The southwest monsoon is likely to arrive early this year, with the India Meteorological Department (IMD) forecasting its onset over parts of the south Bay of Bengal, Andaman Sea, and the Andaman and Nicobar Islands by the end of this week. This would mark an arrival five to six days ahead of its usual onset date of May 22, driven by favourable atmospheric conditions, including a low-pressure area currently active over the southwest Bay of Bengal.
