As lakhs of devotees bid adieu to Lord Ganesh through various immersion processions in the city between Thursday and Friday morning, they encountered widespread heavy rain, which is expected to continue over the weekend.
Between 8.30am on Thursday and 8.30am on Friday, the weather station at Santacruz recorded 80.6mm rain while 55.6mm was recorded at Colaba. Before showers, Mumbai was witnessing mostly dry weather conditions with a few isolated spells of rain since the beginning of the month.
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’.
Weathermen attributed the downpour owing to a low pressure area over coastal Andhra Pradesh. “The western coast has witnessed an increase in rain due to moisture incursions over the region,” said KS Hosalikar, deputy director general, western region, India Meteorological Department (IMD). “It is due to low pressure area that has formed over Telangana and adjoining areas.”
He added that heavy to very heavy rain had been predicted for Mumbai, the rest of the Konkan coast and interior Maharashtra for the next 48 hours from Friday. “The possibility of a few very heavy spells cannot be ruled out as the low pressure area is now shifting westwards towards Mumbai,” Hosalikar said and added that this weather phenomenon generally takes place as the monsoon withdrawal begins. “The southwest monsoon has begun its withdrawal process over parts of Rajasthan.”
Meanwhile, night temperatures in south Mumbai was closer to normal levels while the suburbs recorded minimum temperatures a degree Celsius below normal. Maximum temperatures, however, last recorded on Thursday were closer to normal levels.
City surpasses its annual average rainfall
As Ganeshotsav came to a close on Thursday, the city also received its complete share of monsoon rain. With half of the month still remaining for the four month monsoon cycle to be completed, the Santacruz weather station (representative of Mumbai) received 2340.2mm rain till Friday morning. The average rainfall in the city is 2,258mm every year. Meanwhile, the weather station at Colaba too, is just 23mm short of completing the average for the four monsoon months as 1901.8mm was recorded till 8.30am on Friday.
