Weather experts attribute the absence of active Western Disturbances over north India and any significant system over south India to higher-than-normal temperatures in northwest India since March last week.

Due to the effect of a Western Disturbance over Afghanistan, the area received some relief last week with gloomy weather. A heatwave warning has been issued for the national capital, which will begin on April 28.

For weather warnings, the India Meteorological Department (IMD) utilises four colour codes: green (no action required), yellow (watch and remain informed), orange (be prepared), and red (be prepared) (take action).

According to the IMD, the heatwave might cause “moderate” health issues for vulnerable persons in impacted areas, including as babies, the elderly, and those with chronic ailments.

“Hence people of these regions should avoid heat exposure, wear lightweight, light-coloured, loose, cotton clothes and cover the head by use of cloth, hat or umbrella etc,” it said.

In April of this year, Delhi saw eight heatwave days, the most since the month of 2010 when it experienced 11 such days.

On Friday, Delhi might have partly overcast skies, light showers, and a dust storm with gusts up to 50 kmph, which could bring some relief.

A heatwave is proclaimed in the plains when the maximum temperature exceeds 40 degrees Celsius and is at least 4.5 degrees above average.

According to the IMD, a severe heatwave is defined as a temperature difference of more than 6.4 notches from normal.

The meteorological authority has previously stated that heatwaves will be more strong and frequent in northwest India and neighbouring regions of central India in April.

India recorded its warmest March in 122 years with a severe heatwave scorching large swathes of the country during the month. Parts of the country are also seeing wheat yields drop by up to 35 percent due to the unseasonal heat.
