The Indian Meteorological Department Monday issued an Orange alert in Delhi following the sizzling heatwave as the temperature in the city breached the 47-degree mark.
The temperature in several parts of Delhi was recorded at over 45 degrees celsius as Mungeshpur topped the chart with 47.3℃.
Meanwhile, the IMD has also issued a severe heatwave warning in the neighbouring Haryana, Punjab, UP & parts of MP, and Rajasthan.
"Temp varying b/w 44°-47°. Shall continue for 4 more days. We advise people to venture out carefully as heat spell very severe," ANI quoted RK Jenamani, senior scientist IMD as saying.
A heat wave is declared when the maximum temperature is over 40 degrees Celsius and at least 4.5 notches above normal.
