However, we are not very optimistic about August because later in the month, the El Nino phenomenon is likely to develop and might affect the intensity of the Indian monsoon to some extent in the central parts and southern peninsular region of the country. Considering this, there is a possibility that even the normal August rainfall for Mumbai and adjoining areas may be affected, said Rajesh Kapadia of private weather blog Vagaries of the Weather. According to Kapadia, on Thursday the rain could be of less intensity as compared to what the city witnessed on Wednesday. Also, starting Friday and through the weekend, there will be a marked decrease in the rain intensity and frequency with on and off sunny intervals, Kapadia said. 2,015mmRainfall received till 2 pm on Wednesday 12No of complaints about tree falls
