Mumbai finally witnessed the official onset of the southwest monsoon on Tuesday, nearly a fortnight later than its normal arrival date of June 11. The delayed onset brings an end to speculation over its progress, with the India Meteorological Department (IMD) confirming that the monsoon has now advanced over the financial capital and the rest of Maharashtra.

"Southwest monsoon made its onset over Mumbai on June 23," India Meteorological Department (IMD) scientist Sushma Nair said.
