Flights in and out of the UK will remain suspended until at least 07:00 BST tomorrow (April 17th).
This has been confirmed by the National Air Traffic Service (Nats) after concerns that volcanic ash stemming from an eruption in southern Iceland could damage aeroplanes’ engines and cause them to fail.
It is expected that as many as 17,000 flights have been cancelled throughout the UK and Europe today after Nats said the situation is "dynamic and subject to change".
BBC weather forecaster Matt Taylor explained that prevailing winds are expected to change slightly over the next 24 to 36 hours, which will see ash head north towards Scandinavia.
"However, later this weekend, they will return to a north-westerly direction and are more likely to bring the risk of ash back to the UK," he told BBC News.
While winds can be predicted, it is still unclear whether the volcano, which is still erupting, will continue pumping out more ash.
Nats’ restrictions have been extended as far as Plymouth and Exeter airports following the eruption in Iceland’s Eyjafjallajoekull region.
