The minimum temperature dropped to 14.4° Celsius in Calcutta on Saturday, 2.5° below normal, as cold northwesterly winds made strong inroads into southBengal. A gap in the extra-tropical storms has allowed the northwesterly winds free access to Bengal, said Met officials. A powerful Western Disturbance can also cause rain and snow in Sikkim and the upper reaches of Darjeeling. In south Bengal, Western Disturbances prevent the free flow of northwesterly winds, thereby causing a rise in night temperatures. Previous Western Disturbances have triggered snowfall in states like Kashmir and Himachal Pradesh.
