Satellite cloud pictures of west/westnorthwest moving monsoon depressions have been examined by dividing the area 10 degree latitude/longitude around the surface position of the depressions centre, into 2.5 degree grid squares. The isopleths of mean cloudiness, coefficient of variation and preferred zones of large and low cloudiness are discussed in relation to the large scale flow pattern associated with the depressions. Broad category of cloud patterns have been identified in the satellite pictures. An attempt has been made to estimate daily rainfall in different sectors of the monsoon depression from these pictures.
