An east-west oriented shearline joining these 2 systems is embedded with another circulation over Vidarbha.

Santacruz, the official observatory of Mumbai has received 3 digits 24hr rainfall after more than 3 weeks. Last heavy spell was sometime in July, between the 10th and 15th, but evaded century rainfall. The 1st week of July was tramped repeatedly with 3 digit rainfall on 01st, 02nd, 05th, 06th and 07thJuly. The city observatory has accumulated 267mm of rainfall in August against its monthly normal of 560.8mm.
The cyclonic circulation over Gulf of Cambay is tightening and becoming strong. The winds from the Arabian Sea will be rushing over that region, depleting moisture over the Konkan coast. Accordingly, the intensity of rains will reduce today and become just intermittent and moderate tomorrow, with long breaks in between. Mumbai will remain ‘quiet’ for the subsequent 3 days, from 11thto 13th Aug. Only sporadic showers with light intensity are expected during this period.
