Telangana's heat divide: Why some districts are facing extreme temperatures than others?

Telangana's heat divide: Why some districts are facing extreme temperatures than others?

The Hindu22-04-2025
In 2024, Telangana witnessed a stark contrast in how different regions experienced the summer heat. Nalgonda district endured a staggering 81 heatwave days — the highest in the State . Close behind was Suryapet with 54 days. In contrast, districts like Hyderabad, Hanamkonda, Medak, Adilabad and Rajanna Sircilla recorded no heatwave days at all, according to the Telangana Heatwave Action Plan 2025. The HAP using districts as administrative units is said to be the first of its kind.
This uneven distribution, as per the report, is closely tied to topographical and climatic differences. Data from the last decade (2014-2024) shows that eastern and northern districts such as Mancherial, Jagtial and Peddapalli consistently record more than 10 heatwave days annually, while the western-central parts including Hyderabad, Medchal Malkajgiri and Rangareddy districts are at a higher elevation, and higher places generally stay a bit cooler, so they have fewer heatwave days.
The report said that in India, heat wave conditions are considered if the maximum temperature of a station reaches at least 40°C or more for plains, 37°C or more for coastal areas and at least 30°C or more for hilly regions, as per the HAP report. To track and respond to these risks, the Telangana State Development Planning Society (TGDPS) uses data from 1089 automated weather stations across the State to issue district-level forecasts and advisories.
The State's vulnerability map, created based on a decade of data, categorises mandals into five tiers — Severe, Critical, Semi-Critical, Vigilant and Safe. Six mandals fall under the 'Severe' category while 106 are marked as 'Critical' and 189 as 'Semi-Critical. Over 16.181 million people are in severe, critical and semi critical zones in the State. The plan's classification uses metrics such as the number of heatwave days and temperature anomalies over the past ten years.
The Telangana State Heatwave Action Plan was initially prepared in 2016 following High Court orders and guidelines from the National Disaster Management Authority (NDMA). The plan was revised annually, with updates in 2017, 2018, 2019, 2020, 2021 and 2024, incorporating regular inputs from NDMA and scientific institutions. For 2025, Telangana's Revenue (Disaster Management) department has initiated the revision of heatwave preparedness in collaboration with the district administration of 33 districts, line departments, IMD, TGDPS and UNICEF Hyderabad field office.

Dharali floods a wake-up call for IMD, NDMA to buck up—the Himalayan region is vulnerable

In a state that sees frequent cloudbursts and floods during the monsoon, and has been explicitly marked as a 'high vulnerability zone' for landslides by the National Disaster Management Authority (NDMA), the damage from the Dharali floods is not merely nature's fault. The blame also rests squarely on building norms, mass road construction and mining projects, and other anthropogenic activities that have exacerbated Uttarakhand's fragility. Dharali's floods struck in the absence of any weather warning, and authorities are still confused about the actual cause. While the Uttarakhand State Disaster Management Authority called it a cloudburst, the India Meteorological Department could not confirm it with the available data. Uttarkashi district recorded 12.7 cm of rain in 8 hours on 5 August; it is still lower than districts such as Haridwar and Dehradun, which got 15-30 cms of rain on the same day. The deadly flash floods and landslides in Uttarkashi on 5 August, in which 16 people were killed, highlight the problems of illegal riverbank constructions and inadequate warning systems. Videos of submerged villages, ravaging floods sweeping up buildings and cars in their tide, and stranded people have become an almost annual occurrence now in the Himalayan region. The floods should be another wake-up call for the IMD and the NDMA to buck up and ensure the safety of people and ecology in the Himalayas. And that is why Dharali is ThePrint's Newsmaker of the Week. What happened in Dharali? Dharali is a small hamlet 2,680 metres above sea level, situated 18 km from Gangotri, and is a common stopover for tourists and pilgrims going to one of the Char Dhams of Uttarakhand. It is dotted with hotels, restaurants, and homes built precariously close to the banks of the Kheerganga River that runs through the village. On Tuesday afternoon, a barrage of water descended upon the village and damaged houses, roads, and the one bridge connecting Dharali and Hershil, another area affected by the landslide. Satellite images from ISRO now show that deposits of mud and sediments from the floods cover all of the village. Alongside civilian settlements, an Army camp near Hershil too was impacted by the floods, although the number of people missing there hasn't been reported. The IMD had issued warnings of heavy to extremely heavy rainfall in all of Uttarakhand, including the Uttarkashi district, from 1 August onwards. But compared to other districts, Uttarkashi's rainfall during this monsoon was still pretty low. From 1 to 5 August, Uttarkashi's recorded rainfall was 6 per cent lower than the average rainfall it gets during this period. Over the monsoon season so far this year in the state, Uttarkashi has recorded 7 per cent lower rainfall than average. If there was indeed a cloudburst—100 mm of rain falling in one hour in a small area—then the IMD is not aware of it. The closest Automatic Weather System (AWS) station that could record this cloudburst is 7 km from Dharali, and it did not catch a cloudburst. But experts say that even without a cloudburst, the possibility of heavy rainfall causing this disaster is not unfounded. Dharali's location and slope explain it. 'The 'cloudburst' may have happened much higher at 12,000 ft above sea level, and Dharali is at 8,000 ft. Even this slope of 4,000 ft makes a huge difference to the intensity of the water flow,' Mahesh Palawat, vice president of meteorology and climate change at SkyMet Weather, told ThePrint. 'The canal is very narrow, and a lot of trees and mud could have been uprooted and swept along with the water.' If extremely heavy rainfall can cause such damage without a rare event like a cloudburst, it should leave the system working toward India's disaster preparedness thinking.

