The India Meteorological Department issued a severe heatwave warning for Uttar Pradesh after temperatures crossed 45 °C [1].

This extreme weather event threatens public health and infrastructure across one of India's most populous states. The intensity of the heat increases the risk of heatstroke and water scarcity in urban centers.

On April 27, 2024, the IMD placed more than 60 districts under red alert status [2]. The weather agency monitored critical temperature spikes in several major cities, including Kanpur, Prayagraj, Lucknow, Noida, and Agra [1].

Officials said the red alert indicates a high level of danger to the population. The extreme heat has gripped these regions, forcing local authorities to implement emergency measures to protect citizens from the rising mercury [1].

The IMD continued to track the heatwave's movement across the state. The agency said that the temperatures exceeding 45 °C [1] represent a significant departure from normal seasonal averages for the period.

Local administrations in the affected districts have been advised to maintain vigilance. The red alert status for the 60-plus districts [2] requires immediate action to mitigate the impact of the heat on vulnerable populations, particularly outdoor workers, and the elderly.

“Temperatures crossed 45 °C”

The issuance of a red alert across more than 60 districts signifies a critical public health emergency. When temperatures exceed 45 °C, the human body struggles to thermoregulate, leading to a higher incidence of heat-related morbidity. This pattern of extreme heat in April 2024 underscores the increasing volatility of the pre-monsoon season in Northern India.
