The coastal regions of Maharashtra, including Mumbai and Madhya Maharashtra, are expected to experience heavy to very heavy rainfall over the next 48 hours. The IMD attributed this weather pattern to synoptic conditions in the Bay of Bengal and the Kutch region of Gujarat.
By Press Trust Of India : The coastal region, including Mumbai and Madhya Maharashtra, is likely to receive heavy to very heavy rainfall in the next 48 hours, an IMD official said on Sunday.
The synoptic situations such as a low-pressure area formed in the Bay of Bengal, cyclonic circulation over the Kutch region of Gujarat and an active trough spread over Maharashtra to coastal Karnataka would bring heavy to very heavy rainfall in the next 48 hours over Konkan including Mumbai and Madhya Maharashtra, the official said.
After a long gap, the southwest monsoon has been speedily progressing and covering more and more areas, the official added.
Mumbai and its suburbs received heavy rains in the last 24 hours, resulting in water-logging at various places and affecting vehicular movement on some roads.
In a rare event, the monsoon on Sunday covered both Delhi and Mumbai together.
The Colaba observatory here, representative of the island city, recorded 86 mm of rainfall in the 24 hours ending at 8.30 am on Sunday while the Santa Cruz weather station, representative of suburbs, registered 176.1 mm of rainfall in the same period, the India Meteorological Department (IMD) said.
The India Meteorological Department (IMD) has issued an ‘orange’ alert for Mumbai, cautioning citizens about the possibility of heavy rainfall exceeding 115.5mm in a span of 24 hours on Tuesday and Wednesday.
Orange alert has been issued for the districts of Palghar, Thane, Mumbai, Raigad and Ratnagiri by the met department.
Over the past 24 hours until Monday morning, Mumbai received an additional 47mm of rain following the 176mm recorded in the previous 24 hours. This significant rainfall has helped reduce the monthly rainfall deficit, which was at 95% on June 21. However, as of Monday morning, the deficit stood at 42%, as per IMD data.
According to Sushma Nair, a scientist at IMD Mumbai, the heavy rainfall in Mumbai can be attributed to three synoptic situations. Firstly, there is a low-pressure system in Odisha that is projected to move towards Madhya Pradesh.
 Additionally, there is a strong offshore trough. Finally, there are cyclonic circulations in the northeast Arabian Sea and the adjoining Gujarat coast. These synoptic situations are causing the westerlies to intensify, creating favourable conditions for the monsoon. Nair shared this information with The Indian Express on Monday.
