On 16th July, Skymet predicted that Mumbai stands a fairly good chance of recording all-time highest rainfall in the month of July. The city has already recorded 1010 mm of rain in this month and good showers are likely during next 48 hours.
After receiving 46 mm of rain on the 17th, rain reduced and the city recorded just 10 mm on 18th and 3 mm on Saturday. Mumbai will continue to receive rain throughout the month, but with varying intensity.
As more rain is in the offing, it will not be surprising if Mumbai touches the all-time highest rainfall of 1455.5, recorded in the year 1965. The city could also record the second highest rain of 1454.5 mm, recorded in July, 2005.
This year the month of June has been the driest in over a decade in Mumbai, leaving the city with a rain deficit of over 65%. The total of 87 mm of rain was the third lowest monthly total in last 63 years. However, July began on a very good note with heavy spells of more than 100 mm on four occasions and 207 mm of rain recorded on 3rd July alone. Barring one dry day on the 6th of July, rain has been continuous in Mumbai.
According to the latest weather update by Skymet Meteorology Division in India, Mumbai also stands a good chance of catching up with the huge rain deficit left behind by June.
We can thus conclude that Mumbai remains unaffected by El Nino, which affects the overall Monsoon performance in India, including onset, periodic coverage and withdrawal. In fact, this year the trend followed by Southwest Monsoon has been abnormal or probably unique. Rain actually decreased in major cities right after Southwest Monsoon ushered in.
