The typhoon in the Pacific Ocean is responsible for the downpour in Mumbai (Konkan region) and across Maharashtra over the past week, weatherman said on Monday.
A typhoon is a tropical storm, either originating in the western Pacific or Indian Ocean. The Pacific typhoon has brought life to a standstill in Philippines and Hong Kong. “The typhoon in the Pacific has created a pressure gradient in the Bay of Bengal. As a result, there is a secondary convergence (weather system) along the Konkan coast pulling moisture from the Arabian Sea,” said Shubhangi Bhute, director, India Meteorological Department (IMD). “This, along with factors such as upper air cyclonic circulation near south Gujarat, is expected to give sporadic heavy rain over Mumbai.”
Day temperatures were almost 3 degrees below normal on Monday, as heavy rain and gusty winds continued for the fourth day.
Between 8.30am and 5.30pm on Monday, the Santacruz weather station recorded 22.8mm rain and Colaba recorded 31mm. In Santacruz, it rained 110.5mm between 8.30am on Sunday and 8.30am on Monday, while Colaba recorded 38mm in the same period.
Under the India Meteorological Department’s (IMD) new classification, 15.6mm to 64.4mm of rain is ‘moderate’, 64.5mm to 115.5mm is ‘heavy’, 115.6mm to 204.4mm is ‘very heavy’.
The maximum temperature at Santacruz on Monday was 2.8 degrees below normal at 26.8 degrees Celsius, while it was 27.2 degrees Celsius at Colaba, which was 2.5 degrees below normal. Night temperatures, however, were closer to normal levels at Colaba, but two degrees above normal at Santacruz.
Moisture levels continued to be high as Santacruz and Colaba recorded 98% and 90% humidity.
On Sunday, as the monsoon season touched its half-way mark on July 31, the city recorded 75% of its annual average with two months still to go. Against the 2,258mm average rain received in the city each year, the Santacruz weather station, representative of Mumbai, recorded 1,731.3 till 8.30am on Monday, which means the city is only 527mm short of completing it’s annual average performance.
Meanwhile, water-starved areas in Marathwada got respite as Latur recorded 102mm rain over the weekend. Locations such as Parbhani and Osmanabad recorded 26.8mm and 32.5mm.
