Winter rains have commenced in the northern and western parts of Rajasthan. Heavy rainfall and hailstorm witnessed in many parts of Nagaur. The reason behind these rains can be attributed to an active Western Disturbance over Jammu and Kashmir. This Western Disturbance has induced a Cyclonic Circulation over Southwest Rajasthan and adjoining Pakistan. After the rains both day and night temperatures are expected to drop in the region.
