Blazing sun bakes city; 47.6°C at Palam
New Delhi, May 26: Delhi sweltered under a scorching heat wave on Tuesday as the mercury soared to 47.6 degrees Celsius in Palam area and most places recorded their maximum temperatures six notches above normal.
The Safdarjung Observatory, which provides representative figures for the city, recorded a maximum of 46 degrees Celsius. The last time the mercury at the Safdarjung weather station touched the 46-degrees-Celsius mark was on May 19, 2002, said Kuldeep Srivastava, the head of the regional forecasting centre of the India Meteorological Department (IMD).
The all-time record for Safdarjung in May is 47.2
degrees Celsius, recorded on May 29, 1944.
The last time the Palam Observatory recorded such a high temperature
in May — 47.6 degrees Celsius — was on May 18, 2010, Srivastava said.
The IMD said the weather stations at Lodhi Road and Aya Nagar recorded their respective maximum at 45.4 degrees and 46.8 degrees Celsius.
In large areas, a heat wave is declared when the maximum temperature is 45 degrees Celsius for two consecutive days and a severe heat wave is when the mercury touches the 47 degrees-mark for two days on the trot.
In small areas like Delhi, heat wave is declared if the temperature soars to 45 degrees Celsius even for a day, according to the IMD.
Mr Srivastava said some respite from the stifling heat was expected on Thursday due to a fresh western disturbance and easterly winds at lower levels.
