Rajesh Sir, when do you expect the SWM to withdraw completely from North India? According to various models, rains are in store for East U.P. and neighbourhood on the 10th, 11th, 12th and 13th of October. Is this forecast valid? What do think is in store for NW India?

sset said...

Vagaries forecast exact target - indeed it rained hard with lightening over Mumbai! No other models made this unusual time forecast!
Any idea about NEM onset - TN / SAP eager wait continues....

Cumulus arjun said...

Thunderstorms were predicted today in Mumbai but its clear and very hot. Why so??

Aks said...

Prediction is for Rain & thundershowers... that started yesterday night... Doesn't mean it will rain throughout the day!!!

Khan Gazanfar said...

When the ranins will end

Unknown said...

Yes Arjun...storms occur only in afternoon or evening/night... And not usually in the morning...its hot and sunny in Nagothane too ..

Rajesh Kumar said...

Bangalore heavy rainfall continues, today also, very bright Sunshine, it may pour today also. Bengaluru already crossed annual rainfall, NEM season is still there. 2017 may be highest rainfall year for sure. Is trend changing? Bengaluru always crossing annual rainfall data.

Rajesh Kumar said...

According to models, Rain may subside by Diwali.

sset said...

Navi Mumbai torrential rains with thunder storms = monsoon withdrawl halted?? MAHA/GUJ sweet spot?

Cumulus arjun said...

Raining here moderately since last 1.5 hours.

Saurabh said...

Not just Bangalore, here in Hyderabad too the rain gods have been very kind but they need to relent now as the rainfall is surplus and the city infrastructure is crumbling.

sset said...

Why did NEM failed 2016 - chronic drought for SE India...

Taken from net..
This is one of the very interesting questions I would also like to know about. As per IMD, the Monsoon mission coupled model forecast of 2016 suggests weak La Nina conditions over equatorial east Pacific turn to cool neutral ENSO conditions during the NE monsoon season. Similarly model also suggests the current weak negative IOD conditions are likely to continue during the NE monsoon season. Which may be the possible reason for the slightly below-normal to normal (90% -100% of LPA) rainfall over Tamilnadu.

How are 2017 conditions?? - apart from this we need siberian High formation also??

Cumulus arjun said...

Good rains today evening in Mumbai.
Mumbai ap scz - 14 mm
Mumbai city Colaba - 51 mm

Abhijit Modak said...

@ Rajesh Kumar. Yes Bangalore is inching towards highest annual rainfall ever after 2005 and some one chants continuously about it's desertification process. Lol. big blow to his repetitive theory

Vinod Desai said...

Today during the thundershower we felt as if lightning striked somewhere very close in malad. I have never heard such a loud sound till date.

Neeraj said...

It must be one of the hottest 'first week of October' here. I wonder what might be the cause and if the trend would continue into the winter. Any expert opinion ? A short write-up would be nice.

Saurabh said...

@Neeraj
That is true not just for Kathmandu but the entire region.

@Rajesh is the best person to answer that.

Models indicate the trend will change within a week. There will be a spell of rain and then the weather will be more October like.

Saurabh said...

@Abhijit
Theories built on pure fiction cannot be demolished by data and numbers.
There is talk about the previous NEM being a failure while conveniently ignoring that the one before that gave a huge surplus and caused a lot of flooding and suffering. That's what is vagaries of the weather is and that is how it has always been.

A variant of a famous quote is apt here.
His mind is made up, don't confuse him with facts.

Rajesh Kumar said...

@Saurabh Dwivedi : Rain is not only reason behind infrastructure problem. These are other significant factors pressurising existing weak infrastructure. Varuna (Rain god) just show mirror.

Rajesh Kumar said...

Meanwhile, Bangalore got 48 mm rain yesterday , and KRS is at 28.44 TMC compared to 9.44 TMC last year.. Big Relief.. Hope KRS will cross 34-35 TMC in coming days

Saurabh said...

Agreed Rakesh.

Here is what i posted last month as a comment on this site.

Regarding Water Shortage.
But there is water shortage, water tables are going down so surely there is desertification going on. The short answer is no. There is no connection between the two.

We are over populated, we don't manage our water resources well, we are using more water than nature can replenish so water tables are going down. We grow paddy in Punjab. We grow sugar cane in arid regions. If we continue like this we will face a water crisis but lets not blame climate for that without any evidence.

Coming back to the broader point. We design cities for what they are likely to experience. This is true for everything be it earth quake proofing or rain or snow. If Delhi receives Mumbai kind of rains for one season there will be no Delhi left.
Yes it is another matter that many of our cities are not even designed for what they experience regularly.
