The mishap occurred on Dhakog-Banni road at around 11.30 am. The deceased, Dikshita of Naddi near Dharamshala, was returning from the Banni Mata Temple with her family. Five people were in the car at the time of the accident. According to officials, large rocks suddenly crashed down from the hillside and one boulder pierced the roof of the vehicle, fatally injuring the teenager. The India Meteorological Department (IMD), Shimla, said rainfall is likely to continue in Himachal till July 12, with spells of heavy showers expected at several places during thistime. The weather office sounded an orange alert for heavy to very heavy rainfall in Kangra, Mandi, Shimla and Solan districts on July 7, while a yellow alert for moderate to heavy rainfall was sounded in Bilaspur and Sirmaur districts. On July 8, the IMD sounded a similar yellow alert in Chamba, Kangra, Mandi, Solan and Sirmaur districts. It will be followed by a yellow alert of moderate to heavy rainfall again on July 9 in Mandi, Shimla, Solan and Sirmaur districts. On Monday, showers lashed several parts of Himachal, including in Shimla, Dharamshala, Kullu and Mandi. During the last 24 hours, the highest rainfall of 10 cm was recorded in Jogindarnagar, followed by Kangra Aero (7 cm), Sandhole (5 cm), Bangana (4 cm), Palampur (3 cm), Bharwain (3 cm), Saloni (3 cm), Sarahan (3 cm), Dharmshala (3 cm), and Manali (1 cm). Traffic was disrupted at Pagal Nala on the Larji-Sainj road in Kullu district due to flooding, officials said. Meanwhile, heavy rain lashed Naren in the Rampur area of Shimla district last night, triggering a flash flood in the Brandli Khad (stream). The flood damaged a sports ground and the cremation ground in Karsholi village; two to three vehicles were also buried under the debris. Retaining wall of historic Christ Church on Shimla's Ridge collapsed on Monday morning due to the rain. However,mayor Surender Chauhan assured its repair within the next three days. "We have planned the work, and the damaged retaining wall near the historic church will be rebuilt within the next two to three days," the mayor said. Learning lessons from the monsoon mayhem of 2023 and 2025, the state government decided to construct only box culverts on new roads in the state. "We have seen major destruction owing to the monsoon in the last three years. So the government has implemented a new drainage policy under which only box culverts will be constructed on new roads to prevent debris accumulation and waterlogging, thereby reducing damage to both roadways and orchards," said public works department minister Vikramaditya Singh told HT on Monday. Speaking about the new drainage policy, PWD minister said, "The policy was prepared after detailed technical assessment by the department and marks a decisive shift from reactive repair-based practices to preventive and scientific road management. Drainage has been recognized as a core engineering component of road construction and maintenance, rather than a supplementary feature, ensuring long-term durability of road assets," The policy also emphasises the use of modern drainage infrastructure that allows effective mechanical cleaning and reduces choking. He noted that the department is on high alert as the monsoon begins. A high-level review meeting was recently held with the department's secretary, engineer-in-chief, chief engineers, zonal officers, and superintending engineers. The meeting will review the availability of machinery across the state, the condition of roads, and disaster preparedness. "Instructions will be issued for the immediate deployment of machinery or resources wherever the need arises," he said. Constant coordination is being maintained with deputy commissioners, the state disaster management authority, SDRF and NDRF, he said. District administration in Lahaul Spiti has decided to use drones for relief and rescue this monsoon. A training program on load-carrying drone operations was organised on Monday in the conference hall of the deputy commissioner's office, Keylong, Kiran Bhadana. "The objective of this training was to make relief and rescue operations faster and more effective during natural disasters, said Bhadana, who is also head of the Lahaul-Spiti district disaster management authority....
