In 24 hours, Mumbai receives heaviest rainfall in a decade, says IMD

  • As of Tuesday at 8:30 am, Mumbai Santa Cruz weather station had recorded 375 mm rainfall in the last 24 hours, while 137.8 mm was recorded for Mumbai Colabaa station
  • As per the latest forecast, rains are likely to be light to moderate Wednesday onwards

New Delhi: The India Meteorological Department (IMD) said Mumbai, in the last 24 hours, has received the heaviest downpour in a decade. Heavy rains have brought the city to a halt, hitting rail, road and air traffic.

According to the weather department, a low pressure area, formed over the north-west Bay of Bengal on 30 June, has contributed to the heavy rains.

“The system has become more marked, because of which strong westerlies (winds blowing towards west) are hitting the Western Ghats and causing heavy rainfall. The stronger the moisture-laden winds, the deeper would be the clouds and more would be the rainfall," said Dr D S Pai, senior scientist, IMD Pune.

According to officials, there is also formation of a trough near the west coast which is adding to the precipitation. A trough is a region of low atmospheric pressure associated with cloudy conditions and rains.

As of Tuesday at 8:30 am, Mumbai Santa Cruz weather station had recorded 375 mm rainfall in the last 24 hours, while 137.8 mm was recorded for Mumbai Colabaa station.

The city faced one of its worst deluges during the monsoon season in July 2005 that killed hundreds of people. This year, though the monsoon onset was delayed, rainfall has been extreme.

As per the latest forecast, rains are likely to be light to moderate Wednesday onwards, except for some regions, which could still receive isolated heavy showers. In response to changing weather conditions, IMD has issued a red warning for heavy rainfall over Madhya Pradesh, Chhattisgarh and Vidarbha in the next three days, as the low pressure system is most likely to move northwards.

The low pressure system is also expected to give a necessary push to the western arm of the southwest monsoon to advance into north-western region, which is under heat wave conditions with average maximum temperatures reaching up to 45°C. The northern limit of the southwest monsoon continues to pass through Dwarka and Ahmedabad in Gujarat, Bhopal (Madhya Pradesh), Sultanpur, and Lakhimpur Kheri (Uttar Pradesh) and Mukteshwar (Uttrakhand).

The department has pinned its hopes on the system to help the monsoon advance into West Uttar Pradesh and Himachal Pradesh from July 3-5. Meanwhile, enhanced rainfall activity would continue over Madhya Maharashtra, Marathwada, Gujarat region, East Rajasthan and West Madhya Pradesh Wednesday onwards, said IMD.
