Whole Konkan coast of Maharashtra & Goa including Mumbai seeing one of weak monsoon since Aug. No typical revival was seen after third week of July till now due to absence of off-shore trough formation or vortex formation as all systems from Bay, either fizzled over MP or moved N/NE over Delhi/UP region and also dry winds were prominent on mid-level in same period! So no revival was seen in Aug-Sep. Even current BB-11 has moved north, which is causing flooding in HP/PB area! And Mumbai/west coast belt remain eluded!
As Vagarian Rohit has shared interesting data of Mumbai in 100 days of Monsoon 2018 on 8th Sep 2018 post, so from it taken this Sep Mumbai rainfall data.
Lowest rainfall Sep at Mumbai SCZ during past 60 years are as follow:
In Yr.1987, saw driest September with mere 35 mms!!
Yr.1986 saw 39 mms
Yr.1991 saw 59 mms
Yr.2000 saw 79 mms
Yr.1968 saw 88 mms
Current year 2018, September has recorded 62.5 mms till today in SCZ, so is not driest month but may be joining lowest Sep rainfall list. Till today sitting on 4th driest but still 5 days in hand so may be not come under top 5 driest Sep as still some TS chances persist which may be of hit & miss nature as always so if gets 1 or 2 hit TS spells in SCZ observatory area then may cross triple digit mark total for Sep month so let’s hope for the best!
Driest September for Colaba was in 1896 with just 41.1 mms recorded in whole month period! Current year 2018, September has recorded mere 23.5 mms till today in Colaba, hope it doesn't turn out to be driest Sep!!
Driest September for Dahanu was in 1952 with just 25.4 mms recorded in whole month period! Current year 2018, September has recorded mere 20.8 mms till today in Dahanu, hope it doesn't turn out to be driest Sep!!
