According to India Meteorological Department (IMD), during the just concluded Post Monsoon Rainfall for 2020, that included rainfall during Oct-Dec months, India received 124.6 mm rainfall, 0.64% above the normal rainfall of 123.8 mm during the period. As per IMD[i] definition, the rainfall was thus normal.
This three-month period from Oct 1, to Dec 31 includes the North East Monsoon that mainly affects parts of South India including Tamil Nadu, Puducherry, Rayalseema, parts of Karnataka and Kerala. IMD declared on Jan 1, 2021 that the of NE Monsoon ended on Dec 31, 2020 with normal overall rainfall: TN had 6% above normal, Karnatak 13% above normal, Puducherry 32% above normal, Andhra Pradesh 33% above normal. However, Lakshadweep had 9% below normal and Kerala 26% below normal. This monsoon provides 48% of the annual rainfall of TN so it is most imp for that state.
The rainfall revived only towards the end of November, mainly due to two consecutive cyclones — Nivar and Burevi — both of which developed in the Bay of Bengal. While Cyclone Nivar crossed the coast close to Karaikal near Puducherry and brought heavy showers for the east and coastal districts of Tamil Nadu, Cyclone Burevi weakened before it reached land.

Higher Courts and NGT has been giving numerous orders and judgments, but the state is happily getting away with non implementation in most cases. How can we ensure that court orders get implemented? Why is the judiciary not concerned about non implementation of its orders? This was one of the central message of the East Zone River Sand Mining Dialogue on Nov 21, 2020 (4-6.30 pm) as part of the India Rivers Week 2020[i] theme “Is Sand Mining Killing our Rivers?” Additional Director R B Lal from Union Ministry of Environment and Forests in his presentation agreed that the sustainable sand mining guidelines have not been implemented. One would have liked to hear how we can achieve their implementation and that MoEF also values participation of people at the grass roots in sand mining governance. He did not mention the local people even once, while praising MoEF’s emphasis on technology in the sand mining guidelines.
The Dialogue was very ably moderated by Dr Malavika Chauhan of Tata Trusts and Dr Debashish Sen of People’s Science Institute (Dehra Dun). This was Fourth in a series of Zonal River Sand Mining dialogues being held after North Zone[ii], South Zone[iii] and West Zone[iv] Dialogues held earlier.

Improper operations of dams, disasters related to dams and hydro projects and breaching of embankments have been aggravating flood disasters during every monsoon. There have been several such incidents during South West Monsoon 2020, taking heavy toll on people and property which could have been avoided or impacts reduced in many cases with proper dam operations and proper maintenance of the embankments. This compilation attempts to put together all such instances when avoidable flood disasters were created by improper operation of dams and breaching of embankments in the south west monsoon 2020.

India received 957.6 mm rainfall in Just concluded South West Monsoon 2020, during the scheduled 4 month monsoon from June 1 to Sept 30, 2020. This is 8.74% above normal monsoon rainfall of 880.6 as per India Meteorological Department (IMD). This is considered ABOVE NORMAL rainfall, since rainfall is in the range 4-10% above Normal rainfall. This sounds good at national level, but the situation on ground could be very different, if we see the rainfall across the country.
It is noteworthy as per even IMD, monsoon has not yet withdrawn from most parts of the country. But IMD closes its monsoon rainfall account at 0830 hours on Sept 30, so all rainfall after that hour has to be counted in “Post Monsoon” rainfall book, even though the rainfall is very much part of monsoon as per IMD.

In the ongoing South West Monsoon, India received 44 year old high surplus rainfall of 327 mm in just concluded Aug 2020, 26.6% above normal rainfall of 258.2 mm. This helped the total June-Aug 2020 rainfall to achieve 10% surplus, with actual rainfall 780.3 mm, 69.9 mm higher than normal rainfall of 710.4 mm. In June the country received 18% above normal rainfall and in July it received 9.9% below normal rainfall, the rainfall at the end of June was just 1.1 mm above normal. Thus almost the entire surplus rainfall is thanks to the rainfall during Aug 2020. The rainfall distribution has however, been far from normal that these figures suggest, as we can see from the state wise and district wise figures below.

During the just concluded first half of the South West Monsoon 2020, India received 453.3 mm rainfall, just 1.1 mm above the normal rainfall of 452.2 mm during the period. The Surplus of 18% rainfall that India received in June 2020 has thus been wiped out by the 9.9% deficit in July rainfall. Normal rainfall in July 2020 is 285.3 mm, while actual rainfall was 257.1 mm. IMD does not provide monthly figures of rainfall for different states, sub divisions and river basins, which it should along with comparison with respect to normal rainfall and rainfall last year.
To get July 2020 rainfall, we will need to use the figures given in this article along with the figures of June 2020 rainfall (see: https://sandrp.in/2020/06/30/district-wise-rainfall-in-india-in-june-2020/). The district wise figures of June-July 2020 rainfall can be seen in this PDF file from IMD: IMD DISTRICT WISE RAINFALL FROM JUNE 1 TO JULY 31 2020.

