Vagaries had a query in the comments column a few days back. "Why does vagaries SWM advance dates differ from IMD"? I had explained my reasons and what parameters I refer to when doing this. In fact I repeated that i follow the norms as per IMD.
Mumbai SWM was advanced by IMD on 5th June. Vagaries advanced SWM into Mumbai on 9th June. Quoting below from the "Times of India", Dated 11th June, , page 2, (Mumbai edition) what weather officials at Colaba clarified:
Quote-"So despite the torrential downpour of June 2-3, Met officials insisted any rain before June 10 was a pre-monsoon shower. It was only on June 5 that an embarrassed bureau decided to announce that the monsoon had arrived. "Thundershowers usually indicate pre-monsoon activity but we had to make the announcement, or else people would say the rains were evidently here and we were ignorant," Sharma said". -Unquote
