Srinagar, March 11 (ANI): A fresh spell of snowfall enveloped Jammu and Kashmir on Tuesday, plummeting temperature and forcing people to remain indoors. Trees, roads and rooftops of houses in mountainous regions were covered with snow. The fresh snowfall however, will help maintain the water-level in rivers and will boost the production of fruits and crops. Normal life in many parts of north India has also been adversely affected due to the harsh weather conditions. March is generally the month for snow to melt; but with the fresh snowfall even at the onset of the third month, the temperature has again dropped in many northern states such as Punjab, Haryana, Uttar Pradesh and New Delhi.
