As the city experienced heavy rain and gusty winds for the third day on Sunday, the temperature across Mumbai fell by over four degree Celsius below normal. Weather bureau has predicted heavy to very heavy rain to continue over the Konkan coast, including Mumbai on Monday and Tuesday.
While the daytime temperature at the Colaba weather station was recorded at 26.5 degrees Celsius, 4.4 degree Celsius below normal, the readings taken at the Santacruz was 27 degrees — four degrees Celsius below normal. According to the India Meteorological Department (IMD), the mean maximum temperature for the month of September is 30.4 degrees Celsius so far.
“Very little sunshine, a cloudy sky and fast paced winds from the north-westerly direction have led to a drop in the temperatures over Mumbai. We expect the cool conditions to continue for another two days from Sunday at least,” said Shubhangi Bhute, director, IMD’s Regional Meteorological Centre, Mumbai.
The city recorded heavy rainfall between Saturday night and Sunday morning, with Colaba and Santacruz recording 54.8mm and 56.8mm rain respectively. However, after a lull during the day, the city received intermittent showers on Sunday evening. Between 8.30am to 5.30pm, Colaba and Santacruz recorded 17.4mm and 10mm rain respectively.
Under the IMD’s new classification, 15.6mm to 64.4mm of rain is considered ‘moderate’, 64.5mm to 115.5mm is ‘heavy’, 115.6mm to 204.4mm is ‘very heavy’ and more than 204.5mm is ‘extreme’.
“The low pressure area over Madhya Pradesh has now developed into an upper air circulation over parts of Madhya Pradesh, Gujarat and central Maharashtra. This phenomenon is drawing a lot of moisture along the Konkan coast, including Mumbai and heavy to very heavy rain is expected to continue,” said Bhute.
Meanwhile, nighttime temperature was closer to normal level on Sunday but high moisture level continued with Colaba and Santacruz recording 100% and 90% humidity.
