Despite cloud cover, it is possible to detect some dust blowing out to sea from the area east of Mýrdalsjökull. It is likely that this is the Eldhraun area that was flooded in jökulhlaup in Skaftá in October 2015. In the local news yesterday there was a story about a lot of dust blowing there, but clouds completely obscured the view that day.
The satellite images show the dust.
