Monsoon 2019: State wise rainfall

The first blog on just concluded South West Monsoon 2019, gave the national picture and broad picture of month wise, state wise, sub division wise and river wise rainfall. This blog provides some details of rainfall in districts of each of the 36 states and Union Territories (UTs) of India.

NORTH INDIA Comprises of seven states: Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Punjab, Haryana, Chandigarh and Delhi.

Jammu & Kashmir IMD (India Meteorological Department) provides daily district wise rainfall table[i]. In this table, there are 22 districts listed for J & K. IMD also provides Statewise District Rainfall Map for all states on Daily basis[ii]. The end of monsoon map for J&K given below, provides names of just eight districts and % by which the rainfall in respective districts departed from Normal. That means the map gives no information about rainfall in at least 14 of the districts listed in the daily Rainfall Table.

The 14 districts (figures in bracket provide the rainfall departure from normal for the SW Monsoon 2019 as per IMD table for the whole season) not listed in the map include: Badgam (-27%), Bandipore (-19%), Doda (-29%), Ganderwal (-42%), Kargil (-44%), Kistwar (NO DATA), Kulgam (+18%), Kupwara (-28%), Pulwama (-44%), Rajouri (-66%), Ramban (-9%), Samba (-26%), Shopian (NO DATA), Srinagar (4%). Second major surprise here is that at least for two districts (Kistwar and Shopian) IMD has NO RAINFALL DATA!

Among the eight districts listed in the map, Jammu has the Excess deficit of 61 % and Baramulla, on the other end, has the Excess Surplus rainfall at 62%. Five (Leh Ladakah (-53%), Kathua (-48%), Anantnag (-31%), Punch (-30%), Udhampur (-26%)) of the remaining districts had deficit rainfall and Reasi had Surplus Rainfall at 49 above normal rains.

So out of 20 districts for which IMD has rainfall data in J&K, only three districts have above normal rainfall and 17 have deficit rainfall. IMD hence reports the state having 21% below normal rainfall. Five highest rainfall districts are: Reasi (1717 mm), Udhampur (992 mm), Kathua (705.5 mm), Samba (689 mm) & Punch (509 mm). Rest of the districts have below 400 mm rainfall with lowest rainfall reporting districts are: Leh & Ladakh (17.8 mm), Kargil (21.1 mm) and Pulwama (85.3 mm).

Himachal Pradesh Of the 12 districts in HP, three northern districts (Lahul & Spiti (-56%), Kinnaur (-52%) and Chamba (-45%)) have reported deficit rainfall, Bilaspur in SE part of the state has reported 26% surplus rain and rest of the eight districts have reported normal rainfall, thus the state reporting 10% below normal rains.

Four districts have reported above 1000 mm rainfall: Kangra (1309.3 mm), Hamirpur (1154 mm), Sirmaur (1144.5 mm) and Bilaspur (1099.5 mm). Some of the lowest rainfall is reported from: Kinnaur (120.4 mm), Lahul & Spiti (175), Kullu (562 mm), Chamba (573.4 mm).

Uttarakhand Out of 13 districts in Uttarakhand, six each are painted red (deficit rainfall) and green (normal rainfall) and only Bageshwar from Centre of the Eastern half of the state is painted light blue with rainfall 43% above normal. Five of the six deficit rainfall districts are in the western half of the state, Champawat being the only district from East reporting deficit rainfall with 21% below normal rains.

Six districts report above 1000 mm rainfall: Pithoragarh (1411.3 mm), Nainital (1287.8 mm), Rudraprayag (1260.6 mm), Bageshwar (1204.5 mm), Dehradun (1092 mm) and Champawat (1051.2 mm). Only two districts have below 700 mm rainfall: Tehri Garhwal (612.6 mm) and Haridwar (697.2 mm).

Punjab Out of 20 districts of Punjab, Kapurthala in central Punjab received Excess Surplus rainfall to the extent of 128%. Three other districts received excess rainfall: Muktasar (25%), Bathinda (20%), Patiala (39%) received Surplus Rainfall. Nine districts had normal rainfall, mostly in North and East. Seven districts had deficit rainfall, mostly in South and west: Firozpur (-50%), Sangrur (-36%), Amritsar (-32%), Jalandhar (-28%), Mansa (-27%), Moga (-26%), Barnala (-25%).

