The Department said: "Schools that are no longer in a Red or Orange Alert area can reopen, provided that, if there are concerns, school managers have had an opportunity to check for fallen wires and other serious damage in the vicinity of school buildings.
"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."
Most of the rest of the country remains under a status yellow warning until tomorrow evening.
