From The Irish Aviation Authority:
The IAA has cleared Irish Airports to open for full operations from 1300 hrs local time today Tuesday 4th May. Dublin, Shannon, Cork, Knock, Donegal, Waterford, Kerry, Galway and Sligo may resume normal operations.
Current Information from the VAAC confirms this information. We expect operations to be normal at all Irish Airports for the rest of today.
Ireland will not fall within the predicted area of ash concentrations that exceed acceptable engine manufacturer tolerance levels.
Our decision to close earlier today was based solely on the safety risks to crews and passengers as a result of the drift south of the volcanic ash cloud caused by the north easterly winds.
The situation will be reviewed as the week goes on. Winds are forecast to continue coming from a Northerly direction for the next few days and this could lead to further problems.
There will be a further update on the IAA website at 20.00hrs tonight, Tuesday 4th May, 2010.
As you were people, but be prepared for more fun on the way….
