New Delhi: New Delhi is currently grappling with an intense heatwave that shows no signs of abating before September 25. The ongoing heatwave has left residents sweltering under soaring temperatures, with the mercury consistently hitting highs well above normal for this time of year. The Indian Meteorological Department (IMD) has confirmed that no significant rainfall is expected until at least September 25, dashing hopes for immediate relief.Preventive measures The absence of rain has exacerbated the situation, making it one of the most challenging late-September heatwaves the capital has faced in recent years. The IMD attributes this extended dry spell to a delay in the withdrawal of the monsoon, which is typically expected to bring cooler temperatures and rain by mid-September. However, this year, the monsoon is retreating later than usual, prolonging the oppressive heat.Residents are being urged to exercise caution during the ongoing heatwave in Delhi. Key recommendations include staying hydrated by drinking plenty of water throughout the day and avoiding outdoor activities, especially during the hottest parts of the day, typically between late morning and early afternoon. Protective measures like wearing lightweight, light-colored clothing, using sunscreen, and wearing hats or sunglasses are also advised to minimize exposure to the suns harmful rays.Change in weather patterns neededThe prolonged heat has heightened concerns about health risks, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions like heart disease, respiratory issues, or diabetes.As Delhi waits for relief, the focus remains on weather updates and advisories from the IMD, which will continue to monitor the situation closely. While the heatwave is expected to persist, a change in weather patterns could bring the much-needed rain and cooler temperatures by the end of September.
