NEW DELHI - Temperatures passed 50 degrees Celsius (122 Fahrenheit) in northern India on Saturday as an unrelenting heatwave triggered warnings of water shortages and heatstroke.
The thermometer hit 50.6 degrees Celsius (123 Fahrenheit) in the Rajasthan desert city of Churu, the weather department said.
All of Rajasthan suffered in severe heat, with several cities hitting maximum temperatures above 47 Celsius.
In May 2016, Phalodi in Rajasthan recorded India's highest-ever temperature of 51 Celsius (123.8 Fahrenheit).
The Indian Meteorological Department said severe heat could stay for up to a week across Rajasthan, Maharashtra, Madhya Pradesh, Punjab, Haryana and Uttar Pradesh states.
Several deaths from heatstroke have already been recorded.
A red alert severe heat warning was issued in New Delhi as temperatures passed 46 Celsius, and residents were advised not to go out during the hottest hours of the day.
Even in the hill state of Himachal Pradesh, where many wealthy Indians go to escape the summer heat, temperatures reached 44.9 Celsius in Una.

In the western state of Maharashtra, farmers struggled to find water for thirsty animals and crops.
"We have to source water tankers from nearby villages as water reserves, lakes and rivers have dried up," said Rajesh Chandrakant, a resident of Beed, one of the worst-hit districts. "Farmers only get water every three days for their livestock."
Raghunath Tonde, a farmer with a family of seven, said the area has suffered worsening shortages for five years.
"There is no drinking water available for days on end, and we get one tanker every three days for the entire village," Tonde told AFP. "We are scared for our lives and livelihood."
The Hindustan Times said many Beed residents had stopped washing and cleaning clothes because of the water shortage.
