The city has touched a high water mark with the cumulative rainfall crossing the seasonal average of four monsoon months.
Since June 1, the city has received a total rainfall of 2,355.5 mm, according to data from the India Metereological Department (IMD). The seasonal average rainfall from June 1 to September 30 is 2,294 mm. While it has rained 2328 mm in Colaba, Santacruz has received 2383 mm of rainfall.
“The city is expected to receive about 500 mm to 700 mm more than average rainfall till September 30,” said R.V. Sharma, deputy director general, western region, IMD. “There should be no problem with the city’s water supply now.”
Sharma added that a good combination of normal monsoon features was responsible for the city's record rainfall - low-pressure areas over the Bay of Bengal, trough of the west coast and strong wind pressure areas over the west coast of the Arabian Sea.
Even the catchment areas in Thane and Nashik, home to six reservoirs that supply water to the city, are also not far from crossing the line. In Thane, the average rainfall till August 17 is 1825.5mm — the seasonal average stands at 2410.8mm. Even Nashik with a seasonal average rainfall of 539.6mm, is only a few millimetres away with rainfall recorded at 531mm.
