The challenging conditions arrived as retailers prepared for one of the busiest shopping days of the year.
Road Safety Authority spokesperson Brian Farrell said drivers need to be patient, expect delays and be on their guard.
“Watch out for vulnerable road users because it is going to be difficult driving conditions out there,” he said.
“The rain and spray from vehicles is going to reduce visibility so use the dipped headlights.”

He said drivers will have to be extra careful with Christmas shoppers braving the wet conditions.
“Our towns and cities are going to be busy and that is going to be more challenging with the wet weather that has been predicted,” he said.
“That is going to lead to a lot of surface water and some flooded roads in places.
“Really with the inclement weather and greater hours of darkness at this time of year, we need to be on the lookout for vulnerable road users.”
Dublin Fire Brigade called on drivers to leave extra space for cyclists and to plan ahead if you are Christmas shopping.
