Heavy to very heavy rainfall levels are likely to reduce to light to moderate through Wednesday.

However, as of now our warnings continue,' said KS Hosalikar, deputy director general western region, (IMD). He added that three weather factors that led to the heavy cloud formation still persists. 'A low pressure area over Bay of Bengal, cyclonic circulation over central Maharashtra and a trough (weather depression) that extends from Konkan coast to Kerala, led to the dark cloud formation over Arabian Sea that moved over onto Mumbai and parts of Konkan. While these factors are still strong, the system is shifting northwards,' he said. 'This is one of the highest rainfall levels seen during September in the city’s history.' The city recorded a drop night temperatures owing to the continuous downpour.
