Just as sweltering heat sweeps up the country, Delhi recorded its second hottest April in 72 years with a monthly average maximum temperature of 40.2 degrees Celsius, the India Meteorological Department said on Friday.
Back in 2010, Delhi had recorded an average monthly maximum temperature of 40.4 degrees Celsius. Delhi experienced three prolonged heatwaves this month in the absence of periodic light rainfall and thundershowers which typify this time of the year due to the lack of active western disturbances, according to news agency PTI report.
Here are the top highlights to this story:
- With the exception of April 21, when the maximum temperature settled at 35.2 degrees Celsius, Delhi recorded above-normal maximum temperature on all other days. Additionally, the city recorded a high of 43.5 degrees Celsius on April 28 and April 29. This was the highest maximum temperature on an April day in Delhi in 12 years.
- The national capital had recorded a maximum temperature of 43.7 degrees Celsius on April 18, 2010. The all-time high temperature for the month is 45.6 degrees Celsius, which was recorded on April 29, 1941.
- Meanwhile, in the wake of the current heatwave, India’s peak power demand met or the highest supply in a day touched the all-time high of 204.65 GW on Thursday. The India Meteorological Department (IMD) said the spell of heatwave will persist over northwest and central India for the next five days and over east India for the next three days.
- An orange alert has been issued for Rajasthan, Madhya Pradesh, and the Vidarbha region of Maharashtra for the next four days. The IMD uses four colour codes for weather warnings. Green means no action needed, yellow refers to watch and stay updated, orange means be prepared while red alert means take action.
- The IMD said the heatwave could lead to “moderate” health concerns for vulnerable people such as infants, the elderly and people with chronic diseases. “Hence people should avoid heat exposure, wear lightweight and light-coloured cotton clothes and cover the head with a hat or umbrella,” it said. There is an increased likelihood of symptoms of heat illness in people who are either exposed to the sun for a prolonged period or doing heavy work, an IMD advisory read.
A heatwave is declared when the maximum temperature is over 40 degrees Celsius and at least 4.5 notches above normal. A severe heatwave is declared if the departure from normal temperature is more than 6.4 notches, according to the IMD.
