Updated on July 16, 2021 09:00 am: The Santacruz observatory had already recorded 96 mm rain during last 21 hours. Heavy showers have been going on over many parts of Mumbai. In fact, waterlogging has been reported in many parts of Andheri, Kurla, Chembur, Tilak Nagar and many other low lying areas.
However, it was between 5:30 am and 8:30 am that the deluge rainfall happened. The city of dreams saw a whopping 157 mm of rains in three hours taking the 24 hour rain figure to 253 mm.
Updated on July 15, 2021 09:00 am: Colaba observatory of Mumbai recorded 111mm rainfall yesterday. This is the 1st three-digit 24 hours rainfall of July 2021, and takes the total of the season, since 01st June, to 1003.8mm and an excess of 110.9mm from the normal. The other base observatory at Santacruz has missed the century mark by recording only 90mm rainfall, but it is likely to catch up today with a heavy downpour over most parts of Mumbai and suburbs. The total Mumbai rains recorded at this official observatory is 1253.8mm and way ahead of normal by 372.3mm. Actual rainfall measured at Santacruz is just short by 80mm from the total of June and July and is likely to surpass today. Mumbai will stand a chance to complete August rainfall (585mm) also in the 2nd fortnight of July.
A low-pressure area is marked over the Gulf of Cambay in the Arabian Sea and adjoining Saurashtra, South Gujarat, and North Konkan. This feature has steered the Konkan coast winds to dead westerlies and therefore ideal conditions for heavy to very heavy rainfall for Mumbai for the next 24 hours.
Mumbai will have a high tide around 3’o clock in the afternoon and early morning which may coincide with the intense rains in the night and morning hours. The downpour may also cause interruption of rail, road, and air traffic. Waterlogging and inundation of low-lying areas will trouble the commuters and impact routine activities. Mumbai may have slight breather on 16th and 17th July with only moderate rains, to pick up again from 18th July onward.
