The Irish Aviation Authority has taken the decision to close Dublin airport from 7 p.m. local time (2 p.m. EST) until 9 a.m. (4 a.m. EST) local time Monday as the volcanic ash cloud emanating from Iceland returns over Irish airspace.
"The volcano's activity and the latest weather forecasts indicate an increased quantity of ash over Irish airspace,” said the IAA in a statement.
Donegal, Galway, Knock and Sligo airports are also closed as the ash cloud wreaks further havoc on travelers.
Airports in the South are least affected, with Shannon, Cork and Kerry airports all currently open.
All passengers are advised to check with their airline carriers for further updates.
