25th Night Post

Not predicted by any model, the defiant Cyclone "Gulab" has formed in the Bay. 

West ward movement of Gulab, and on crossing Odisha/North AP coast on 26th, very heavy rains expected on crossing. 


TPW shows Cyclone will weaken  and will move into Chhattisgarh as a Depression, again bringing heavy rains. 

Moving West into M. P, Gujarat and interior Maharashtra, it will pull moisture and precipitation into these States by Monday 27th & Tuesday 28th.

Gujarat will also benefit with increase in the rains. 

Good rainfall in Maharashtra on 27 & 28. Konkan including Mumbai can expect increase in the rains early next week. 

Fresh report tomorrow.

Posted 24th Night. 

Just yesterday we discussed the forming of BB 13 in the Bay. 

Unpredictable Favourable conditions like 80-100 Kj/cm² TCHP, wind shears, and MJO, has catapulted the system into the Bay as a Depression, on 24th evening. 40-50 kmph estimated winds. 

Will strengthen further and seeing good conditions, BB 13 will soon be Deep Depression by 25th morning. ( 50-60 kmph estimated winds) 

Due to the prevailing Sub Tropical Ridge at 20.5N  in the bay, and the Easterly winds South of it,

the System will track West or W/SW towards Odisha/North AP. 

Now, will it become a rare September Cyclone ( Gulab) in the bay? 

It at all, this will be the first cyclone after 2005 to hit AP coast in September month. And only the second cyclone in satellite era (1980 onwards). 

Another update tomorrow noon. 

24th/25th/26th September Weekend: 


Partly cloudy with sunny intervals. An occasional passing shower in different parts of Mumbai. Rainfall to increase on Sunday night. Monday 27th will get more rans. Temperature range between 32c and 25c. Real Feel 37c.

Monsoon not over. Water Storage in Mumbai lakes is 99-100%.

Pune: Partly cloudy and slightly warmer on the weekend. Few passing light showers in different parts of Pune. Temperature range between 28c and 21c. Real feel 32c.

Good rainfall increase expected in Gujarat State from Sunday 26th. Starting fron North Gujarat Region and subsequently into Saurashtra and Kutch.

Monsoon still active in Karachi (Sindh). 40 mms of rain on Thursday.

 23rd September:

Satisfactory position. Video sent by farmer ( Sonne Shyam) from Phulambari Taluka, Aurangabad, Marathwada. 

After two low pressure systems from the bay, BB 11 & BB 12 another coming  BB 13, to Odisha around 25th.

Will move across central india and northern Maharashtra next week. 

Monsoon withdrawal from West Rajasthan delayed by about 10 - 15 days, around first week of October. Maharashtra monsoon rains till at least 10-13th October.

बंगालच्या उपसागरात निर्माण झालेले २ कमी दाबाचे क्षेत्र ओदिशा किनारपट्टीवर धडकले, मात्र आता पुन्हा एक कमी दाबाचे क्षेत्र साधारण २५ सप्टेंबर रोजी ओदिशा किनारपट्टीवर धडकण्याची शक्यता आहे. त्यानंतर हे कमी दाबाचे क्षेत्र भारताच्या मध्य भागा जवळ तसेच महाराष्ट्राच्या उत्तर भागातून सरकेल. त्यामुळे अरबी समुद्रातून देखील बाष्प खेचले जाईल व महाराष्ट्रात पुन्हा एकदा पावसाचे प्रमाण वाढू शकते. 

मान्सूनचा परतीचा प्रवास पश्र्चिम राजस्थानातून साधारण १०-१५ दिवस लांबला असून साधारण ऑक्टोबरच्या पहिल्या आठवड्यात पश्र्चिम राजस्थानातून मान्सूनचा परतीचा प्रवास सुरू होण्याची शक्यता आहे. महाराष्ट्रात मात्र जवळपास १०-१३ ऑक्टोबर पर्यंत मान्सूनचा पाऊस राहण्याची शक्यता आहे.

सप्टेंबर महिन्याच्या पहिल्या २ आठवड्यात राज्यात सर्वत्र चांगला पाऊस झाला व त्यामुळे मुंबई आणि पुणे शहरांना पाणीपुरवठा करणाऱ्या धरणांमध्ये पुरेसा पाणी साठा आहे. 

पुढचे ३-४ दिवस राज्यातील अंतर्गत भागात पावसाचे प्रमाण कमी राहील, पिकांसाठी ही पावसाची विश्रांती उपयोगी ठरेल. 
कोकण आणि पश्चिम घाट परिसरात पावसाच्या हलक्या ते मध्यम सरी अपेक्षित आहेत.
साधारण सोमवार २० सप्टेंबर पासून राज्यात पावसाचे प्रमाण पुन्हा वाढण्याची शक्यता आहे, विशेषतः विदर्भ प्रदेशात. याचे कारण म्हणजे बंगालच्या उपसागरात ओदिशा/पश्र्चिम बंगालच्या किनारपट्टी जवळ आणखी एक कमी दाबाचे क्षेत्र (BB-12) १८/१९ सप्टेंबर रोजी निर्माण होण्याची शक्यता आहे व ते साधारण पश्चिम/वायव्य दिशेस सरकुन पुन्हा एकदा देशाच्या पूर्व व मध्य भागात सोमवार २० तारखेपासून पासून पावसाचे प्रमाण वाढू शकते.

Posted 14th September Night

BB 11 Deep Depression after crossing Odisha coast has tracked northwestward. The  system, is now over Chhattisgarh.

For 2 days, the deep depression left  drenched most parts of Odisha. The depression will move further northwest and weaken  in the next 24 hours.

The nearing and interaction of this system with BB 10 over Gujarat and has already enhanced rainfall over the rain deficit state.

The system as a low pressure will track in to Rajasthan and lash the border areas also with rainfall. While centred over Rajasthan, this system will give moderate rains over Haryana and Punjab

This will delay withdrawal of the monsoon from the westernmost parts of Rajasthan.

 The All India rainfall deficiency now at -5% will improve towards the end of the season.
