People living in areas where there's a status red warning this evening are being urged to stay indoors.
Chair of the National Emergency Co-Ordination Group, Sean Hogan, says everyone needs to heed the warnings.
"Snow is continuing this evening and will for some hours overnight yet.
"This is falling quite heavily in places.
"So our message remains about not undertaking travel, other than in exceptional circumstances.
"This is an on-going event and conditions are still deteriorating in many areas.
"So please: only those who need to be out and who are contributing to essential services or otherwise should be out on the roads".
Most public transport is expected to resume tomorrow morning, although significant disruption is expected.
Flights are also expected to begin arriving and departing at Dublin Airport in the morning.
Today, drivers are still being told to avoid the roads if it all possible.
