The southwest monsoon advanced further into parts of central Maharashtra, Vidarbha and Marathwada on Saturday. It is yet to cover Mumbai and other areas of north Konkan. KS Hosalikar, deputy director general, western region, India Meteorological Department (IMD) stated, "Conditions are favourable for the southwest monsoon to cover the north Konkan coast over the next two to three days. Two weather systems – a feeble offshore trough from south Maharashtra to Kerala, and a low-pressure area over interior Odisha, adjoining parts of Chhattisgarh and Jharkhand, will lead to enhanced rainfall activity over the west coast, including Mumbai, central Maharashtra and Vidarbha from June 23 or 24 onwards."
