From the Telegraph today : Good news for the Heritage Darjeeling Himalayan Railway (DHR)


Tindharia tracks to open soon
Siliguri, Dec. 15: The toy train tracks at Tindharia have been relaid soon and service from Siliguri to Gayabari is set to resume later this month.
“We plan to resume the service to Gayabari with a big bang. A special train will be operated from Siliguri Junction till Gayabari (34km) on that day. The date will probably be December 26. The work of relaying tracks at Tindharia has more or less been completed. We plan to conduct a trial run on the newly laid tracks this week,” Arun Kumar Sharma, the divisional railway manager of Katihar division of Northeast Frontier Railway, said over the phone from Katihar today.
A landslide at Paglajhora on NH55 in June 2010 disrupted the services from Siliguri to Kurseong.

Geological Survey of India (GSI) visit - Kalimpong 2013


Mr Debashish Bhattacharya Senior Geologist from GSI (Geological Survey of India) is in Kalimpong until tommorow 04Dec2013. The Scientist was here around the same time last year in 2012, during which STH had accompanied him on recce trips to most of the landslide affected places in Kalimpong. 

The monsoon season in 2013 was a rather mild one and there were hardly any new landslides this year and most of the major landslide zones from the years before showed very little signs any fresh activity. We have been with the geologist since the 28Nov2013 and will be going on our last field visit today 03Nov2013 to NimbongSuruk and Samthar villages.

STH Stormwatch (29Nov2013) : Death of a cyclone; very severe cyclone 'Lehar' withers away.


                         


IMetD update  : The depression over coastal Andhra Pradesh moved west-northwestwards and lay centred at 1730 hours IST of today, the 28th November 2013 over coastal Andhra Pradesh near latitude 16.00 N and longitude 80.80 E about 50 km southwest of Machillipatnam. It would move west-northwestwards and weaken further into a well marked low pressure area during next 06 hours.

The initial prediction for the storm was that the maximum surface wind speed could be as high as 170-180 km/hr, gusting up to 200 km/hr.Experts say the storm lost most of its intensity because of :-
  • Winds blowing form central India
  • The decrease of SST (Sea Surface Temperature) caused by the onset of winter.
  • Wind Shear
The Andra Pradesh government evacuated more the 45000 people from coastal areas with 30 NDRF (National Disaster Response Force) and 450 SDRF ( State Disaster Response Force ) personnel being involved in rescue operations. The state government also opened more than a 100 relief camps. Thanks to both the atmospheric factors that influenced the weakening of the storm and the prompt response from the govornment 'Lehar' has not and probably will not claim any lives now.

Travelling light

I know that Cyclone Helen is just about starting her grim dance of destruction into Andhra Pradesh and IMetD also warns of another depression which is following - yet I have some conferences to attend in Kolkata after which I hope to be attending this one in Delhi.
However, STH blogs and activity, will after a few days be continued by Rohan.

STH stormwatch (09Nov2013) : Low pressure over Andaman Sea

2013 seems to be ending with a bang, what with a low pressure brewing up in the Andaman sea in early Oct and mutating  into  Very Severe Cyclone Phailin within a week and  with Super Typhoon Haiyan literally obliterating parts of Philippines yesterday.
IMetD is now reporting another low pressure in the Andaman sea which it cautions will intensify into a well-marked low pressure area within 24 hrs - that is exactly what happened with Phailin.

STH stormwatch (07Nov2013) : A Mother of all Typhoons over the Philippines


Super Typhoon Haiyan is the strongest typhoon/storm of the year 2013 and as I write it is about to make landfall over Philippines, even as the typhoon season is drawing to a close.
It packs windspeeds of over 240km an hour and storm surges are expected to be over 5m (15ft) high . What is most distressing is it comes after the island has been lashed repeatedly by typhoons and a 7.2R quake rattled some parts of the island nation on 15Oct2013 causing death and huge fissures where water ingress would have deadly consequences.

Rainfall Data for Sub Himalayan West Bengal and Sikkim : October 2013






IMetD classifies its rainfall maps under four headers :
  • Winter - January to February
  • Pre-monsoon - March to May
  • Monsoon - June to September
  • Post Monsoon - October to December              
Slide - 1 - Shows the last rainfall map for the Monsoon season in 2013 ie from Jun-Sep2013. SHWB (Sub Himalyan West Bengal) and Sikkim went deficient in rainfall throughout the season receiving 15% less than the normal average.
Slide - 2 - Shows the predicted withdrawal pattern (in red dots) of the South Westerly monsoon along with actual trajectory that was traced (in green lines). The rain bearing winds withdrew entirely from the Indian sub-continent on the 21Oct2013. 
Slide - 3 - In the first month of the post monsoon season SHWB and Sikkim recieved 30% more rainfall than the normal average (154.2mm). The excess rainfall was the result of two days of incessant rainfall on the 14/15Oct2013 caused by Very Severe Cyclone 'Phailin' when most of this region received more than the whole months rainfall in just two days (Shown in last slide).
No major landslides were reported, perhaps because the entire Oct was otherwise dry.
