Severe Heatwave Alert Issued Across India: Yellow and Red Warnings in Multiple States

India is bracing for a severe heatwave alert as temperatures rise sharply across the northern and central parts of the country. The India Meteorological Department (IMD) has issued yellow alerts for Delhi and parts of northern India and even red alerts for some areas in Telangana. The warnings are in effect for the next several days, starting April 24, 2025, as extreme weather conditions are expected to worsen.

What Is a Heatwave and What Do the Alerts Mean?

A heatwave is declared when temperatures are 4.5°C to 6.4°C above the normal average. When it goes beyond 6.4°C, it is classified as a severe heatwave.

• A yellow alert means “be aware” – the weather may cause discomfort or health issues.
• A red alert is more serious and warns of dangerous heat levels that can cause heat strokes, dehydration, and even fatalities.

The IMD uses these alerts to inform the public and local authorities to prepare in advance and take precautions.

Delhi Under Yellow Alert

Delhi residents are being warned to prepare for extremely hot days ahead. Temperatures in the capital are expected to rise above 44°C, starting April 24. The IMD has issued a yellow alert for at least two consecutive days, urging people to stay indoors during peak hours and stay hydrated.

Health officials have advised children, the elderly, and those with chronic illnesses to avoid going out in the afternoon. Authorities have also increased water distribution and are monitoring hospitals for heat-related cases.

Telangana on Red Alert

In southern India, Telangana, especially Hyderabad and surrounding districts, is facing an even more dangerous situation. A red alert has been issued in several areas where daytime temperatures are already nearing 46°C.

Interestingly, even night temperatures are expected to stay unusually warm, making it harder for people to recover from the heat. Health experts say warmer nights can increase stress on the body and disturb sleep, especially for those without access to cooling.

Schools Shut Early in Chhattisgarh

In a related move, the Chhattisgarh government has announced that summer vacations for schools will begin earlier than scheduled, due to the rising heat. The decision aims to protect children from exposure during the hottest parts of the day.

This early break highlights how seriously local governments are taking the heatwave warnings, putting public health before academic schedules.

Heatwave Across Northern and Central India

Apart from Delhi and Telangana, other regions including parts of Rajasthan, Uttar Pradesh, Madhya Pradesh, and Odisha are also experiencing high temperatures. These areas may soon see similar alerts issued if the heat continues to rise.

The IMD has advised farmers and outdoor workers to limit their activities during peak sunshine hours (usually between 12 PM and 4 PM), and to wear protective clothing and carry water at all times.

Tips to Stay Safe During a Heatwave

Health departments are urging people to follow these safety tips:

• Drink plenty of water – even if you don’t feel thirsty.
• Avoid going out during peak afternoon hours.
• Wear light, loose-fitting clothes.
• Use fans, coolers, or ACs where possible.
• Keep windows and curtains closed during the day to block heat.
• Check on elderly family members and neighbors who may need help.

If you or someone nearby shows signs of heat exhaustion or heat stroke—such as dizziness, high fever, confusion, or fainting—seek medical help immediately.

Is This the New Normal?

Experts warn that such extreme weather events are becoming more frequent due to climate change. Rising global temperatures are making heatwaves longer, more intense, and more dangerous. Urban areas, in particular, are feeling the heat more because of the urban heat island effect—where cities become hotter due to concrete, traffic, and reduced greenery.

The IMD has also reminded the public that the full summer season still lies ahead, and more heatwave phases may follow.

Conclusion

As much of India faces a severe heatwave alert, staying informed and prepared is key to staying safe. The next few days will be critical, especially for vulnerable groups. Governments, schools, and communities are responding quickly, but individual awareness and caution are equally important.

With climate patterns shifting rapidly, such weather warnings may become more common. For now, the focus remains on protecting lives, minimizing heat-related illnesses, and ensuring that everyone, from city dwellers to rural workers, has the resources to cope with the rising heat.
