Issuing a travel alert today, the DAO advised passengers, drivers, transport operators and the general public to remain vigilant while travelling through entry and exit points of the Valley, particularly during periods of heavy rain. The DAO said the monsoon has already begun and that heavy rainfall could trigger floods, landslides and other disasters. It urged travellers to remain alert to weather warnings issued by the Department of Hydrology and Meteorology. The administration said people should confirm road conditions with the police administration before travelling if there is any possibility of road obstruction due to floods or landslides.
