Delhi is expected to see a marginal dip in temperatures from Tuesday, with the possibility of drizzle in isolated parts of the city. The India Meteorological Department (IMD) has forecast partly cloudy skies on Tuesday, with a yellow alert issued for Wednesday, indicating one to two spells of light rain and gusty winds of up to 50km/hour.
The maximum temperature is likely to return close to normal and even below normal by Thursday, with daytime temperatures expected to hover between 39°C and 41°C till at least May 3. The city had recorded heatwave conditions for three consecutive days between Thursday and Saturday.
A heatwave is declared when the maximum temperature is at least 4.5° above normal and crosses 40°C; it is also declared if the maximum touches 45°C or more. No station met this criteria on Monday, similar to Sunday.
Mahesh Palawat, vice-president at Skymet, said the expected rain is likely due to a cyclonic circulation over central Pakistan and adjoining northwest Rajasthan. "On Monday, we already saw some rain in Rajasthan and it will move to Delhi, via Haryana, by Tuesday. More rain is likely on Wednesday and remnants of this spell are likely on Thursday too," he said.