Five districts had above 700 mm rainfall: Gurdaspur (901.2 mm), Rupnagar (834.1 mm), Kapurthala (820.9 mm), Patiala (780.4 mm) ,Nawanshahr (777.7 mm). Six districts had, shockingly, below 300 mm rainfall: Firozpur (155 mm), Mansa (218.9 mm), Moga (242.6 mm), Sangrur (265.1 mm), Barnala (275 mm), Faridkot (275.8 mm).

Haryana The state has 21 districts, of which only two had normal rainfall: Sirsa (-13%) and Yamuna Nagar (-15%). 16 had deficit rainfall and three had Excess Deficit rainfall: Rohtak (-72%), Fatehabad (-63%) and Panipat (-62%). Thus state received 42% below normal rainfall during June-Sept 2019.

Just three districts had above 400 mm rainfall: Yamunanagar (700.5 mm), Ambala (628.1 mm) and Karnal (418.3 mm). Nine districts had below 200 mm rainfall: Fatehabad (102.7), Rohtak (141.7), Hisar (159.8), Jhajjar (162.3), Kaithal (172.3), Bhiwani (182.5), Sirsa (182.9), Panipat (184.3), Jind (197.2).

Chandigarh The single district Union Territory had 716.4 mm, rainfall, 15% below Long Period Average (LPA) or Normal Rainfall.

Delhi Should not this be shameful? For three (West Delhi, North West Delhi and Central Delhi) of the nine districts of National Capital, IMD has no rainfall data!

DELHI (UT)_COf the remaining districts, five have below normal and only North Delhi had normal (528.1 mm, -11%) rainfall. New Delhi, not shown on the map had 300.2 mm or 42% below normal rainfall. South Delhi, with 454.3 mm rainfall, is the only other district besides North Delhi, that had above 400 mm rainfall.

WEST INDIA There are seven states in Western India: Rajasthan, Gujarat, Madhya Pradesh, Maharashtra, Dadar & Nagar Haveli, Goa, Diu-Daman.

Rajasthan Even in a year when Rajasthan has been blessed with Excess rains with 40% above normal rainfall at 582.6 mm bounty, three of the 33 districts of the state had Deficit Rainfall: Hanumangarh (-43%) and Ganganagar (-27%) from W Rajasthan’s ten districts and Alwar (-32%) from East Rajasthan’s 23 districts.

In West Rajasthan, four districts had normal and four districts had Excess rains (Pali (54%), Nagaur (52%), Jodhpur (45%), Jalor (33%)). Pali (698.4 mm) had the highest rainfall and Ganganagar (147.8 mm) had the lowest rainfall. Thus West Rajasthan had 19% above normal rain with total June Sept rain of 315 mm.

In East Rajasthan, 13 of the 23 districts have Excess Surplus rainfall, five have surplus rainfall, four have normal rainfall and Alwar, as mentioned earlier, had deficit rainfall. Thus East Rajasthan had 53% above normal rain, with total season rain of 919.5 mm, almost three times that of West Rajasthan. Eight districts here had above 1000 mm, with Jhalawar having the highest rainfall of 1716.6 mm. Alwar had the lowest rainfall of East Rajasthan this season, with rainfall of 373.8 mm. Only Bharatpur and Karauli had below normal rainfall from East Rajasthan, besides Alwar.

Madhya Pradesh It has 51 districts, 31 in West MP and 20 in East MP.

West MP was classified as Excess Surplus state this year, with rainfall being 61% above normal. 20 districts of West MP had Excess Surplus Rain, six had excess and remaining five had normal rains. Datia is the only district in West MP which had below LPA rainfall with 5% deficit, its rainfall of 719.9 mm is the lowest in West MP. Mandsaur, with rainfall of 2018.6 mm, had the highest rainfall in the region, its rainfall being 157% above normal, also highest for the state. No doubt that was a major factor that created National crisis at the Gandhi Sagar Dam and downstream areas in Chambal basin. Agar-Malwa with 128% above normal rainfall had the second highest surplus rain in West MP this monsoon. 25 districts (all LE and E rainfall districts, except Sheopur, one of the Excess Rainfall district) has rainfall above 1000 mm.