The Supreme Court appointed Ravi Chopra committee has submitted the report on Char Dham Road. It has not said NO to the all weather road which is the slogan of Gadkari and rest of the Union Government. It has in fact, going by the Union Ministry of Road Transport’s’ circular, as late as 2018, suggested that the road be of 5.5 m width with necessary precautions. It has provided elaborate justifications and reasons why it took this decision. And yet twelve govt members of the committee, claiming in the name of religion (as per interview by one of these twelve members in media today) has insisted that the road should be of 10 m width. Not bothering that religion was not part of their mandate, not bothering what impact such a road will have on the Ganga (and the impact will be massive, we will know the full extent only if the impacts are scientifically assessed), on Himalayas (again starting from deforestation, landslides, flash floods and so on will be unbelievably huge) and on people and future generations. One only hopes the Supreme Court will see through the mindlessness of the economic fundamentalism being pushed in the name of religion and not allow the proposal to go ahead.
The Union Environment Ministry is clearly out to destroy even the Bhagirathi Eco-Sensitive Zone by sanctioning the Zonal Master Plan without due process and in complete violation of the letter and spirit of the Bhagirathi notification. This will further open the flood gates for destruction of remaining stretch of Bhagirathi, considered original Ganga stream as it flows from Gangotri. Again one hopes the judiciary will strike this down.
One wonders what is the NMCG, National Mission for Clean Ganga, whose mandate is Ganga rejuvenation, is doing amidst all this? Why is it silent?

As over 4 million people in the flood prone areas of North East go through second wave of floods and Ganga basin enters the long flood season, nation’s focus should be on one particular agency, Central Water Commission which is not only the only flood forecasting agency, but is also answerable in multiple other ways for the recurring flood disaster. But the flood forecasting of CWC[i] is grossly inadequate, inconsistent and non transparent.
To illustrate, let us look at the available information about CWC’s flood forecasting and compare it with happened in 2019 flood season. Out of 29 sites[ii] (7 level monitoring sites and 22 Lavel forecasting sites) where rivers crossed the previous Highest Flood Level as per CWC’s own hydrographs of last year, CWC has not updated HFL for at least 8 sites so far this year. In case Salavad in Jhalawar district in Rajasthan, on Kali Sindh river, in stead of updating the new HFL, CWC suddenly discovered this year that that the site had higher HFL achieved 35 years ago in 1985, though till last year, it listed 1996 HFL!

Here we present the rainfall figures from India Meteorological Department in the just concluded month of June 2020, the first month of SW Monsoon 2020. The overall rainfall at all India level in June 2020 was 196.2 mm, 18% above normal rainfall in the month at 166.9 mm. It was 33% deficit last year.
This is India’s wettest June 12 years, The Times of India reported on July 1, 2020. Agriculture Ministry Data shows that sowing is 68% higher at 31.56 m ha. The June rainfall was 202 mm in 2008, the rainfall this year is the highest since then. All four IMD regions (Northwest, Central, South, East & NE) have recorded surplus rainfall, the surplus is the highest in Central (30.5% surplus) and E-NE (15.7%) regions. North West India had the lowest surplus at 3.5%. IMD Head Mrutyunjay Mohapatra said that whole of India was covered by monsoon on June 26, 12 days ahead of the normal date of July 8.
State wise rainfall Three states had large excess rainfall (above 60% surplus rainfall), namely Bihar, Madhya Pradesh and Sikkim. Eight states/UTs (Union Territories) had excess rainfall (20-59% surplus): Assam, Meghalaya, UP, Chhattisgarh, Maharashtra, Telangana, Andhra Pradesh & Andaman and Nicobar. Nine had deficient rainfall (20-59% deficit): Lakshadweep, Mizoram, Manipur, J&K, Ladakh, Himachal Pradesh, Delhi, Dadar & Nagar Haveli. Rest of India had Normal Rainfall.

India Meteorological Department (IMD) divides a water year (June 1 to May 31) into four seasons: Monsoon: (June 1 to Sept 30), Post monsoon (Oct 1 to Dec 31), Winter (Jan 1 to Feb 28/9) and Pre Monsoon (March 1 to May 31). For rainfall during all these seasons, IMD’s hydro-meteorological website[i] provides a lot of data on daily basis, including daily district wise rainfall, state-wise, sub division wise and river wise daily rainfall maps among many other weekly, monthly and seasonal products. However, one problem with it is that none of this information is achieved. So if you missed seeing or downloading available data on any date, there is no way to look at it even next day. This is even true of the seasonal rainfall maps, unfortunately.
Most observers look at the monsoon rainfall data, which is clearly the most important season, without doubt. However, the rainfall in other seasons is also very important from a number of perspectives.
Here we are giving a detailed account of the pre-monsoon season rainfall that India received in the season just ended on May 31, 2020, including state wise, sub division wise, river wise and also district wise figures. Along with it, we also provide the figures of post monsoon figures for the just concluded water year. For the winter season (Jan-Feb 2020) we have only the figures for Jan 2020 since we missed downloading the Feb 2020 figures. We had already provided the monsoon 2019 figures through two blogs in October 2019[ii].
