The National Emergency Coordination Group for Severe Weather is continuing to urge people to stay indoors until the Status Red weather alert is withdrawn tomorrow.
Here are some top tips for staying safe.
Stay warm: Temperatures today are expected to hover around zero degrees celsius but the wind chill will make it feel much colder.
Keep mobile phones charged, in case of an emergency.
Be prepared if the electricity goes. The Dublin Fire Brigade is advising people to have torches, candles and blankets on standby.
Water pipes are at risk of freezing or bursting. There is useful information on Irish Water's website.
A warning of very high tides is in place for Co Cork. High tides will occur at 6pm and at 6am on Saturday.
Dublin City Council said that because of high tides, car parks on the Strand Road in Sandymount and on the Clontarf Road near the Alfie Byrne junction, will be closed until next Monday, 5 March.
Even when the storm has passed, there will still be snow on the ground and some roads may be impassable.
The emergency services will continue to operate on Friday. The Defence Forces are also ready to deploy.
Here is a list of useful contact information for the next few days.
