Volcanic ash to move towards Arctic end of week: WMO
The volcanic ash cloud from Iceland is expected to change directions and head towards the Arctic when the weather changes towards the end of the week, the World Meteorological Organization said Tuesday.
"The current high pressure system with weak winds and slowly descending air in the centre of the high does not help very much to disperse the ash cloud," the UN weather agency said in a factsheet.
"This situation is expected to change towards the end of the week, when a stronger low pressure system over Iceland is predicted to develop.
"Not only will such a low change the winds and push the ash towards the Arctic, but the rains associated with this low pressure system will result in a degree of 'wash out' of ash at lower levels," it added.