Mandla district, with 1747.2 mm, has the highest rainfall in East MP. Shahdol, with 12% below LPA rainfall, had the highest deficit and lowest rainfall (869 mm) in East MP. All districts in East MP had above 1000 mm rainfall, except three: Sidhi, Shahdol and Satna. The Bundelkhand districts like Panna, Tikamgarh, Chhattarpur, Damoh, Katni and Dindori all had above 1000 mm rainfall.

Gujarat The state has 33 district and IMD has two divisions of it: Gujarat region with 21 districts and Saurashtra & Kutch with 12 districts. State had 43% above normal rains with rainfall of 993.3 mm.

In Gujarat region with 21 districts, two districts (Bharuch (62%) and Chhota Udepur (73%)) had Large Excess, 12 districts had Excess and seven districts had Normal rains. Twelve districts had above 1000 mm rains, of which the three highest rainfall districts were: Valsad (3089 mm), Dangs (3039.3) and Navsari (2363.8 mm). Patan district had the lowest rainfall in this region with 663.2 mm rain.

In Saurashtra and Kutch region with 12 districts, seasonal rainfall was 839.7 mm, huge 66% above LPA. Three districts (Junagarh, Jamnagar (98% above LPA, the highest % above normal in this region) and Gir Somnath) had over 1000 mm rainfall. Even Kutch, the arid desert region, with average annual rainfall of 376.3 mm rainfall had 681.6 mm rainfall, 81% above normal rains.

The India Meteorological Department (IMD) on Monday announced that the southwest monsoon has withdrawn from entire Gujarat state and north Arabian sea. After 2013, this year recorded the maximum rainfall in absolute terms and second-highest rainfall percentage against long period average (LPA). The year 2013 had recorded 1175 mm rainfall and it was 147% of the LPA. This year, the state has recorded 1159 mm rainfall and it was 142% of the LPA. This year, June has recorded 109 mm, July 222 mm, August 446 mm, September 338 mm and October 43 mm rainfall. All 33 districts have recorded more than 100% of seasonal rainfall whereas out of 251 talukas, only 7 recorded 251-500 mm rainfall. All other taluka recorded more than 501 mm (19.7 inches) rains.  (https://timesofindia.indiatimes.com/city/ahmedabad/monsoon-withdraws-from-gujarat/articleshow/71586638.cms)

Maharashtra The state with 36 districts is divided into four regions by IMD: Konkan (7 Districts), Madhya Maharashtra (10), Marathwada (8) and Vidarbha (11). During 2019 SW Monsoon, the state had 1328.5 mm rainfall, which was 32% above Long Period Average.

MAHARASHTRA_cAmong the seven districts of Konkan, four had above 4000 mm rainfall with the highest rainfall of 4945.6 mm (57% above normal) being in Raigarh district. Mumbai city with rainfall of 2730.8 mm (35% above normal) had the lowest rainfall among seven districts of the region. Three districts (Palghar (68%), Thane (68%) and Suburban Mumbai (66%)) were in Large Excess category, the rest in Excess Category.

Madhya Maharashtra had 1166.9 mm rainfall during the monsoon, 55% above normal. Five of the ten districts here had above 1000 mm rainfall. Kolhapur with 2927.5 mm (69% above normal) rainfall, had the highest rainfall and Solapur with 299.6 mm (38% BELOW normal, the only district of this region having below normal rainfall), almost one tenth of the Kolhapur rainfall, had the lowest rainfall. Pune had the highest % surplus rainfall at 105% in this region.

Solapur is clearly a misfit in this region, both in terms of quantum of rainfall and the huge departure in terms of being below normal rains as also the topographical/ altitude situation for most of the district. It should possibly be shifted to Marathwada region.

Marathwada is the only region in the Central and South India where the region had below normal rainfall, deficit being 12%. Bid (-27%) and Latur (-22%) were in Deficit rainfall category districts, rest of the six were in Normal category. However only Aurangabad (4% above normal) Nanded (0% departure) were having no deficit or above normal rainfall. Nanded with 814.4 mm had the highest rainfall of this region. Bid with 412.2 mm had the lowest rainfall.

Vidarbha too had above 1000 mm rainfall (1054.6 mm, 12% above normal) during SW Monsoon 2019.

Yavatmal (30% below normal) and Washim (20% below normal) are the two deficit districts in this region. Yavatmal, with 563.8 mm, had the lowest rainfall of this region.

NORTH EAST INDIA In North East India, there are eight states: Sikkim, Assam, Arunachal Pradesh, Manipur, Mizoram, Meghalaya, Nagaland and Tripura.

