There is a notable duststorm advancing southwards over western Algeria. This
afternoon's noaa19 overpass shows the extent, the line of advancing dust is
well over 1000 miles long. Thick dust is shown in yellow, thinner raised
dust in pale blue in this false colour image using spectral channel 4 minus
channel 5.

From the few SYNOPs that are available it looks as though the surface winds are
20-25 knots.
