While the southwest monsoon bid farewell to Maharashtra on October 10, the city and a few other parts of the state are still witnessing rainfall. Speaking to mid-day, Sushma Nair, a scientist at India Meteorological Department’s (IMD) Regional Meteorological Centre (RMC) in Mumbai, stated that rainfall would vanish completely from the city only after mid-November. “However, we will see a reduction in rainfall from November 8 or 9, and then the dry season will slowly begin. Once the sea surface temperature cools down completely, there will automatically be a start to the dry season, which is expected to begin latest by mid-November,” she added.
Why has the city been experiencing extreme heat during the day and decent rainfall during evenings? Explaining the current situation, the scientist further mentioned that this is a result of low-pressure density that has formed and stayed throughout the Arabian Sea for almost 10 days in the second half of October. “There is always a post-monsoon season after October, which is highly favourable for cyclones and cyclonic activities.
