Yellow Alert in Delhi NCR: IMD Warns of Temperature Rising to 45 Degree Celsius From 19 May
The IMD has issued a yellow alert for Delhi, warning of continued heatwave conditions with temperatures likely to reach up to 45°C in isolated areas over the coming days, crossing critical thresholds that significantly increase heat-related health risks.

The weather department has cautioned that heatwave conditions are likely to persist in isolated pockets of Delhi from May 18 to May 23. The IMD has also warned that a gradual rise in maximum temperatures of about 3-5°C is expected across large parts of northwest India until May 21, after which conditions are likely to remain steady for a couple of days.
A heatwave is officially declared when the maximum temperature exceeds 40°C and is at least 4.5°C above the normal level. It can also be declared when temperatures reach 45°C or higher, regardless of the deviation from average conditions. A severe heatwave is recorded when the departure from normal exceeds 6.5°C, indicating extreme stress on public health and infrastructure.
The IMD further notes that a heatwave is confirmed only when such conditions are observed at a minimum of two stations within a meteorological subdivision for two consecutive days, with the official declaration made on the second day.
