Saturday Night will see less rainfall with a few showers
Sunday will be less wet than what Saturday saw..but windy. Intermittent (not continuous) showers amounting to around 40-45 mms.
For Mumbai when we say 40-50 mms, it should be taken as the average of the recording stations. Mumbai being 40 kms from North-South and 20 kms East-West, we have a varied rainfall at all places. So, average is taken by Vagaries to estimate. Like for Saturday (Daytime) the average was 110 mms..
