Heavy rain, gusty winds, and hailstorms swept through Delhi and the National Capital Region, providing a break from a severe heatwave [1, 2].
The sudden shift in weather is significant because the region had been enduring scorching temperatures. This system brought a welcome respite to residents who had been facing extreme heat conditions [2, 3].
The weather event occurred around May 15 and 16, 2024 [1, 2]. While some reports indicate the rain began Wednesday evening, others place the primary event on Thursday evening [1, 2]. The storms brought a mix of heavy downpours and hail, which transformed the city's atmosphere and lowered the temperature.
In response to the shifting conditions, the India Meteorological Department issued an orange alert for Delhi on Thursday and Friday [1]. This alert warned of the potential for severe weather and hazardous conditions as the system moved through the capital.
The instability was not limited to the capital. The India Meteorological Department issued heavy-rain and storm alerts for 15 states [4]. These alerts covered a broad area of the country, including regions where maximum temperatures had been climbing.
Residents in the National Capital Region said the change was a pleasant shift in weather [1, 2]. The combination of rain and wind effectively broke the grip of the heatwave that had plagued the city [3].
“Heavy rain, gusty winds and hailstorms swept through Delhi”
The occurrence of severe thunderstorms and hail during a heatwave suggests a high level of atmospheric instability. When extreme heat is abruptly interrupted by intense precipitation and wind, it often indicates a strong pressure gradient or a significant weather system moving into the region, providing temporary cooling but potentially increasing the risk of flash flooding or wind damage.
