Entire September is monsoon month for the west coast unlike other regions where Southwest monsoon begins to retreat. But, there hasn't been any significant rain in the region for almost 5 days.
Thiruvananthapuram, in the last eight days has received only traces of rain, while Ratnagiri has received only 8 mm of rain in the last 4 days. Goa in the last 4 days has recorded 5 mm of rain. The situation in Mumbai isn't better either. In the last 4 days the city has observed 18 mm of rain, while in the last 24 hours the weather has been absolutely dry.
Mangalore is also treading on the same path with only 2.8 mm of rain recorded in the last 4 days. The west coast receives 8 to 10 mm of rainfall on a daily basis but these figures are far below, creating a deficit of 30%-70% on a daily basis. In South India rain has remained subdued for a fortnight now.
Meanwhile, rain is likely to pick up in Tamil Nadu and south coastal Andhra Pradesh from Wednesday onwards. It will then move inland towards north interior Karnataka and later travel up to Mumbai. Dry days are likely to get over and moderate rain is expected in next 48 hours. In fact some areas have received light rain on Tuesday.
