Several reports of property damage emerged from across the capital as water entered the low-lying areas and weaker structures gave in to the water pressure. Morning traffic was severely affected by the #waterlogging on roads.

🌧️More rains forecast

The capital, along with the adjoining regions of Punjab and Haryana is expected to receive incessant rainfall for the next two days. Sunday’s excessive rains are primarily attributed to the shifting of the monsoon trough towards the north.

The monsoon trough is an extended low-pressure area, which drives #monsoon rainfall across the northern half of India as it runs along the Indo-Gangetic Plain.

As this trough shifts northwards towards the Himalayas, it attracts more moisture-laden air, causing torrential downpour across northern and eastern parts of the country.

.@IMDWeather reports that the monsoon trough is lying along the foothills of the Himalayas and the convergence of moist southerly winds from the Bay of Bengal will continue to bring heavy rains to the eastern parts of the country.

Heavy to very heavy rainfall is forecast over isolated parts of Punjab, Haryana and Delhi on till Wednesday. The monsoon trough at mean sea level passes through Ganganagar, Delhi, Lucknow, Patna and further towards the foothills of Himalayas.

Delhi is likely to embrace a generally cloudy sky, with light to moderate rain or thundershowers towards night on Sunday followed by a generally cloudy sky with heavy rains on Monday.

Haryana, Chandigarh and Delhi are predicted to witness widespread thunderstorms and rain at most places with heavy to very heavy falls at isolated places till Wednesday.

Rain brings respite

Despite the #flashflooding due to heavy rains within a short period of time, the showers came as a respite from the otherwise hot and humid weather of the north.

#Delhi has experienced a rainfall deficit over the last month actual precipitation of 81.5 mm against the normal of 180.6 mm— a 55 per cent deficit from normal.

While the maximum temperatures hovered at around 38°C earlier last week, it dropped to 35°C on Sunday. Further, on Monday morning, the capital witnessed a minimum temperature of 25.6°C— two notches below normal for this time of the year.

Forecasts suggest that the temperatures are likely to fall further with maximum and minimum temperatures expected to fall to 33°C and 24°C by Wednesday. However, after Thursday, the mercury levels may rise up again to settle at around 35°C.
