contain the hazardous material of sodium bromate.
The coastguard has warned the public not to go within 100m of any of the containers and to contact the authorities immediately if they see them.
The vessel was on its way to Cork and is now sheltering from the high winds, which are reaching speeds of up to 50 knots.
Response Committee
Meanwhile, the head of the emergency response committee set up to deal with the adverse weather conditions has defended the group's handling of the crisis.
Responding to claims that there was a delay in setting up the National Emergency Response Co-Ordination Committee, its chair Sean Hogan said there had been a series of meetings within the Department of the Environment about the weather in advance of the first formal gathering of the national committee.
Mr Hogan was addressing an Oireachtas committee.
Fianna Fáil deputy Sean Fleming criticised the fact that the response committee was not headed up by someone in a more senior grade in the public service.
Deputy Fleming said he was appalled that a secretary general of a Government department was not appointed chair of the committee.
He said it was utterly unacceptable that someone at principal officer grade was, but he said he had nothing against Sean Hogan personally.
