Light rains are expected in Delhi and its surrounding regions on Monday evening, which will bring down the mercury levels, providing relief to the people suffering from the scorching heat for the past few days.

According to the Indian Meteorological Department (IMD), rains may occur in a span of four to five hours and there is also the possibility of sandstorm and thunderstorm.

Cyclonic circulation over Rajasthan and South Westernly winds from the Arabian Sea kept temperatures below the 40 degrees Celsius mark on Monday and they would cause rains, said private weather forecaster Skymet.

There could be rains on Tuesday as well, which will keep the temperature low for the next two-three days, it said.
