Temperatures were way above the normal level at several places in the two states.
The highest maximum temperature of 46 degrees was recorded at Nalgonda and Ramangundam in Telangana yesterday, according to a report from the Met office.
Temperatures rose due to winds blowing from Rajasthan and mercury levels are likely to rise further in the next couple of days, Met officials said.
Searing heat conditions forced people to stay indoors and busy roads in several towns in the two states wore a deserted look by afternoon.
