Eumetsat has great satellite imagery covering the whole continent . Takes a little while to search through the website initially .
examples :
EUMETSAT IPPS animation - Meteosat 0 degree Visible 0.6 Central Africa
EUMETSAT IPPS animation - Meteosat 0 degree Visible 0.6 Western Africa
Those are visible images for central and west africa today
Below is the link to the west african IR image :
EUMETSAT IPPS animation - Meteosat 0 degree Infrared 3.9 Western Africa
Anyway , have a play with it , I'm sure you'll find it quite useful
