A western disturbance as a cyclonic circulation over Afghanistan and neighbouring areas is likely to affect the northern hills. An induced cyclonic circulation over southwest Rajasthan is also persisting. “Under its influence, scattered to fairly widespread rain or snow is likely over western Himalayan region during November 14 to 16,” IMD said in its morning bulletin.
Thunderstorm or hailstorm is also likely over the western Himalayan region on November 14 and 15. “We are expecting wind speed to increase to 15 to 20 kmph from November 15 onwards. As soon as the western disturbance passes, wind speed will start picking up. Mininmum temperature will also increase till November 18,” said Kuldeep Shrivastava, director, Regional Weather Forecasting Centre.
