The state witnessed the chilliest weather and light rainfall along with the thunder storm and snowfall over the higher altitude areas in the capital and other higher places across state yesterday. Michael Das, Assistant Meteorologist, Gangtok Meteorological Center, informed that the Western Disturbance was hovering over Northern Nepal from 12th of January onwards and then it advanced to southern parts of Tibet autonomous Region and then northern part of Sikkim.
After January 13, the sky will remain clear as it used to. The maximum temperature was 12 to 13 degree Celsius and minimum temperature was 4 to 5 degree Celsius over Gangtok city, which is normal during this season.
The western disturbance lying over Southern TAR shifted southwards towards extreme north Sikkim on 16th January.
The Barometric pressure departure at 8:30 a.m. and 11:30 a.m. were observed to be -5 to -6 millibar which created a trough of low pressure area and hot dry air from Bay of Bengal through plains of Sub Himalayan West Bengal flowing at 1.2 KM above sea level drastically mixed with cold air from Tibetan plateau creating a region of turbulence or cyclonic circulation over the hills of Sikkim, Mr. Das added.
It was known that due to the same there were series of thunder storms from 1:30 a.m. to 4 p.m. on January 16 and light continuous rainfall from 2:40 p.m. to 12 a.m. Snowfall was observed over the higher hills of Ranka, Panthang and Chandmari.
