At 0600 this morning, it is clear that the UK Met Office Model has overestimated- by a considerable extent, the Southward progression of highly concentrated volcanic ash. This is shown clearly by the 0600 EU Metsat Imagery.
The CAA have admitted that high levels of concentrated volcanic ash have not covered areas of Scotland as envisaged by the model. Instead, they have stated that the ash clouds has moved ''slower than expected'' - which really is not correct.
The southernmost extent of highly concentrated volcanic ash at 0600 was near to the airport of Barra, Scotland, when the London VAAC / UK Met Office Projections indicated highly concentrated ash immediately off the North Coast of Ireland.
Safety is of course paramount at all times - however, the validity and accuracy of the UK Met model must be questioned. There has been some decline in the level of output from the Volcano, according to the latest IMO status reports, which is a welcomed development.
