Matthews Coaches services remain suspended.
Matthews Coaches have confirmed they will continue to keep their services off the road for another 24 hours, until at least Sunday.
'Due to the ongoing weather conditions, Matthews.ie have suspended all routes for another 24 until the end of Saturday March 3,' the company said in a statement.
Matthews.ie operates 133 services a day between the north east and Dublin but have not been on the road since Tuesday after night with a Status Red weather warning in place in the region since 5am on Wednesday morning.
The company will review the situation regarding Sunday March 4 and passengers will be kept updated through the Matthews.ie Facebook page.
Additionally, Bus Éireann - who have been off the road for three days themselves - have issued an update.
No Bus Éireann services will operate for the remainder of Friday, March 2 due to ongoing severe weather conditions and extremely challenging road conditions.
This includes all city and town services, the Expressway intercity network, and Eurolines services to the UK.
'We anticipate that we may be able to resume a level of services in some parts of the country tomorrow morning (Saturday), dependent on the local road condition,' a spokesperson said.
'It is our aim to operate some services on the Expressway inter-city network, and possibly a level of regional city and town services, in less affected areas.
'However, there will not be any kind of full service schedule tomorrow due to difficult and dangerous road conditions in many parts of the country. We apologise for the inconvenience but safety of staff and customers is paramount.'
Given weather conditions in Dundalk and across Louth, it is considered unlikely Bus Éireann services will resume over the weekend.
