Ash from an erupting Icelandic volcano could reach northern Scotland by Tuesday .. and parts of Britain, France and even Spain by the end of the work week , if the eruption continues at the same intensity.

The warning is based on the latest 5-day weather forecasts. Iceland's airports were closed on Sunday. With winds currently blowing the ash northwards, authorities say there's little risk of any further disruption to European or transatlantic airspace over the next 24 hours. But low-pressure weather systems are moving into Europe and Scandinavia. So there are concerns that northwesterly winds capable of dispersing ash towards the rest of Europe will pick up. Airlines have been told to brace for the possible further spread of ash later in the week.
