According to representatives of the UK Meteorological Office, the ash cloud arising from the eruption that started two days ago in Grímsvötn should not reach the UK before the end of the week. Anyhow, due to the constantly changing weather – more variable than during last year’s eruption – the situation is constantly evolving. Forecast graphs can be found here.
Meanwhile, in Iceland, Keflavik airport is reopening, with flights scheduled for the afternoon currently showing as on time. You can have an update on the situation at the airport from its official website.
The ash cloud reached Reykjavik city yesterday, but no warning has been issued for the population, even though graphs showed peaks in concentration this morning. In areas immediately around the volcano, in South Iceland, parents have been told not to let their children play outside because of ash in the air. The webcams at the Road Traffic Administration show clearly the ash layer on the ground.
