As an intense heat wave continues to sweep through the city, the Indian Meteorological Department (IMD) on Sunday issued a yellow alert warning in parts of Delhi for Monday. The nation’s capital had recorded a maximum temperature of 43.9 degrees Celsius on Sunday, according to the Safdarjung Observatory. It was four notches above normal.
The day’s high stood at 46.7 degrees Celsius at the automatic weather station at the sports complex near Akshardham Temple, making it the hottest spot in the city. Najafgarh, Mungeshpur, Pitampura and Ridge stations recorded high temperatures of 46.4 degrees Celsius, 46.2 degrees Celsius, 45.8 degrees Celsius and 45.8 degrees Celsius, respectively.
The intense heat wave was mainly the result of the absence of strong western disturbances, according to meteorological experts. Relentless hot and dry westerly winds are also contributing, PTI news agency reported.
A major respite from the scorching heat is likely later this week – June 15-16 – as the weather bureau predicts moderate rain with thunderstorms over northern parts of the country, including the nation’s capital. “Scattered to fairly widespread light or moderate rain with thunderstorms or lightning most likely over Jammu, Kashmir, Ladakh, Gilgit-Baltistan and Muzaffarabad, Himachal Pradesh, Uttarakhand and eastern ‘Uttar Pradesh and isolated to scattered rains over Punjab, Haryana, Chandigarh and Delhi on June 15-16,’ IMD said in Sunday’s weather report.
The IMD issues four types of color coded warnings – green, yellow, amber and red. Green alert basically means no warning because the maximum and minimum temperatures are within the normal range. The yellow alert is a notice to consult the forecast before leaving. It is also the responsibility of city administrators to “stay abreast” of weather events that may affect daily life.
The orange alert is a call to take extra precautions. The red alert is issued in extreme heat conditions. When a red alert is issued, residents are advised not to leave the house without sufficient preparations.
A heat wave is declared when the maximum temperature is above 40 degrees Celsius and at least 4.5 notches above normal. A severe heat wave is declared if the deviation from normal temperature is more than 6.4 notches, according to the IMD.
