The country continues to reel under severe heat wave conditions, with the weather department saying there will be no respite for the next two days.

Heat wave conditions persisted in Delhi on Sunday, with the mercury soaring up to 46.2 degrees Celsius. It is set to again breach the 45-degree mark on Monday.

"Mainly clear sky. Heat wave conditions likely at many places with severe heat wave at isolated pockets," the India Meteorological Department (IMD) has said.

"Heatwave conditions were observed in many places in isolated pockets over Delhi, south Uttar Pradesh, East Madhya Pradesh, Haryana, Chandigarh, and Saurashtra," the India Meteorological Department (IMD) said on Sunday as quoted by news agency ANI.

A heat wave is usually declared when the maximum temperature remains above 45 degrees Celsius for two consecutive days.

In the coming days, Delhiites will get major relief from blistering heat as the weather agency has predicted "dust storm or thunderstorm" for June 11 and 12 and "generally cloudy sky with light rain" for June 13, with a dip of two degrees in temperature.

After the onset of the Southwest monsoon was delayed by a week, the India Meteorological Department said it has further advanced in the south Arabian Sea, most parts of Lakshadweep and some parts of Kerala and south Tamil Nadu among other regions.

It also pointed out that the conditions were becoming favourable for the monsoon to advance into some parts of Northeastern states over the next 48 hours till Tuesday.
