Article on Marathwada to be Printed in Lokmat Times of Monday 3rd August..See Mumbai Page

Rajasthan Drenched by Heavy rains last week from System..see daily rainfall of last week of July in Vagaries North...and Goa Update in Vagaries Goa


July 2015  has turned out to be the 3rd driest July on record for Mumbai Santa Cruz...

This July (2015) saw 360 mms of rain, 286 mms in 1986 and the previous lowest was in 2002 at 103 mms.
Mumbai Colaba measured only 281 mms in July 2015. Though it is not a record...Lowest was a meagre 103 mms in 2002

Marathwada too is suffering from extreme scarcity...Aurangabad has seen only 14 mms this July. But this is not far, or negligible from the record low which was 11 mms in 1971.

Parbhani measured only 21 mms this year, but this not far, the lowest driest July on record was 15 mms in 1971.

Maharashtra Monsoon: 1st June - 31st July 2015

Tabulation by Vagarian Puneet 



Thursday, July 30, 2015

Friday 30th July Post (Night)...We have crossed 9.00,000 Hits .Thanks to All Vagarians 

BB-3, now a depression at 992 mb, is positioned in SE Bangladesh. Likely to track W/NW and weaken. Should weaken to 1000 mb by Sunday. 


An new embedded Low in the axis is likely to form in Central India by around 3rd/4th August.


As the erstwhile system in Rajasthan merges with the Monsoon axis, the Western end of the axis rapidly moves Northwards. Due to BB-3, the slope Eastwards of the axis is steep, sloping SE.


Friday 31st and Saturday 1st August..Heavy showers are likely in Kashmir, H.P. and Uttarakhand, Western U.P. and in Western Nepal. 

Rains increasing in both Punjabs on 1st August and continue on Sunday 2nd. 
(Gujrat in Pak Punjab gets increasing precipitation from Saturday. Saturday and Sunday showers will measure around 20 mms per day).

Heavy showers in Chattisgarh. Jharkhand and West Bengal.


Rainfall increasing (due to sectoral strengthening of the off shore trough) in South Konkan and Goa and Coastal Karnataka from Friday and effective thru till Monday.


Mumbai City: Friday and Saturday will see occasional showers, almost at regular intervals, and maybe accompanied with thunder. Friday may see around 25 mms and Saturday 20-25 mms. Sunday will see some sunny spells, with lesser frequency of showers, maybe around 15 mms.

Pune: Light drizzles in some areas, otherwise partly cloudy. 

Southern Punjab Region (Malout) will see a chance of rain on Friday, maybe around the region. Saturday will see more showers, with thunder, around 15 mms in the area. Sunday will be cloudy like Saturday with showers increasing to round 25-30 mms.


Kolkata: Having seen BB-3 weaken, and spread out its rain bands, the rain estimate for Kolkata needs revision. Showers on Friday & Saturday would average around 40-50 mms accumulated for the 2 days, and decreasing on Sunday.


Delhi NCR: Starting Friday, rains would be increasing on Saturday and more on Sunday. Chance of thunder showers on Saturday evening and Sunday, with cloudy skies and regular showers in the NCR.


Nagpur sees welcome rains starting from Sunday. Regular showers, some heavy can commence on Sunday and lead to heavy rains (40-50 mms) on Monday.

While Bangalore sees good chances of a thunder shower on Friday, Saturday, Hyderabad sees not much of rains this weekend.

North Konkan towns (Pen, Roha etc) will get passing showers amounting to 20-25 mms per day on Friday and Saturday, with rain intensity decreasing on Sunday.


Sudden Spurt of Unusual rains in Gujarat ..Bhuj and Ahmedabad Diagrams...See Current weather Page


See BB-3 making Landfall in Post Below..
Posted Thursday Evening:
"Cyclone Komen" has crossed the Southern Coast of Bangladesh Thursday late afternoon.

Moving North currently, it has weakened  


will track N/NW  soon as it encounters the STR.

Kolkata has received 14 mms till 5.30 pm IST .
---------------------------------------------------------------------------------Posted Thursday Noon:
IMD has announced BB-3 as a cyclone, due to "Intense low pressure system represented on a synoptic chart by more than four closed isobars at  2 hPa interval."
The cyclone Komen (BB-3), now formed lies 95 kms South West of Chittagong (Bangladesh), and around 300 kms East-South East from Kolkata.

And the Monsoon winds have helped in the formation of strong South quadrant convection and strong winds in the southern quadrant.Estimated core winds at 40 knts (International reading) and estimated core pressure at 989/990 mb.
 

Landfall would be on target, by Thursday (Today) afternoon at the Bangladesh Southern Coast. Heavy rains along Bangladesh and W.Bengal coast as well as Odisha coast, with winds around 40-50 kmph.
 

The initial track is North (briefly) and then track would then be W.NW , and weakening would start as explained last night.

Wednesday, July 29, 2015

Posted Wednesday Night:

BB-3 a deep depression, lay almost in the same position , South off the coast of Bangladesh. Estimated core winds are 35 knts, and estimated core pressure at 990 mb. Very strong convective bands seen in Souther Quadrant.

Initially now, BB-3 will move North, into Bangladesh. Subsequently, it will move NW, due to interaction with Sub Tropical Ridge. This will start pushing in (comparatively) dry air around the system, and due to land interface, BB-3 will weaken gradually over West Bengal.

Expecting increasing rains in Gangetic West Bengal and Odisha. 

Kolkata will get frequent showers, some prolonged and heavy with gusty winds from Thursday thru Saturday.
Would expect accumulated rainfall amounting to 130-150 mms Thursday -Saturday.

Bhubaneshwar too would get frequent intensity rains, amounting to 80-100 mms from Thursday night thru Saturday.

Last 3 days rain totals after the downpour in Gujarat (compiled by Gaurav Raninga).
