Despite signs that the Eyjafjallajökull volcano is calming, the European Meteorological Offices remain on full alert to monitor the atmospheric conditions. Conditions are changing with volcanic ash now being thrown up to a height of only 3 to 4 kilometres, compared to 6 to 7 kilometres earlier. The advent of a low air pressure system over Iceland in the next three days is expected to move the volcanic ash towards the Arctic, while the accompanying rains could wash down the ash at lower heights.
