As mentioned, the "pulse" from the system BB-8 (Low) has travelled West, and is embedded in an elongated trough (East-West) from South M.P. to Eastern parts of Gujarat. This is the region we see heavy rainfall occurring. Heavy rainfall and thunder showers in South MP and Eastern Gujarat regions.

Thanks Rajesh Sir for the update.
Rajesh sir please mention roha,nagothane region forecast in next update
Thanks for the update.. It was almost a dry day for Mumbai today.. Let's see, things might get interesting in the next 24 hrs.
Sir can u forecast for rajkot(Gujarat)? Bcoz all forecast models shows different amount of rain.
Mehul: I would forecast rain in Rajkot to increase from Tuesday 29th...Tuesday will see around 20-30 mms...i could be wrong.
Heavy rains have started in vasai ..its pouring here since 10 mins .quiet windy with mild thunder .
There is some lightning in mumbai sky right now.
Sir no comment for us :(
Thundering in santacruz but no rain.
Thanks sir.. Hope for the best... Farmer needs one more good spell.
Rajesg sir,its raining as per your forecast...,,,torrentially and disastrous .....what kind of wind speed do you expect in Nagothane tomorrow?I know that Mumbai would get more gales than interiors..
Currently it's raining in Andheri but not that heavy no wind currently we had heavy rain in afternoon now moderate rain
Weather is going to turn nasty soon over mumbai
Heavy rains have commmenced over vasai naigaon belt
What about western mp,,, indore region?
In rajkot we received around 50 mm in just few minutes. Its looks like new year celebration fireworks in sky.
Torrential rain water falls over belapur/navi mumbai.
Last few years of observation has seen excess rains over MAHA and GUJ west coast but most worrying factor is decreasing rain over Kerala/waynad and coastal Karnataka, malanad, kodagu due to which Cauvery is consistently lacking heavy spells. In fact in KER we have not seen even a single spell (> 200mm) since june! Some change in climate /anamoloy.

Jet streams appearance
Only hope is NE monsoon (again worry is low over orissa/NE India instead of TN/SAP)
GUJ is becoming like Hurricane Harvey!
The periodic movement of the Jet stream is often the indicator of the onset (STJ shits to the north of Himalayas in a matter of days) and subsequent withdrawal (STJ returns back to its position – south of Himalayas) of the monsoon. (I still need to google more to understand jet stream theory)
High wind in Andheri with moderate rain currently dark clouds in west and southwest direction
Heavy rain in santacruz with wind
Mumbai santacruz crosses 2000mm.
Very heavy rain in santacruz win wind.. Some area are now getting flooding
Wow 350 mm plus rains since monday till tonight possible. Any latest update on Forecast Rajesh?

Issued 29 August 2017
The latest ENSO Wrap-Up and Climate Model Summary are now available on the Bureau's website.
ENSO and Indian Ocean Dipole persist at neutral levels
The El Niño–Southern Oscillation (ENSO) remains neutral. International climate models surveyed by the Bureau suggest the tropical Pacific Ocean is likely to persist at ENSO-neutral levels until at least late 2017.
Sea surface temperatures (SSTs) have cooled over much of the central tropical Pacific during the past several weeks, yet have remained within the neutral range. Other indicators of ENSO, such as the Southern Oscillation Index (SOI), cloudiness near the Date Line and trade winds are also at neutral levels.
The Indian Ocean Dipole (IOD) is neutral, though index values have generally been above zero for the past several months. Most climate models suggest a neutral IOD is likely to continue. However, two of the six climate models surveyed suggest a positive IOD may develop during spring. Positive IOD events are typically associated with below average winter–spring rainfall, and increased spring–summer fire potential over central and southern Australia.
Next update expected on 12 September 2017
