Heatwave nearing its end, west Rajasthan, Kerala remain hotspots: IMD

The national capital recorded a temperature of 38.2 degrees Celsius on Wednesday, a notch below the season’s average.

The India Meteorological Department (IMD) on Thursday announced that the heatwave is nearing its end across the nation. However, pockets in West Rajasthan and Kerala are still under the grip of the heatwave, prompting authorities to issue alerts.

While the heatwave alert remains in place for West Rajasthan, IMD scientist Soma Sen said, it has been downgraded to a yellow alert due to mitigating factors.

Sen said, “We have issued it with a yellow alert because we don’t have a lot of hope for the impact.” She attributed the change in weather patterns to a strong moisture flow originating from the Bay of Bengal. This influx is expected to usher in thunderstorm activity across various regions.

Multiple weather systems are expected to influence various parts of the country in the coming days, bringing with them rainfall, thunderstorms, lightning, and gusty winds, according to IMD.