Sikkim The state with four districts had 1954 mm rainfall, 22% above normal. North Sikkim, with rainfall of 2244.1, 50% above normal, was in Excess category. South Sikkim, with rainfall of 1353.3 mm, 35% below normal, was in Deficit Category. East and West Sikkim were in Normal category with rainfall in between the two extremes.

Assam The state had 1334.3 mm rainfall, 10% below normal. Two districts were in Excess rainfall category: Dhemaji (2315.8 mm with 27% above normal rainfall) and Baksa (1824.5 mm with 49% above normal rainfall). Seven districts were in Deficit and One district (Darrang with rainfall of 368.9 mm, 71% below normal) in Excess Deficit category. Remaining 17 districts were in Normal rainfall category. Besides Dhemaji, five other districts had over 2000 mm rainfall: Kokrajhar (3050.3 mm, 13% above normal); Chirang (2682.9 mm, 17% above normal); Bongaigaon (2493.6 mm, 8% above normal); Barpeta (2285.4 mm, 4% below normal); Lakhimpur (2066.2 mm, 3% above normal). Nine districts had below 1000 mm rainfall. Karbi Analog had the second highest deficit at 43% and second lowest rainfall at 487.8 mm.

Arunachal Pradesh It had rainfall of 1538.2 mm, 11% below normal. Only Lower Dibang Valley district was in Large Excess category with rainfall of 2797 mm, 65% above average. Five districts were in Deficit and Ten in Normal Category. Besides Lower Dibang Valley, three other districts had above 2000 mm rainfall: East Siang (2741.3 mm, 14% below normal), West Siang (2019.2 mm, 1% below) and Papum-Pare (2007.5 mm, 9% below normal). Lower Subansiri had the lowest rainfall at 829.2 mm (4% above normal). Tawang (it had the highest deficit at 54%) and East Kameng were the only other districts with rainfall below 1000 mm.

Manipur For third year in a row, Manipur is the highest rainfall deficit state among all states, deficit being 56% this year with rainfall of 620.8 mm. One possible reason for this is that IMD has been giving normal rainfall of Tamenglong at 6852.4 mm, but its rainfall has been less than 25% of that (e.g. 1510.7 mm this year, by far the highest rainfall of the state). This possibly needs correction. Chandel (352.5 mm) is showing the highest deficit of 82% and has the lowest rainfall of the state. Thoubal, with 409.4 mm rainfall, is the only other district with below 500 mm rainfall. All nine districts show below LPA rainfall, Imphal West is the only district in Normal Rainfall category with 9% deficit.

Mizoram The state has 1506.9 mm rainfall, 9% below normal. However, out of 9 districts, IMD has NO DATA for Chhimtuipui district, the district is mentioned in the IMD table, but not on IMD map. Lunglei district, with rainfall of 2121.2 mm (18% above normal) has the highest rainfall. Serchhip has the lowest rainfall: 877.9 mm rainfall, 42% below normal.

Meghalaya The state received 2431.8 mm rainfall, 15% below normal. East Khasi Hill, with rainfall of 5425 mm (20% above normal) has the highest rainfall among seven districts of the state. West Garo Hills has the lowest rainfall: 1255.6 mm (34% below normal). Jaintia Hills have the highest deficit of 49%.

Nagaland It received 998.1 mm rainfall, 13% below normal. Tuensang has the highest rainfall of 1282.3 mm (7% below normal). Kiphire has the lowest rainfall: 512.3 mm (17% below normal).

Tripura 1382.9 mm was the rainfall of the state, 5% below normal. Dhalai has the highest rainfall at 1523.5 mm and West Tripura with 1226.3 mm has the lowest rainfall.

ISLANDS The Andaman & Nicobar Islands from the East and Lakshdweep Islands from the west are included here.

In Conclusion The above summary table shows that West and South Zones have had most of the Large Excess and none of the Large Deficit districts. All the Large Deficit and most of the Deficit districts are in North, East and NE zones.

At the outset we must be appreciative of IMD efforts at promptly providing so much data about the rainfall in India promptly.

However, possibly most shocking fact here is the NO DATA column. IMD still does not have data for at least 11 districts, including three districts of the National Capital. How can that be acceptable situation for India’s premier Meteorological agency?

And here we have not even started looking at the quality of the data.
