HYDERABAD, India (AFP) - At least 800 people have died in a major heatwave that has swept across India, melting roads in New Delhi as temperatures neared 50 deg C.
Hospitals were on alert to treat victims of heatstroke and the authorities advised people to stay indoors with no end in sight to the searing conditions.
In the worst-hit state of Andhra Pradesh, in the south, 551 people have died in the last week as temperatures hit 47 deg C on Monday. "The state government has taken up education programmes through television and other media to tell people not to venture into the outside without a cap, to drink water and other measures," said Mr P. Tulsi Rani, special commissioner for disaster management in the state. "We have also requested NGOs and government organisations to open up drinking water camps so that water will be readily available for all the people in the towns."
Large parts of India, including the capital New Delhi, have endured days of sweltering heat, prompting fears of power cuts as energy-guzzling air conditioners work overtime.
The Hindustan Times daily said the maximum temperature in the capital hit a two-year high of 45.5 deg C on Monday - 5 deg C higher than the seasonal average.
The paper carried a front-page photo of a main road in the city melting in the heat, its zebra pedestrian crossing stripes curling and spreading into the asphalt.
"It's baking hot out here - our outing has turned into a nightmare," said Ms Meena Sheshadri, a 37-year-old tourist from the western city of Pune who was visiting Delhi's India Gate monument with her children.
"My throat is parched, even though I've been constantly sipping water."
In Telangana state, which borders Andhra Pradesh in the south, 231 people have died in the last week as temperatures hit 48 deg Cs over the weekend.
In the western state of Orissa 11 people were confirmed to have died from the heat.
India's Meteorological Department issued a "Red Box" warning for the state Tuesday and Wednesday - meaning the maximum temperatures would remain above 45 deg C.
Another 13 people have died in the eastern state of West Bengal, where unions urged drivers in the city of Kolkata to stay off the roads during the day.
Hundreds of people - mainly from the poorest sections of society - die at the height of summer every year across the country, while tens of thousands suffer power cuts from an overburdened electricity grid.
India's power industry has long struggled to meet rapidly rising demand in Asia's third largest economy, with poorly maintained transmission lines and overloaded grids.
With no end in sight to the hot, dry conditions, the Hindustan Times warned that some of the worst-affected states could be plunged into drought before the monsoon rains arrive.
The monsoon is forecast to hit the southern state of Kerala towards the end of this month before sweeping across the country, but it will be weeks before the rains reach the arid northern plains.
