Answer 2

A Western Disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent. The moisture in these storms usually originates over the Mediterranean Sea and the Atlantic Ocean.The effect of western disturbance in Jammu and Kashmir and Himachal Pradesh will start retreating. Chances of thunderstorms in north Indian plains continue because of atmospheric instability. Some thunderstorms will be severe and are expected to bring hail (especially in parts of Uttar Pradesh, Punjaband Haryana).
