The Indian Meteorological Department issued a five-day orange alert warning for a severe heatwave affecting Delhi and the surrounding National Capital Region [1].
This extreme weather event poses significant public health risks as temperatures climb toward record highs, threatening the safety of millions in one of the world's most populous urban areas.
The warning period spans from May 23 to May 28, 2026 [2]. The heatwave affects Delhi and nearby cities including Noida, Gurugram, and Ghaziabad [3]. According to meteorological data, temperatures in Delhi are approaching 46°C [4].
Conditions in the broader region are even more severe. In nearby Banda, temperatures have reached approximately 48.2°C [4]. The IMD said the current situation is a severe heatwave, a state that often triggers emergency measures to protect citizens from heatstroke and dehydration.
While the orange alert remains the primary warning for the heatwave, some reports indicate a yellow alert has also been issued for thunderstorms [5]. This suggests that while the scorching heat persists, there may be intermittent atmospheric instability providing brief periods of rain relief [5].
Local authorities said residents should limit outdoor activity during peak sun hours. The current forecast indicates that the furnace-like conditions will persist through the end of the week [2].

The convergence of a severe heatwave with potential thunderstorms indicates a volatile weather pattern for North India. While the orange alert signals a high risk of heat-related illness, the secondary yellow alert for thunderstorms suggests a shift in atmospheric pressure that could either mitigate the heat or create dangerous weather fluctuations in the NCR.
