Mumbai Rains, Weather Forecast Today Live News Updates: Isolated parts of Mumbai are likely to experience heavy rainfall in the next two hours, the Indian Meteorological Department (IMD) announced on Thursday. Despite the onset of the monsoon on June 14, the city is yet to receive widespread rainfall.
The IMD has called this a “soft onset” of monsoon, one without heavy rain over the region. The southwest monsoon onset marks the beginning of the four-month – June to September – monsoon season over India, which brings over 70 per cent of the country’s annual rainfall. The onset for India is announced when certain criteria is fulfilled anytime after May 10. If at least 60 per cent of the 14 designated meteorological stations in Kerala and Lakshadweep report at least 2.5 mm of rain for two consecutive days after May 10, along with a few other conditions relating to wind and temperature, the onset of monsoon is said to have taken place.
Last year, Mumbai had witnessed its most delayed onset in the last 45 years after the southwest monsoon was declared over the city on June 25. In 2018, the onset date was June 9 and June 12 in 2017. Thrice in the last 10 years — June 9 in 2018, June 7 in 2013 and June 5 in 2011 — monsoon had arrived in Mumbai before the IMD’s then onset date of June 10.
