MUMBAI: The city is bracing itself for the first heavy rain of the season from June 10.
It is likely to intensify from June 12, said India Meteorological Department (IMD).
While the onset of monsoon over Mumbai is yet to be declared, IMD officials said as of Monday, the northern limit of monsoon continued to pass through Alibaug, Pune, Medak, Nalgonda, Rentachintala and Sriharikota.
While the official onset over the Maximum City is June 11, it is likely to be declared earlier this year.
IMD on Monday, while announcing a district-wise forecast for five days, issued a yellow alert for Mumbai, Thane, Palghar for June 11, indicating heavy rains at isolated places being very likely, and orange alert for Raigad, indicating heavy to very heavy rain at isolated places.
But officials said the colour coding for Mumbai is likely to be updated in the coming days.
The reason for the rain activity is formation of a low pressure area over North Bay of Bengal and its neighborhood by June 11 being likely, and strengthening of westerlies.
“An active rainfall spell is expected over Konkan, Goa and adjoining ghat areas of Madhya Maharashtra from June 10 for 4-5 days.
Widespread rainfall is expected over the region during the period, with possibility of heavy to very heavy rain at isolated places,” said IMD.
Shubhangi Bhute, scientist (IMD), said they are closely monitoring the situation.
“For now, we have announced a yellow alert, but it may be upgraded in the coming days depending on the situation,” she said.
On Monday there was significant rain in the city.
In the 24 hours between June 6-7, Colaba reported 9.4mm of rain and Santacruz 17.2mm.
