Volcanic ash may affect more flights

Donegal Airport could once again be affected by volcanic ash tomorrow according the the Irish Aviation Authority.
In a bulletin tonight, the IAA says Donegal, Sligo and Ireland West (Knock) airports will be open until 7am .
All other Irish airports will be open until at least 1pm tomorrow.
The IAA said that due to the prevailing weather conditions, and sustained low-level volcanic activity over the past number of days, the volcanic ash cloud is drifting towards Ireland from the North Atlantic.
Observation flights are planned for tomorrow to check on the level of ash concentrate.
A further update will be issued at 9.30am tomorrow.
