Delhi and several parts of the National Capital Region are likely to remain under generally cloudy skies with intermittent rain spells through August 14, according to the India Meteorological Department (IMD). The forecast comes after heavy rainfall caused widespread waterlogging and traffic disruptions across the region.
The IMD had issued a yellow alert for Delhi-NCR for August 8. The rain also brought down temperatures across the capital, with maximum temperatures remaining 3 to 7 degrees Celsius below the seasonal average.
Delhi records heavy rainfall
All 11 administrative districts of Delhi recorded significant rainfall during the 24-hour period ending at 8:30 am on August 8.
South Delhi recorded some of the highest rainfall totals. The automatic weather station at the Pharmaceutical Sciences and Research University recorded 165 mm of rain, while the IGNOU campus station recorded 138 mm and Aya Nagar received 115 mm.
Palam recorded 104.6 mm, Najafgarh 103.5 mm and Janakpuri 102.5 mm during the same observation period. At Safdarjung Observatory, the official baseline station for New Delhi, 98.7 mm of rainfall was recorded.
The neighbouring NCR cities also received significant rainfall. Gurgaon recorded 96.5 mm, while Ghaziabad received 33 mm and Noida 28.5 mm during the same 24-hour period.
Temperatures fall as rain continues
The widespread rainfall brought a sharp drop in temperatures across the capital. Daytime maximum temperatures ranged between 26.5 degrees Celsius and 28.4 degrees Celsius, compared with a climatological norm of around 34.2 degrees Celsius for this period.
Minimum temperatures were recorded between 21.7 degrees Celsius and 25.9 degrees Celsius, also remaining below seasonal averages. Relative humidity reached 100% at several monitoring stations, while easterly winds of 20 to 25 km/h added to the cool and damp conditions.
Why is Delhi receiving so much rain?
According to the IMD’s analysis, multiple weather systems are contributing to the current rainfall over Delhi-NCR.
The monsoon trough is passing across North India, while the remnants of a weakened low-pressure system are associated with a cyclonic circulation over northeast Rajasthan and neighbouring areas. A mid-tropospheric western disturbance is also interacting with the monsoon flow.
Delhi-NCR rain forecast till August 14
The IMD expects generally cloudy conditions with intermittent rain spells across Delhi and adjoining NCR cities, including Noida, Ghaziabad, Gurgaon and Faridabad, through August 14.
On Sunday, August 9, very light rain is possible from early morning to forenoon, with another light spell likely towards the evening. Temperatures are expected to rise slightly, with maximum temperatures between 33 and 35 degrees Celsius.
On Monday, August 10, the sky is expected to remain generally cloudy, with one or two spells of very light to light rain possible during the afternoon or evening.
On Tuesday, August 11, light rain is forecast from early morning to noon and again during the evening or night.
From Wednesday, August 12, to Friday, August 14, overcast conditions are expected to continue, with short spells of light rain possible between the forenoon and evening hours. Maximum temperatures are likely to remain between 32 and 35 degrees Celsius.
IMD issues waterlogging and travel advisory
The weather department has warned of localised waterlogging on major roads and low-lying underpasses, along with traffic congestion and reduced visibility during heavy downpours.
The IMD has advised commuters to check real-time traffic updates before travelling, follow directions issued by traffic authorities and avoid roads and underpasses that are prone to water accumulation during monsoon spells.
