The British Geological Survey (BGS) have described the eruption of Grímsvötn that began over the weekend as a 'significant eruption' and the Icelandic Met Office (IMO) have reported ash continuing to be ejected from the volcano.
As the Volcanic Ash Advisory Centre for the northwest Europe region, the Met Office is receiving information about the eruption from colleagues in the IMO and BGS. We use this to provide guidance on the movement of the ash plume.
The movement of the ash plume will depend on how long the volcano continues to erupt and how weather patterns develop. The Met Office London Volcanic Ash Advisory Centre (VAAC) continues to provide forecast guidance up to 24 hours ahead to support decision-making. This guidance is provided to the Civil Aviation Authority as the lead agency, , airports and airline operators in order to support their decisions on whether aircraft can fly safely.
Ash reports today across northern Scotland confirm Met Office ash forecasts issued on Monday. The ash is predicted to clear northern parts of the UK by early Wednesday. How this affects flight routing decisions would be determined by CAA and NATS together with the individual airlines.
Latest observations include:
Met Office forecasts for the end of this week indicate mainly low levels of ash affecting parts of UK and Europe. This forecast does depend on the status of the Volcano since the wind direction and strength will remain variable. You should stay up to date with the latest advice from the Met Office. How this affects flight routing decisions would be determined by CAA and NATS together with the individual airlines.
