Rainfall data of August 2024 of some towns in Sub-Himalayan W Bengal and Sikkim

The National Highway 10 (NH10) which connects Siliguri to Gangtok and is the lifeline for Sikkim and Kalimpong district runs along the river valley almost hugging the banks of the river for almost 50 odd km. The monsoons extracted a heavy price for this closeness in Aug2024 - the highway was closed for almost 20 days due to landslides and erosion.
As per the above data:
  • Darjeeling, Kalimpong (in West Bengal), Gangtok, Mangan, Damthang (in Sikkim) recd almost normal rainfall.
  • Kalimpong, Siliguri, Jhallong, Alipur Duar (W Bengal) and Dentam in Sikkim recd went deficient in rainfall.
  • Most of the rainfall occurred in the first half of the month (see below).
    This was undoubtedly due to the low pressure areas and depressions which formed in the Bay of Bengal and moved towards western India, which resulted in surplus rainfall in those parts towards the end of Aug2024 (see above).
    Major Landslide
    A major landslide occurred in Sikkim on 20Aug2024 at Dipu Dara, just above NHPC Stage V Power House at Baluatar.
    We have covered the entire incident in our previous blog report

    Documentation of a part of the above report was supported by Royal Enfield, as part of their Social Mission Initiative

A document from the past: my (restored) photo of the Oct1968 disaster in the Darjeeling-Sikkim Himalaya



The Story behind the above Photo:
I still have vivid and frightening memories of the Oct 1968 Disaster which engulfed the entire Darjeeling-Sikkim Himalayas more than 50yrs ago.
I was 17 then, a student of St Joseph's College, Darjeeling who had come home to Kalimpong during the Puja vacations in the first week of October.
Then all of a sudden it started raining...
Strange that it was raining so heavily when we normally expected fine weather with an occasional shower. Stranger still, that the torrential downpours continued thru the day and night and yet another day and another night ... and for 4 days.
I don't recollect much lightning or thunder so I presume now it wasn't any cyclone or depression which had moved up from the Bay (of Bengal). I just remember the steady and heavy drumming of incessant rain. I also don't recall any panic or concern either among the local people or in government circles.
Meanwhile it just rained and rained and rained.
On the fourth night, I distinctly remember going to bed and hearing muffled explosions at night - landslides were taking place somewhere and reasonably close by...
On the fifth day morning, it stopped raining and suddenly we saw patches of blue skies.. and in the silence with no heavy rain, all I heard was sounds of water - water gushing out of crevices, trickling down some hidden corner, streets which had turned into rivers, water pounding down jhoras (natural drains), and the roar of the Teesta river way below my home in Tirpai, Kalimpong.
And there was also death.
It was everywhere - I saw the carcass of cows which had been buried in a landslide below our home, and near Nandu Ram's Wool Godown (now the CST - Central School for TIbetans) barely 5 mins walk from my home, some 15 people died in a huge landslide (refer the 'explosions'). Further down, in Dungra bustee, a jhora had burst its banks and swept away an entire clan of 7 of our relatives.
My little hamlet, Tirpai was marooned, cut off from the town of Kalimpong which was barely a kilometer away, and Kalimpong itself was marooned from Siliguri with the highway being decimated by landslides.
So we heard new sounds - sounds of helicopters as they dropped supplies and food, up at the army cantonment in Durpin.
I heard that the iconic Anderson bridge at Teesta bazar had been been swept away and that was when I and 2 friends walked down 16kms to photograph the destruction and havoc caused in the mother of all disasters in the Darjeeling- Sikkim Himalaya.
Realizing that most readers of this blog would not have even been born when the Oct 1968 disaster occurred and therefore would not understand the significance of the photo on top, I am attaching an image of the majestic Anderson Bridge which was washed away during the event. It was constructed in 1933 and named after John Anderson, Governor of Bengal.

Rainfall data Jun2016 - Darjeeling and Sikkim Himalaya


The monsoons arrived over the Darjeeling-Sikkim Himalaya almost 10 days late (14Jun instead of 05Jun2016), yet the first burst of rains after a drought-like situation brought in floods in many areas of Dooars and Alipur Duar.
Many parts of Sikkim received heavy rains leading to the dams releasing excess water on the Teesta and Rangit rivers - this would have contributed to the flooding in Jalpaiguri.
There were no major landslides in this region.

STH stormwatch -15Oct2013 : Feeling Phailin in the Himalayas -2


Very Severe Cyclone Phailin made landfall close to the Andhra/Odisha border on 12Oct2013 at approx 2100h (extensively covered in earlier STH stormwatch series of Oct2013).
Having moved inland it has been downgraded to a low pressure which is located in southwest Bihar (IMetD). Under the influence of this system, moisture laden clouds over the Darjeeling - Sikkim Himalayas have brought non-stop rainfall in the region for the last 24h and the rainfall continues as I write.
Rainfall figures from 0700h/ 14Oct to 0700h/ 15Oct2013 are shown below :-
a. Darjeeling  - 185 mm (source : STH ARG in Darjeeling).
b. Kalimpong - 141mm (source : IMD AWS - see above)
c. Siliguri       -   99mm (source : IMD AWS)
d. Gangtok     -   66mm (source : IMD AWS)
e. Gyalsing (W Sikkim) - 72mm (IMD AWS)

So far there are no reports of landslides (undoubtedly due to the less intensity of the rain) but this unseasonal rainfall will certainly cause :
a. Crop damage in this region
b. Flooding in the plains of Bengal.
