Delhi has recorded its hottest day of the year at 42.8 degrees Celsius, leading to a yellow alert from the India Meteorological Department (IMD) for the coming days. The alert indicates that temperatures across the city are expected to remain high, with several areas recording temperatures between 42-44 degrees Celsius. The government has activated its Heatwave Action Plan 2026, focusing on healthcare preparedness and public awareness. Hospitals are preparing for a surge in heat-related illnesses, with dedicated 'cool rooms' and increased bed capacity. To combat rising temperatures, authorities are expanding access to drinking water by installing water coolers and ATMs, and ensuring water supply at various public locations. Schools are also being involved in the response, with plans for hydration reminders. Outdoor workers are particularly vulnerable, and employers are advised to provide shaded rest areas and adjust working hours to minimize heat exposure.