Cutting corners on safety Lessons from Kedarnath, Sikkim, Chamoli A little over a decade ago, in 2013, Uttarakhand saw the worst natural disaster ever, where more than 5,000 people died in the Kedarnath cloudburst and ensuing floods. The resounding conclusion of experts and environmentalists back then was that unplanned construction of hotels and buildings, as well as hydroelectric, mining, and road projects, had made Kedarnath a disaster 'waiting to happen.' Since then, the Himalayas have seen at least 10 other such extreme weather events, including the Kedarnath floods in 2024, the Himachal Pradesh floods in 2023, the Sikkim Glacial Lake Outburst Flood (GLOF) in 2023, and the Chamoli floods in 2021. After each disaster, the authorities vowed to strengthen early warning systems, implement construction rules, and bring about climate-resilient infrastructure in the hills. In Dharali, there were no AWS systems or Doppler Weather Radars of the IMD close enough to accurately predict the floods or the landslide and warn people to evacuate. Three days after the disaster, the authorities are still unsure about whether a cloudburst or a glacial lake outburst, or just heavy rainfall caused the event. But geologists in Uttarakhand have a bigger question: 'How many times will the government issue warnings, and then an incident like this happens with loss of life and property, and then the government gives compensation again? Why are we allowed to build in unsafe places at all?' said Y.P. Sundriyal, a geologist based in Uttarakhand. Evacuation measures are currently the need of the hour and are indeed being carried out swiftly by the NDRF, SDRF, and the Army. However, disaster management involves not just responding to a disaster but also preventing one. That is a steep curve India has to cover. (Edited by Ratan Priya)

NDMA to probe rising extreme weather events in U'khand, Himachal

Dehradun: In the wake of back-to-back extreme weather events in the Himalayan states of Uttarakhand and Himachal Pradesh, the National Disaster Management Authority (NDMA) has announced that a team of experts will soon be sent to Uttarakhand to study the recent flash flood-disaster in Dharali and assess the growing threat of such climate-linked incidents in the region. Rajendra Singh, member secretary of NDMA, said on Friday that a similar team recently completed a field assessment in Himachal Pradesh following a series of deadly landslides and floods last month. "The findings from both states will help us better understand why such high-impact events are occurring more frequently in both states," Singh said. He added that the visit to Uttarakhand will be undertaken after the Post-Disaster Needs Assessment (PDNA) and a scheduled tour of the affected region by an inter-ministerial expert group. Dharali village in Uttarkashi was devastated earlier this week after a massive flash flood — triggered by a suspected glacial debris collapse — flattened dozens of buildings and cut off road access. Rescue efforts are ongoing, with over 90 helicopter sorties flown to evacuate the stranded.

Uttarakhand flash floods: State seeks Doppler radars, high-tech warning systems

Uttarakhand has urged the Union government to set up three Doppler radars in the state's higher reaches, like Kedarnath and Bhagirathi valleys, and help it with high-tech early warning systems for flash floods and landslides to deal with extreme weather events. Climate change and environmental degradation have triggered a string of disasters in Uttarakhand. (PTI) The request was made days after flash floods in Uttarkashi. Climate change and environmental degradation have triggered a string of disasters in Uttarakhand over the last few years. 'We requested NDMA [the National Disaster Management Authority] to set up three Doppler radars in the higher reaches of Uttarakhand,' said secretary (home) Shailesh Bagauli on Friday. 'We have three Doppler radars. But three in higher reaches will help us in dealing with extreme weather there.' The Doppler radars provide advanced information, enhancing the lead time essential for saving lives and property in the event of a disaster associated with severe weather. Conventional radars can track and predict cyclones. Doppler radars provide detailed information on the internal wind flow and structure. The severity of the weather systems can thus be quantitatively estimated more accurately, and more precise warnings can be generated to save lives and property. Uttarakhand has Doppler radars at Lansdowne (Pauri Garhwal), Mukteshwar (Nainital), and Surkanda (Tehri Garhwal). They were set up a year after the 2013 flash floods in Kedarnath, which killed 4,127 people, under a programme to improve weather forecast services in the Himalayan states and help in reducing human losses due to extreme weather events. Activist Ajay Gautam, who has filed petitions related to disasters in the state, said higher Himalayan valleys are more susceptible to tragedies like the one in Kedarnath in 2013, and in Chamoli in 2021, when a glacial burst claimed 204 lives. He said such incidents will continue, and the government has to prepare and take measures to lessen human losses. 'One of the best ways to do this is to establish advanced warning systems and more Doppler radars, for which I had filed a plea in the Uttarakhand high court in the aftermath of the 2013 tragedy. Three have been set up, but we need more in higher reaches. The severity of the weather systems, many of which trigger landslides and cloud bursts, can help authorities to quantitatively estimate the weather more accurately and issue more precise warnings for saving human lives.' Over 51% of the state is in very high landslide susceptible zones, according to Dehradun's Wadia Institute of Himalayan Geology.
