SaveTheHills(STH) is a group of concerned citizens who are raising awareness about landslides in Darjeeling-Sikkim Himalaya.
Many landslides are the direct or indirect result of human interference and preventable if sufficient care is taken.
As such, unless we begin a comprehensive and sustained program towards landslide management, prevention and mitigation, the consequences of ignoring years of human callousness will, in the future be devastating.
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.
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.

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. Praful Rao, Kalimpong, Dist Darjeeling

Refer our earlier post on 09Nov2013. Today's IMetD (evening) update reports a WELL MARKED LOW having formed which is likely to intensify into a depression in the next 24hrs. You can keep abreast of the updates here
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. Praful Rao, Kalimpong, Dist Darjeeling.
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.
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.
