Shivajinagar recorded 13.5mm rain, Lohegaon 15.2mm, Chinchwad 10.5mm and Lavale registered 2.5mm precipitation from 8.30am till 8.30pm on Saturday. Anupam Kashyapi, head of weather forecasting division, IMD, Pune, said Mumbai (Santacruz) reported 27.8mm rain till 5.30pm on Saturday. By 8.30pm, it went up to 115.8mm – as much as 88mm precipitation in three hours.
Kashyapi told TOI, both branches of monsoon became active on Saturday. “Monsoon progress has been observed in south Maharashtra, covering a larger expanse of the Konkan and Madhya Maharashtra areas, and in various regions of Vidarbha. These positive advancements indicate that the conditions are gradually becoming favourable for the onset of monsoon over Pune and Mumbai.”
He said, “Similar spells are likely to continue in Pune during the next four-five days. Weather forecasts and warnings for the rest of the country have been issued due to the strengthening of the southwest monsoon flow over the Indian subcontinent. Some factors behind this strengthening include a cyclonic circulation currently situated over the northwest Bay of Bengal and the adjacent Odisha-West Bengal coasts, extending up to the middle tropospheric levels. This weather system is expected to lead to the formation of a low-pressure area very soon. The cyclonic circulation in the mid-tropospheric levels over the northeast Arabian Sea and the adjoining Gujarat coast continues to persist and has intensified since Friday.”
Kashyapi said for the first time this season, Pune witnessed overcast skies on Saturday. Heavy rainfall is expected at isolated places in ghat areas of Pune, Satara and Nashik, among others, till June 28. Heavy rainfall at isolated places has been forecast for Mumbai, Palghar, Thane and Sindhudurg, among others in Konkan, till that period.
The city is likely to record light to moderate rainfall till June 26, followed by moderate rainfall till June 30. A yellow alert has been issued for adjacent ghat areas of the city.
Weather expert Vineet Kumar Singh said Mulshi got its first good rain on Saturday. “Heavy to very heavy rain is expected in Mulshi, Tamhini, Khandala Matheran from June 26 to July 1,” he said.
On Saturday, the southwest monsoon advanced into some more parts of central Arabian Sea and Maharashtra, rest of Karnataka, Telangana and Chhattisgarh, some parts of east Madhya Pradesh, Uttar Pradesh, and most parts of Uttarakhand and Himachal Pradesh.
