Dust blowing in SE-Iceland

Dry weather and strong winds are causing sediment from glacier rivers to blow in the SE of Iceland 19 and 20 November 2015. There was a recent jökulhlaup from Skaftárkatlar (material blown in the center of the images below).

Wind speed at Skarðsfjöruviti shows that the wind speed, gusts, exceeded 10 m/s around noon on the 19 November.

Below are MODIS and Landsat images from around 13:50 on 19 November.
