The soaring heat has taken 414 more lives since Thursday in Andhra Pradesh and Telangana alone, causing the death toll to rise above 1,700 in the two southern states of India.
The Met office has said that the two states are unlikely to get relief from the heat for the next two days.
"The heat wave warning has been extended for two more days," the Met department head in Hyderabad YK Reddy told NDTV. He further said that most of the deceased include labourers and elderly, who died of either sunstroke or dehydration.
The Telangana government is taking some measures to help contain deaths of more people, for which officials have been asked to provide adequate drinking water at public places, Telangana's Panchayat Raj minister KT Rama Rao said.
People have also been asked to remain indoors and officials have also ensured that there are enough staff in hospitals for emergency situations.
In other parts of the nation, the temperature remains above 40 degree Celsius. In Lucknow, the temperature has been recorded at 42.7 degree Celsius as of Thursday, IANS reports.
While Allahabad recorded 45.7 degree Celsius, mercury in Jhansi touched 45.3. Kanpur recorded 43 degree celsius.
