The total stock in the seven lakes supplying water to Mumbai soared to 39.23 per cent

On Friday, Mumbai woke up to heavy rainfall with the city clocking in over 100 mm for the second consecutive day, leading the India Meteorological Department (IMD) – which had earlier sounded a yellow alert (moderate rain) – to annouce an orange alert (heavy rain) in the city and neighbouring Thane. The heavy showers are here to stay during the weekend with the IMD issuing a yellow warning for Saturday and Sunday.
With heavy showers battering the city since the first week of July, the Santacruz station – which had crossed its monthly average rain quota on July 14 – surpassed the 1,000 mm rainfall mark on Friday morning.
Data furnished by the IMD showed that between Thursday and Friday morning, the Colaba coastal observatory received 115 mm rain while the Santacruz station received 93 mm during the same period. Of this, the stations had received 79 mm rain and 41 mm, respectively, by Thursday evening.
Owing to heavy showers in the morning, the IMD sounded an orange for the city on Friday and Saturday, but later downgraded the alert to a yellow alert for Saturday. In its latest forecast, the IMD has indicated that Mumbai will receive heavy rain in isolated pockets on Saturday and Sunday, following which no alerts have been issued.
It was in the early hours of Thursday that the intensity of rain had gathered pace in the city, which had been witnessing only light spells of rain in the past few days.
The showers continued unabated throughout Friday, with the Colaba station receiving 66 mm rainfall between 8.30 am and 5.30 pm.
According to weather scientists, Mumbai has been receiving a good bounty of showers owing to the presence of a fully developed Low Pressure Area (LPA) in the Bay of Bengal.
Since the onset of the monsoon, the Santacruz observatory has recorded 1,407 mm rain so far, of which the city had received 347 mm rainfall in June. The Colaba station has received more rain, recording 1,418 mm rainfall since the onset of the monsoon.
Meanwhile, according to the civic data, the total stock in the seven lakes supplying water to the city soared to 39.23 per cent, which accounts for 5.67 lakh million litre, on Friday. In 2023, on the same date, the lake levels had remained at nearly 37 per cent while in 2023, the water stock soared to 87 per cent of the total capacity of the lakes, which is 14.47 lakh million litre.
