Grímsvötn volcano in Iceland began erupting on Saturday 21st May and although initially the ash cloud was expected to only affect Scandinavia, is now expected to cover Scotland and Ireland by Tuesday morning.
Icelandic airports were closed down on Sunday, although the main airport in Reykjavik is expected to reopen later today.
Some airspace over Greenland has also been closed due to fall out from the volcano.
According to the MET office, if the eruption continues in its current intensity, the ash cloud can be expected to move down through Britain, reaching France and Spain later on in the week.
“It is not likely to be anything on the scale that was produced last year when the Eyjafjallajokull volcano erupted.Pall Einarsson – Geophysicist at University of Iceland
“That was an unusual volcano, an unusual ash size distribution and unusual weather pattern, which all conspired together to make life difficult in Europe.”
Always check with your tour operator for any additional information regarding the eruption before flying.
