Relay Race Of BOB Low Pressure – NW Bay OF Bengal Hosts Another Low

Current Weather Conditions on 25th July 2013 @ 1.00 pm.

There has been fairly widespread rainfall over Saurashtra & Gujarat during the last two days.
As had been indicated yesterday that there is a relay of Low Pressures developing over the Bay of Bengal, mostly over Northwest Bay of Bengal; a new Low Pressure area has developed over Northwest Bay of Bengal and adjoining coastal areas of West Bengal & Odisha.  The UAC extends to up to Mid-tropospheric levels, tilting southwestwards with height.

The earlier Low pressure area was located yesterday evening over West Madhya Pradesh and adjoining Southeast Rajasthan. This Low now lies over Madhya Pradesh, Rajasthan & U.P. border areas.

The axis of monsoon trough at mean sea level passes through Ganganagar, Narnaul, Center of earlier Low Pressure area, Ambikapur, Center of the fresh Low Pressure area and thence Southeastwards to East Central Bay of Bengal.

The off shore trough at mean sea level currently runs from South Gujarat coast to Lakshadweep area.

TMD Map showing Low Pressure Areas Dated 25th July 00 UTC (5.30 am. IST.)

As has been indicated a new Low Pressure or a UAC expected to develop before the end of this month.

Forecast: 25th to 28th July

Rainfall forecast for Saurashtra, Gujarat & Kutch has been given for this period yesterday and stands valid as yet. The only observation is that rainfall quantum would be light, medium & heavy in different places on different days. Now current possibility is more rain for West Coastal Saurashtra.

As per your prediction and answer of my question of 25th July , you did mentioned that “Kutch should get reain on 28th July” and really there was good rain around Rapar area(more than 100 mm) on 28th July but apart from Rapar, all the area of kutch are still waiting for good rain so what your prediction for that. At present very very light rain is continuing over Bhuj.

Dear Ashokbhai,

1) It is observed that, every time this season, Low pressure tracked towards North- North westward from Bay of Bangal and once it is reached to west MP, it goes towards rajasthan instead of Gujarat.

2) Even near by area of Rajkot get good rainfall but rajkot doesn’t. what could be the reason?.

is there any possibility that rajkot get good rainfall from this system?

Sir,

Once again the train missed the station called Rajkot !!! It rained everywhere in Saurashtra but Rajkot. I feel that Rajkot has been absolutely unlucky this year… Total quantum received can be above 300 mm but no meaningful rain… Aji dam only 5 Ft..

Dear Ashokbhai, I am found of watching this site. I am also from Rajkot but currently in Pune. I have below questions, 1) It is observed that, every time this season, Low pressure tracked towards North- North westward from Bay of Bangal and once it is reached to west MP, it goes towards rajasthan instead of Gujarat. 2) Even near by area of Rajkot get good rainfall but rajkot doesn’t. what could be the reason?. 3) Very little time seen that off-shore trough is much active and gives good rainfall to Gujarat instead waiting for UAC/Low pressure from Bengal as… Read more »

Sir, how this year going to be for Kutch. Since there has not been rain in bhuj. Even after so many weather forecast the rainfall in Kutch region is neglegible. So let me know is this going to be the same dry year as the previous one.

As per the your forecast, Saurashtra & Gujarat region got meaningful rain (light ,medium & heavy) but Kutch did not received. So is there any chances for Bhuj area ?
