The India Meteorological Department (IMD) has issued a severe heatwave alert spanning large swathes of north and central India. The latest bulletin, released on April 27, indicates that extreme heat conditions are very likely to persist across Uttar Pradesh, Delhi, Rajasthan, Madhya Pradesh, Bihar, and Gujarat over the next 24 hours.
This warning follows a day of scorching temperatures on April 26, where many parts of India recorded readings between 40°C and 46°C. Akola in Maharashtra registered a blistering 46.9°C, marking one of the highest temperatures recorded this season.
Regions Under Heat Stress
The IMD's forecast highlights the continuation of a severe early summer surge. Beyond north and central India, hot and humid conditions are also anticipated in southern states such as Tamil Nadu, Kerala, and Andhra Pradesh. Additionally, 'warm night' conditions are expected in parts of north and central India, offering little overnight relief from the heat.
Several regions, including sections of Uttar Pradesh, Rajasthan, and Madhya Pradesh, are already experiencing temperatures more than 5°C above their seasonal averages, exacerbating the impact of the heatwave.
Specific Areas with Heatwave Conditions Today:
- Uttar Pradesh
- Bihar
- Rajasthan
- Madhya Pradesh
- Delhi
- Haryana
- Punjab
- Gujarat and Vidarbha
- Parts of Himachal Pradesh and Jammu & Kashmir
Coastal and southern regions are set to experience hot and humid weather, which will elevate discomfort and health risks, even if temperatures are comparatively lower than the interior.
Outlook and Health Advisories
The IMD predicts little to no immediate change in maximum temperatures across northwest India for the next 24 hours. However, a gradual drop of 3-5°C is anticipated between April 28 and May 1 in northern and eastern regions, potentially offering some respite. Central India may see a more moderate dip of 2-3°C over the same period.
Authorities have intensified health advisories, particularly for areas under red alert, where there is a very high likelihood of heat illness and heat stroke across all age groups. Orange alert zones also pose significant risks, especially for vulnerable populations such as the elderly, children, and individuals with chronic illnesses.
Public Health Recommendations:
- Avoid prolonged sun exposure.
- Stay hydrated by drinking plenty of fluids, even if not thirsty.
- Wear light, loose-fitting cotton clothing.
- Use protective gear like hats or umbrellas when outdoors.
- Consume traditional cooling drinks such as lassi, buttermilk, and lemon water.
Beyond public health, the heatwave is also impacting agriculture. Farmers are advised to implement light and frequent irrigation, use mulching techniques, and provide shade protection for crops to minimize moisture loss and heat stress.
