Friday, November 25: With the winter gradually setting in, temperatures across most Indian states have been steadily dropping over the past few weeks. The country’s northwestern region has been especially feeling the winter chill, and now, parts of Rajasthan look set to shiver some more under some unusually cold conditions.

As per the India Meteorological Department (IMD), a cold wave is expected to grip isolated pockets across the eastern half of Rajasthan during the next three days — from Friday to Sunday, November 25-27. This forecast marks one of the first cold wave warnings issued by the department this 2022 winter season.

Given this prediction, the IMD’s regional met centre in New Delhi has issued a yellow watch over East Rajasthan for the next three days. The advisory urges the residents to ‘be aware’ of the local weather situation and take precautions accordingly.

In the plain areas, the IMD declares a cold wave when the minimum temperatures are expected to fall 4.5°C to 6.4°C below the region’s average temperatures. However, a cold wave can also be announced directly if the actual temperature is expected to drop below the 4°C mark, irrespective of how far it deviates from the average.

Meanwhile, during the early hours of Friday, the minimum temperatures at many places in East Rajasthan were 1.6°C to 3°C below their respective averages. Isolated locations in West Rajasthan also witnessed similar deviations. Churu in West Rajasthan, at 5°C, recorded the lowest minimum temperature across the plain areas all over India.

Such cold waves can be dangerous, even lethal — according to an IMD report released last year, human deaths caused by cold waves were 76 times higher than those due to heat waves in the year 2020.

As many as 152 deaths were reported owing to the 99 days of cold waves that India recorded in 2020, as per the Ministry of Statistics. In fact, there has been a nearly 2.7 times increase in the number of cold wave days from 2017-2020, the report added.
