Here comes the ash again!

Airports in parts of Northern Ireland have shut down due to the latest ash cloud from Iceland’s infamous Eyjafjallajökull volcano. The main airport affected is Belfast, which will remain closed until at least 1pm local time. Ronaldsway airport on the Isle of Man is also closed.

A large cloud of ash is headed southeast from Iceland and is predicted to affect airports across the UK and the Republic of Ireland on Monday and Tuesday. If winds continue as predicted, the cloud should be out of UK airspace by Wednesday, but of course the winds could always shift back towards the UK and with the eruption showing no signs of abating, travelers could be in for another major headache.

The UK’s Met Office has produced a handy and somewhat depressing series of charts predicting the movement of the ash cloud.

Meanwhile, vulcanologist Dr. Dougal Jerram from Durham University said Eyjafjallajökull could keep erupting for several months. Vulcanologists are also worried about Eyjafjallajökull’s sister volcano Katla, which is much bigger than Eyjafjallajökull and usually erupts within a year of Eyjafjallajökull erupting.

Travelers should have figured out by this point to check ahead before going to the airport, but it bears repeating.
