Battered by hot and dry westerly winds, Delhi may see the ongoing heatwave spell peak on Sunday with the maximum temperature predicted to settle above 46 degrees Celsius in many areas, weather forecasters said.

The maximum temperature at the Safdarjung Observatory, Delhi's base station, is likely to rise to 45 degrees Celsius. The primary weather station had recorded a maximum temperature of 44.2 degrees Celsius on Saturday, which was the highest this year so far. It was 42.5 degrees Celsius on Friday.

Delhi on Saturday saw the maximum rise to 46.9 degrees Celsius at Sports Complex, 46.4 degrees Celsius at Pitampura, 45.8 degrees Celsius at Jafarpur, and 45.4 degrees Celsius at Ridge and Jayanagar.

The heatwave had pushed the maximum temperature to an unbearable high of 47.2 degrees Celsius at Mungeshpur and 47 degrees Celsius at Najafgarh.

Weather forecasters said the heatwave spell would worsen on Sunday. ''Hot and dry westerly winds sweeping the Delhi-NCR region will push the maximum further up. It is likely to hit the 45-degree mark at Safdarjung on Sunday,'' said Mahesh Palawan, Vice President (Meteorology and Climate Change), Skymet, a private weather forecasting agency. An 'orange' alert has been issued to caution people about a severe heatwave.

The IMD uses four-color codes -- green (no action needed), yellow (watch and stay updated), orange (be prepared), and red (take action)-- for weather warnings.

It said the heatwave could lead to ''moderate'' health concerns for vulnerable people -- infants, the elderly, and people with chronic diseases -- in affected areas. ''Hence people of these regions should avoid heat exposure, wear lightweight, light-colored, loose, cotton clothes and cover the head by use of cloth, hat or umbrella, etc,'' the Met office said.

''A cyclonic circulation over Punjab and Haryana will induce pre-monsoon activity which will provide some relief from the intense heat on Monday and Tuesday,'' Palawat said.

The IMD said a thunderstorm or a dust storm is likely in the national capital on Monday.

With scanty rains owing to feeble Western Disturbances, Delhi had recorded its second hottest April this year since 1951 with a monthly average maximum temperature of 40.2 degrees Celsius.

A heatwave at the end of that month had sent the maximum soaring to 46 and 47 degrees Celsius in several parts of the city.

Delhi received a minuscule 0.3 mm of rainfall in April against a monthly average of 12.2 mm. March saw no rainfall against a normal of 15.9 mm. The IMD had predicted above-normal temperatures in May.

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

Based on absolute recorded temperatures, a heatwave is declared when an area logs a maximum temperature of 45 degrees Celsius.

A severe heatwave is declared if the maximum temperature crosses the 47-degree Celsius mark.
