New Delhi, Aug 20 (PTI) Rains continued to lash the national capital and neighbouring areas on Thursday, triggering long traffic snarls, uprooting trees and causing damage to property in many areas.

The Delhi Traffic Police remained busy clearing traffic on Narela-Bawana road, Raja Garden flyover, Jhandewalan Mandir, Jhilmil underpass,, Azadpur vegetable market, Sarai Pipal Thala, Jahangirpuri, Madanpur Khadar among other places.
The force continuously posted alerts on its Twitter handle to inform public about traffic snarls.
Similar scenes played out on Wednesday, as incessant rains pummelled the national capital region, submerging roads, underpasses and parks in waist-deep water and bringing traffic on key stretches to a virtual halt.
The flooding was particularly severe in Gurugram, where roads turned into small rivers and parks resemble swimming pools.
Just a few hours of rains flooded swatches of Delhi, spelling trouble for commuters who remained stuck for hours on water-logged roads.
Pictures and videos of vehicles and people wading through waist-deep water were widely shared on social media.
The rains also crippled electricity supply in many areas.
Civic bodies reported incidents of the uprooting of trees in a few areas due to the rains.
A boundary wall of a school in Saket collapsed, damaging several vehicles parked alongside it.
Mahesh Palawat of Skymet Weather, a private forecasting agency, said climate change had led to a change in rain pattern.
'Earlier, we used to witness continuous light rains over two-three days. Nowadays, the same quantum of rainfall occurs in just 2-3 hours. These extreme events have been taking place across the tropical region since the last 10 years,' he said. PTI GVS NIT CK
