Several areas in Chandigarh, Mohali and Panchkula witnessed outage for hours, with Mohali appearing to be the worst affected where power hadn't been restored in a few areas till late night. In Mohali's Sector 70, a man out for a morning walk in a park sustained a leg fracture and severe head injuries after a tree collapsed on him. Fire officer Rajinder Pal said Ashwani Mittal was taken to a hospital. He is said to be stable. In Phase 7, a child had a close shave when a peepal tree collapsed near a temple, residents said.

In Kharar, an electricity pole fell on a boundary wall of SCL Society, damaging a car. In Chandigarh, around 50 trees were uprooted, many of which came crashing down onto power lines. Fourteen electric poles were broken and over 135 disruptions were recorded in the morning. Traffic was diverted on several Chandigarh roads due to uprooted trees which damaged several vehicles. In Sector 63, parts of a solar power plant fell on a car. In Panchkula, a large tree fell in a residential area of Sector 9, while another collapsed inside Yavnika Park in Sector 5. Thousands in Mohali were without power as heavy damage to infrastructure delayed restoration work, officials said.

Though power was restored by 9 pm in some areas, places like Phase 2, Sector 121 and Barmajra were without power supply till filing of this report.
