Schools in status red and orange areas are being advised to stay closed on Wednesday, as Storm Barra continues to hit the country.
That initially covered schools in Donegal, Sligo, Leitrim, Cork, Kerry, Waterford, Limerick, Clare, Galway, Mayo and Wexford.
However, Met Éireann has subsequently issued a status orange warning for Dublin as well - valid from 1am to 7am on Wednesday.
It has since been confirmed that schools in the capital will remain shut tomorrow as a result of the latest warning.
Earlier, the Department of Education said schools in the impacted counties should remain shut so the damage from the storm can be assessed.
Schools in other counties can reopen, unless there are concerns around fallen wires or serious damage near the schools.
In a statement, the Department said: "If an individual school (in a yellow area) is still experiencing a particular local issue relating to the storm the Board of Management can make a decision to remain closed for tomorrow.
"All schools should keep up-to-date with the current weather warnings which are carried on all national and local news bulletins and in particular any change in the status warning for their area."
Universities and colleges in impacted counties are also being advised to stay closed tomorrow.
Storm Barra continues to bring very strong winds to parts of Ireland, with weather warnings remaining in place for many counties overnight and into tomorrow morning.
#StormBarra will continue to bring strong and damaging winds tonight and tomorrow with a continued risk of fallen trees, dangerous driving conditions and danger to life.
⚠️ #Wind and #Rain warnings in place until 18:00 Wednesday
