The maximum temperature in the capital could drop to 40-41 degrees Celsius by Friday.

New Delhi:

The maximum temperature in Delhi could drop slightly on Wednesday, but isolated areas could experience a heat wave.

At Safdarjung Observatory, Delhi’s base station, the maximum temperature is expected to be 43 degrees Celsius.

Many parts of Delhi had been reeling under a punishing heatwave for a fifth consecutive day on Tuesday.

Weather experts said a further disturbance from the west could bring some relief over the weekend.

Five out of 11 weather stations in Delhi recorded a heat wave on Tuesday.

Meteorological experts attributed the heatwave period to the absence of strong westerly disturbances and the incessant hot and dry westerly winds.

Mahesh Palawat, Vice President (Climate Change and Meteorology), Skymet Weather, said a new western disturbance could induce cyclonic circulation over Punjab and Haryana, leading to intermittent pre-monsoon activity in the Haryana, Punjab, northern Rajasthan and western Uttar Pradesh. from June 10.

The maximum temperature in the capital could drop to 40-41 degrees Celsius by Friday.

With the monsoon expected to cover eastern India by June 15, easterly winds will bring moisture and intensify pre-monsoon activity in northwest India.

Plawat said the monsoon would likely arrive in Delhi around the normal date of June 27-28, and there was no system in sight that could block its progress.

A clear picture will emerge in about a week, he said.

Last year, the IMD predicted that the monsoon would hit Delhi nearly two weeks before its usual date. However, he had only reached the capital on July 13, making it the most delayed in 19 years.

The monsoon entered a “pause” phase and there was virtually no progress from June 20 to July 8, Palawat recalled.

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.

Based on recorded absolute temperatures, a heat wave is declared when an area records a maximum temperature of 45 degrees Celsius.

A severe heat wave is declared if the maximum temperature rises above 47 degrees Celsius.
