New Delhi | Jagran News Desk: Delhi on Monday late night was covered with dust and storm as the weather turned windy. However, the relief days for Delhiites are over now as the maximum temperature at the Safdarjung Observatory is expected to breach the 40-degree mark on Tuesday and a heatwave will see it soaring to 44 degrees Celsius by Thursday. The IMD has issued a yellow alert warning for a heatwave spell in the national capital starting April 28.

Meanwhile, several parts of the national capital recorded their maximum temperature above the 42-degree mark, with Sports Complex being the warmest place in the city at 43.1 degrees Celsius.

Winds gusting up to 50 kilometres per hour and a drizzle provided slight relief from the heat in some areas on Monday night.

Partly cloudy weather due to a western disturbance over Afghanistan had provided some relief from a prolonged heatwave spell in northwest India. However, another punishing heatwave is in the offing, a Meteorological Department official said.

The maximum temperature may even rise to 46 degrees Celsius in parts of Delhi, he said.

Let us tell you that the India Meteorological Department (IMD) uses four colour codes for weather warnings -- green (no action needed), yellow (watch and stay updated), orange (be prepared) and red (take action)

The city has recorded eight heatwave days in April this year, the maximum since 11 such days witnessed in the month in 2010.

For the plains, a heatwave is declared when the maximum temperature is over 40 degrees Celsius and at least 4.5 notches above normal. A severe heatwave is declared if the departure from normal temperature is more than 6.4 notches, according to the IMD.

The weather department had earlier said northwest India and adjoining parts of central India are likely to see more intense and frequent heatwave conditions in April.

India recorded its warmest March in 122 years with a severe heatwave scorching large swathes of the country during the month.
