Relief expected from May 29
However, residents are likely to get some relief from May 29 onwards, as the IMD has forecast thunderstorm and rain activity in the city.
"Relief in heatwave conditions over the region is likely from May 29 due to a likely western disturbance along with a moisture incursion from the Bay of Bengal due to the likely formation of a lower tropospheric east-west trough," the IMD said.
On Tuesday, Ayanagar recorded a maximum temperature of 44.8 degrees Celsius, 2.7 notches above normal, while Ridge logged 44.6 degrees Celsius, 2.9 notches above normal.
