On 5 July 2010, Meteosat-9 observed a well organised mesoscale convective system over the central Sahel, particularly noticeable is the associated huge dust cloud.

The dust undercuts the leading edge of the mesoscale convective system (MCS) as a dust-wall (see lower image) associated with the passage of the gust front at Niamey (marked by a yellow dot).
Note that the leading dust wall over Niamey is not seen on the satellite image because of the higher-level clouds overlying the dust layer. Looking at the hourly animation (29 June 21:00 UTC–8 July 07:00 UTC), another big dust squall can be seen on 2–3 July over Niger and Mali.
