The southwest monsoon may have officially completed its four-month cycle on Friday but that did not stop it from drizzling over the city on Saturday. As a result, the temperature decreased by almost 4 degree Celsius below normal.
Between 8.30am and 5.30pm on Saturday, the Santacruz weather station, representative of the suburbs recorded 4.6mm rain while 2.4mm was recorded at Colaba. The suburbs also recorded some overnight rain as 4.2mm was recorded between 8.30am Friday and 8.30am Saturday. South Mumbai, however, recorded negligible rain in the last 24 hours.
Under the IMD’s new classification, rainfall between15.6mm and 64.4mm is considered to be ‘moderate’ while 64.5mm to 115.5mm is regarded ‘heavy’. Again, rainfall between115.6mm and 204.4mm is tagged ‘very heavy’ and more than 204.5mm considered ‘extreme’.
According to the India Meteorological Department, the southwest monsoon officially ended on September 30 after four months of activity, from June to September. This year, however, the southwest monsoon has withdrawn only till Jaisalmer, Rajasthan for the western part of the country.
Owing to thick cloud cover and light showers throughout the day, the temperature dropped considerably in the city. The suburbs recorded the day temperature at 27.8 degrees Celsius, which was 3.7 degree Celsius below normal. South Mumbai too, recorded maximum temperatures 3 degree Celsius below normal levels at 28.2 degrees Celsius.
According to weathermen, a typhoon towards the eastern part of China has led to the development of weather systems along the Bay of Bengal and Arabian Sea. That is causing rainfall in parts of the country. Weathermen predicted showers to continue over the Konkan coast, including Mumbai over the next three days from Saturday.
A typhoon is a tropical storm, either originating in the western Pacific or Indian Ocean. “The typhoon 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, Regional Meteorological Centre Mumbai, India Meteorological Department (IMD). “This, along with factors such as upper air cyclonic circulation near south Gujarat, is expected to give sporadic rain over Mumbai.”
Moisture levels were high in the city as Santacruz and Colaba recorded 92% and 95% humidity on Saturday. However, night temperatures were closer to normal levels in Mumbai.
Meanwhile, the four-month cycle of the southwest monsoon was completed with excess rain both for the city and the state (see box) till September 30.
