Position as on Wednesday Morning:
BB-3
has been classified as a deep depression, seeing the pressure deficient and estimated 3 minute winds.BB-3, stationary as mentioned, is now having estimated core pressure of 994 mb and estimated core winds of 30 knts. Positioned at 21N and 90.5E.Though International model has informed of formation of Tropical Cyclone, there is no clear cyclonic structure seen. Thick convective cloud bands are visible in South, South West and South East Quadrants (due to warm moist air from Bay SST of 31c).


 Mumbai received 32 mms at Scruz and 21 mms at Colaba in last 24 hrs ended Wednesday morning.

Badlapur, Dadar and Borivali are private readings from Abhijit, Salil and Tejas.

 ---------------------------------------------------------------------------
Mumbai received 28 mms (Scruz ) and 23 mms (Colaba) on Monday and 27 mms (Scruz)  and 19 mms (Colaba) on Tuesday.Averaging around the 20-25 mms estimated. 
Wednesday and Thursday will be similar, partly sunny and with some passing showers, may bring around 20-25 mms  per day.

As on Tuesday Night, The depression in Rajasthan was at the International Border, near SE Rajasthan and at 995 mb strength. The isobar bands were spiralled closely, and hence created very strong gusty winds in South Rajasthan, Gujarat and North Konkan.
System will weaken in the next 12-18 hrs from this posting, and a decrease in rains in Rajasthan, Saurashtra and Gujarat from Wednesday. Rains decreasing considerably in Sindh. (As mentioned earlier).

The Bay System, BB-3, remains stationary, and shows clear cut bands in the South as it strengthens. As expected, it will start its track from Thursday30th. After an impatient wait, I do not see much scope from BB-3.

Rajesh Sir.
It seems BB3 will bring rains to same area that got recent heavy rains. West MP, Raj, Kutch regions. No rains again in Telangana, NI Karnataka, Marathwada. When these areas will get rains ?

Dams too in this area not filling up in this season due to missing heavy rains from westhern ghats.

Gujarati paper mumbai samachar reports lake areas in Mumbai getting good rainfall and has accumulated storage of 46% total capacity. Today,s edition last page 12.

Sir,Not seen much scope from BB-3 means?

Rajesh said...

Dattaraj: BB-3 actually may not be very useful to India. Thats what i mean when i write "not much scope" (Gaurav: your query). But, as BB-3 moves North, in a few days, it will weaken.
I estimate another embedded Low in the axis somewhere in Central India. I do not commit now, as it will depend on axis position and BB-3 .

Here is the latest storage data from the WRD website in Mcum

Bhatsa 521/925
Vaitarna - 164/331
Modak Sagar - 111/129
Tansa - 80/145
Tulsi - 7/8
Vihar - 10/28
Middle Vaitarna - 174/195

Bhatsa and Vaitarna are also used for irrigation but I am not sure of the allocation

I read the following on http://www.accuweather.com/en/hurricane/indian. So, for you information, BB-3 is being classified as a tropical cyclone now, not a deep depression. "Tropical Cyclone 02B Forms in the Northern Bay of Bengal
7/29/2015 2:00:00 AM
As of Wednesday morning, EDT, Tropical Cyclone 02B is located approximately 85 miles south-southwest of Chittagong, Bangladesh. Tropical Cyclone 02B is moving north-northeastward at 3 mph. Maximum sustained winds are 40 mph with gusts to 50 mph.
Tropical Cyclone 02B is forecast to move northward and slightly strengthen over the next 24 hours making landfall in southeastern Bangladesh on Thursday before turning westward. This system is expected to bring flooding rain to southern Bangladesh Thursday and then northeastern India Friday into Saturday.
By AccuWeather.com Meteorologist John Schneider"

Still no good rain in almost karachi. Total rains till date 40mm. Only gulshan e hadid area which is edge of karachi got good rains.

sset said...

My guess is tropical cyclone rain quantum cannot match with GUJ / RAJ cyclonic circulations... figures ranged from 700 mm - 200 mm widespread and span multiple days!!!! Wondering why this is not present in BBC weather.

Rawat said...

Majid: Yes, I also mentioned "some International odel" has said Cyclone.
Muhammad Faisal: This was estimated for Karchi in vagaries: " Frequent rains on Monday should measure around 20 mms (avg), and again another 12-15 mms on Tuesday."
