APSDMA issues heatwave warning for 64 mandals in Andhra

# Andhra Heatwave: 64 Mandals on High Alert

**By Staff Correspondent, The National Pulse, May 2, 2026**

The Andhra Pradesh State Disaster Management Authority (APSDMA) issued a severe heatwave warning on Saturday, May 2, 2026, for 64 mandals across the state as temperatures are forecasted to surpass 45°C. Driven by dry northwesterly winds and intense solar radiation, the sudden meteorological spike poses severe health risks to millions. Authorities have activated emergency protocols, advising residents to stay indoors between 11 AM and 4 PM, while local hospitals brace for an influx of heat-related illnesses, underscoring the escalating climate vulnerability of the coastal Indian state.

## The Anatomy of the Current Heatwave

As India enters the peak of its pre-monsoon summer, Andhra Pradesh is bearing the brunt of extreme thermal conditions. The APSDMA’s latest bulletin explicitly outlines that 64 mandals are under a ‘Severe Heatwave’ alert, a classification used when maximum temperatures record a departure of 6.4°C or more above the normal, or when the absolute maximum temperature breaches the 45°C to 47°C mark in the plains [Source: Hindustan Times | Additional: IMD Climate Data 2026].

Meteorologists attribute this extreme weather event to a combination of high-pressure atmospheric systems trapping heat over the southern peninsula and the delayed onset of cooling sea breezes along the Coromandel Coast. Furthermore, the residual effects of the shifting global El Niño-Southern Oscillation (ENSO) cycle have historically disrupted local thermal regulations, leaving regions like Andhra Pradesh exceptionally vulnerable during the month of May.

“We are witnessing a sustained anti-cyclonic circulation over the central and southern peninsular region, which is essentially acting as a heat dome,” explains Dr. Suresh Kumar, a senior climatologist monitoring South Asian weather patterns. “This suppresses cloud formation, allowing uninterrupted solar radiation to bake the landmass. The current crisis in Andhra Pradesh is a textbook manifestation of this atmospheric anomaly.”

The APSDMA has leveraged its state-of-the-art satellite tracking and cellular broadcast networks to send real-time SMS alerts to residents in the affected zones. The authority’s proactive approach aims to minimize casualties, contrasting sharply with the reactive measures of previous decades.

## Vulnerable Districts and the Wet-Bulb Threat

The heatwave’s footprint is vast, but its intensity is particularly concentrated in specific geographic pockets. Historically, districts in the Rayalaseema region and parts of Coastal Andhra face the most grueling conditions. Mandals within Palnadu, NTR, YSR Kadapa, Bapatla, and Anakapalli districts are experiencing some of the highest thermal spikes.

However, temperature alone does not tell the full story. Along the coastal districts of Andhra Pradesh, high ambient temperatures combine with elevated humidity levels from the Bay of Bengal to create dangerously high “wet-bulb” temperatures. A wet-bulb temperature measures heat stress on the human body by accounting for humidity, which restricts the body’s ability to cool itself through sweating.

When the wet-bulb temperature approaches 32°C, even healthy individuals can experience severe heat exhaustion after prolonged exposure. At higher thresholds, it becomes fatal. The current APSDMA warning tacitly acknowledges this dual threat, urging district collectors in coastal mandals to be just as vigilant as those in the arid, landlocked regions of Rayalaseema.

Urban centers within these mandals, such as Vijayawada and Guntur, face an exacerbated threat due to the Urban Heat Island (UHI) effect. Concrete infrastructure, a lack of green canopies, and immense heat exhaust from millions of air conditioning units can push localized city temperatures 3°C to 4°C higher than surrounding rural areas.

## Public Health Emergency Protocols

The immediate consequence of the APSDMA’s heatwave warning is a massive mobilization of the state’s public health infrastructure. Heat stroke and severe dehydration are the primary concerns. The Andhra Pradesh Health Department has directed all Primary Health Centres (PHCs) and district hospitals to ensure the availability of adequate life-saving medicines, intravenous fluids, and Oral Rehydration Solution (ORS) packets.

Special ‘Heat Stroke Wards’ equipped with air conditioning and ice packs have been operationalized in the worst-hit mandals. Authorities are acutely aware that the most vulnerable populations include daily wage earners, construction workers, agricultural laborers, the elderly, and children.

“Heatstroke is a severe medical emergency where the core body temperature rises above 104°F (40°C), leading to central nervous system dysfunction, delirium, and potentially organ failure,” warns Dr. Meenakshi Rao, a senior public health administrator in the state. “We are strictly advising the public to remain indoors between 11:00 AM and 4:00 PM. Hydration is non-negotiable. People must consume water, buttermilk, lemon water, and coconut water even if they do not feel thirsty.”

To mitigate occupational hazards, the state government has issued advisories under the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), altering working hours for rural laborers. Shifts are now being scheduled for early morning or late afternoon to prevent exertion during the most punishing hours of the day.

### APSDMA Public Safety Guidelines:
* **Stay Hydrated:** Drink sufficient water frequently.
* **Avoid Direct Sunlight:** Stay indoors or in shaded areas between 11 AM and 4 PM.
* **Wear Appropriate Clothing:** Opt for lightweight, light-colored, loose, and porous cotton clothes.
* **Protect Your Head:** Use an umbrella, hat, or a damp cloth on your head when outdoors.
* **Recognize Symptoms:** Be alert to signs of heat exhaustion, including dizziness, headache, nausea, heavy sweating, and extreme fatigue.

