I see the depression that left Africa just over a couple of days ago is
still heading WNW but could have problems developing due to the large
amount of sand in the circulation. On the 1800
visible(http://www.sat.dundee.ac.uk/xrit/000...1_S1_grid.jpeg)
it can be seen at roughly 15N 35W with a large swirl of sand circulating
round the north and west of the low.
