Unseasonal rain continued in Delhi and adjoining areas for the third consecutive day on Friday, disrupting normal life and disrupting traffic throughout the day, inundating dozens of important roads and uprooting several trees.
Meteorologists have predicted that inclement weather and rain are expected to continue over the weekend, although the intensity may drop slightly on Sunday.
The India Meteorological Department’s (IMD) base weather station at Safdarjung Observatory, Delhi, recorded 72 mm of rain on Thursday. Meanwhile, the station at Palam recorded 102 mm during the same period – an unusually high amount of rain at any time of the year, leave with the last week of September when the monsoon is at its final (and usually weakest) stage. it happens.
The figures till 5.30 pm on Friday were 8 mm for Safdarjung and 30.3 mm for Palam.
Almost incessant rains led to heavy waterlogging in several busy parts, bringing traffic to a standstill in the city for the second day in a row. Dozens of uprooted trees and broken vehicles including buses became obstacles for the passers-by.
Some commuters also shared photos of a pedestrian underpass at the revamped Central Vista Avenue, which was inaugurated recently. However, the Ministry of Housing and Urban Affairs said that all waterlogging measures have been taken. Officials said the issues in the stretch were a minor issue that was quickly resolved.
Several underpasses in the capital were inundated due to almost stagnant rain on Thursday and Friday, officials said.
Officials said that till 6 pm on Friday, the control room of Delhi Traffic Police received 12 calls related to waterlogging and 22 calls for uprooting of trees, besides 19 calls for traffic jams. Due to light rain till late in the night, the process of calls continued till late night.
“Vehicles on the roads were poor during morning and evening peak hours but improved as compared to the city on Thursday. This appears to be because authorities in neighboring cities like Gurugram told offices to work from home, while in Noida schools for young children were closed. Another reason for the better traffic conditions on Friday was that the rains in Delhi were not as strong as it was on Friday.
Scientists say that the rainy period is prolonging the delayed return of monsoon, which also brought down the mercury. The maximum temperature in Delhi on Friday dropped to 27.6 degrees Celsius, seven notches below the normal temperature for this time of the year. According to the IMD’s weekly forecast, the same region is likely to see day temperature on Saturday and Sunday.
This unusual rainfall in Delhi in late September is the result of the interaction of two weather systems – a Western Disturbance (WD) and a Low Pressure System – 250 km south-west of Delhi. But, now a fresh Western Disturbance is likely to continue this conversation due to which more rains may occur over Northwest India in the next two-three days.
“A new WD has formed and is lying over Afghanistan. A low pressure area is persisting over Northwest Madhya Pradesh. This is a rapid movement at the moment. The fresh WD could interact with the system and bring even more rain to parts of Northwest India. In Delhi also we are expecting moderate rain on Saturday,” said RK Jenamani, senior scientist, IMD.
According to a separate analysis of IMD’s gridded data by HT, which has a slight difference from the numbers released by the department, Delhi received (on average) 51 mm of rain for the 24 hours ended 8.30 am on Friday. It became the 13th rainiest day recorded in the last week of September since 1901, for which such records are available. According to the IMD gridded dataset, 51 mm of rain is the second highest ever in 2022. On July 1, the city had received 65 mm of rain.
The latest spell has also covered Delhi’s deficient monsoon. The total monsoon deficiency in Delhi on Thursday morning was 41%, which fell to 32.5% by Friday morning. In the month of September alone, the effect of Thursday’s rain was far more dramatic: it turned a 35% deficit into a 14% surplus for the month.
Mahesh Palawat, Vice President, Climate Change and Meteorology, Skymet Weather, said that the weather was created by unique conditions. The weather system was due to a low pressure area that had traveled from North Madhya Pradesh to southern parts of Uttar Pradesh. “After mid-September, the weather system formed due to low pressure areas usually does not travel to North India. They remain stable till the central parts of the country. This time, however, a low pressure system traveled further and resulted in heavy rains which makes it a bit unusual,” he said.
He said this would continue till Sunday. “We will see less rain on Saturday but will continue to rain intermittently with one or two heavy rains.”