## Agricultural Sector Under Threat

The socioeconomic fallout of a severe heatwave extends far beyond immediate public health. Andhra Pradesh is deeply reliant on its agricultural output, and extreme thermal stress in May poses a dire threat to both standing crops and livestock.

The heatwave coincides with crucial stages for several horticultural crops. Mango orchards, a major economic driver in districts like Krishna and Chittoor, are highly susceptible to sudden fruit drop caused by heat stress. Similarly, vegetable crops and late-sown rabi crops face severe desiccation, demanding substantially more irrigation at a time when water resources are naturally depleting.

Livestock and poultry farming, immense industries in Andhra Pradesh, are also on high alert. Poultry birds are exceptionally vulnerable to heat stress due to their lack of sweat glands, leading to reduced egg production, lowered body weight, and in severe cases, mass mortality.

Ramesh Naidu, an agricultural economist monitoring the region, notes the cascading economic impacts. “When temperatures remain consistently above 42°C for consecutive days, the mortality rate in poultry farms can spike dramatically if active cooling systems fail. Furthermore, the rapid evaporation of surface water reduces fodder availability for cattle, distressing the rural dairy economy.”

The state’s veterinary departments have issued parallel advisories, recommending that farmers keep livestock in shaded areas, provide continuous access to fresh water, and avoid grazing cattle during the afternoon.

## Straining the Power Grid and Water Resources

As millions of residents turn to fans, air coolers, and air conditioners for relief, Andhra Pradesh’s power grid is experiencing unprecedented peak demand. The surge in electricity consumption places immense strain on power distribution networks, increasing the risk of localized transformer failures and blackouts—which, paradoxically, removes the very cooling systems keeping people safe.

The state’s energy department has been put on high alert to ensure uninterrupted power supply, particularly to hospitals, PHCs, and critical infrastructure. Discoms (Distribution Companies) are monitoring load balances meticulously, occasionally resorting to strategic load shedding in non-critical industrial sectors to ensure residential and medical power continuity.

Simultaneously, the heat accelerates the evaporation of critical surface water resources. Reservoirs that supply drinking water to major urban centers require careful monitoring during extreme summer events. While the state’s major dams currently hold functional reserves carried over from previous monsoons, the rapid depletion rate necessitates strict water conservation measures at the municipal level. Local civic bodies have been instructed to deploy water tankers to rural and urban fringes where piped water supply is either erratic or non-existent.

## Climate Change and the Escalating Frequency of Heat Extremes

The warning issued for the 64 mandals is not an isolated meteorological fluke; it is part of a broader, deeply concerning global trend. Long-term climate data analysis reveals that the frequency, duration, and intensity of heatwaves in the Indian subcontinent have increased exponentially over the last three decades.

According to various scientific bodies, including warnings from the Intergovernmental Panel on Climate Change (IPCC), South Asia is on the frontlines of global warming. The baseline average temperatures have shifted, meaning that what was once considered an extreme, once-in-a-decade heatwave is rapidly becoming an annual, normalized occurrence.

“We are no longer predicting a theoretical climate crisis; we are actively managing its daily manifestations,” states an independent climate policy analyst based in New Delhi. “The APSDMA’s swift response is commendable and life-saving, but disaster management alone cannot solve a systemic climate issue. The relentless warming of the Indian Ocean, coupled with localized land-use changes and deforestation, virtually guarantees that these 45°C-plus days will become more common.”

This reality has prompted the evolution of Heat Action Plans (HAPs) at the state and municipal levels. Andhra Pradesh has been a pioneer in developing comprehensive HAPs that integrate early warning systems, inter-agency coordination, and public capacity building. However, the sheer scale of the current 64-mandal alert tests the limits of these preventative frameworks.

## Conclusion: Key Takeaways and Future Outlook

The APSDMA’s heatwave warning for 64 mandals serves as a stark reminder of the lethal potential of extreme weather in May 2026. As temperatures hover dangerously close to the 45°C mark, the immediate priority remains the preservation of human life through hydration, shelter, and medical readiness.

**Key Takeaways:**
* **Widespread Impact:** 64 mandals across Andhra Pradesh are under severe heatwave alerts, prompting state-wide emergency responses.
* **Health and Labor:** Authorities strongly advise avoiding outdoor exposure during peak hours (11 AM – 4 PM) and have modified rural working hours to protect daily wage laborers.
* **Economic Strain:** The heat threatens agricultural yields, specifically mango orchards, while posing deadly risks to the state’s massive poultry and dairy sectors.
* **Systemic Stress:** Unprecedented electricity demand for cooling is testing the resilience of the state’s power grids.

Looking forward, the mitigation of heatwave disasters requires a dual approach. In the short term, strict adherence to APSDMA guidelines, community checking on vulnerable neighbors, and the swift treatment of heat exhaustion are critical to preventing mortality. In the long term, Andhra Pradesh—and India at large—must aggressively pursue climate-resilient urban planning. This includes expanding green cover, implementing cool-roof technologies, transitioning to sustainable agricultural practices, and fortifying power and water infrastructure to withstand a progressively warming planet.

Until the southwest monsoon arrives to provide desperately needed meteorological relief, the residents of the 64 affected mandals must remain vigilant, informed, and prepared to weather the extreme heat safely.
