Motorists have been advised to exercise caution on the roads.
Met Éireann has issued a new Status Yellow snow and ice warning for eight counties in Ireland.
The warning was issued on Tuesday morning and is valid from 8am on Tuesday until 6pm on Wednesday evening.
It affects Dublin, Kildare, Louth, Wicklow, Westmeath, Meath, Cavan and Monaghan.
Met Éireann said accumulations of between 2cm and 5cm of snow are possible in these counties.
The Met Office has also issued a Status Yellow snow and ice warning for Antrim, Armagh and Down.
This comes into effect at 4pm on Tuesday and remains in place until 11am on Wednesday morning.
It said scattered snow showers blowing in from the Irish Sea may cause minor travel disruption due to snow and ice.
A weather advisory for all of Ireland remains in effect until 6pm on Wednesday evening, advising of very cold weather with snow and icy patches.
Motorists have also been advised to exercise caution in the coming days due to the risk of snow, ice and frost.
AA Ireland said as Met Éireann is warning of snow and ice this week, particularly along the east of the country, people who need to travel should exercise caution.
“On icy roads it can take much longer to bring your car to a stop in an emergency, so it’s important that you reduce your speed and allow extra distance between yourself and other road users," Conor Faughnan, AA Director of Consumer Affairs said.
