North India is currently facing an intense heatwave, with temperatures expected to soar to nearly 45 degrees Celsius in various regions on Sunday. This extreme weather event is attributed to a strong high-pressure system that has settled over the northern plains, creating a 'pressure cooker' effect by trapping hot air. States like Uttar Pradesh and West Rajasthan are particularly affected, with cities such as Prayagraj and Barmer recording temperatures close to 48 degrees Celsius. The situation is worsened by a lack of pre-monsoon showers, leaving the soil dry and unable to absorb heat, which further elevates air temperatures. In eastern India, high humidity levels in states like Jharkhand and West Bengal have led to a significant rise in the heat index, intensifying the oppressive conditions. However, a Western Disturbance is expected to approach the region by April 28, bringing moisture-laden winds that could lead to dust storms and light rainfall, providing some much-needed relief. Following this disturbance, temperatures are anticipated to fall below 42 degrees Celsius starting April 29, although summer conditions will continue.
