Nova Scotia highway webcams are operated by the Nova Scotia Department of Transportation and Infrastructure Renewal (TIR). Most are mounted on tall steel towers, most of which have weather sensors included on the tower. The sensors measure temperature, humidity, barometric pressure and wind direction and speed.
The webcam pic below is more or less real time and will update every 30 to 40 minutes, depending on conditions.
The Mt Thom highway camera is mounted on the southeast side of Highway 104, the Trans Canada Highway, looking northeast up the highway in the general direction of New Glasgow. The tower is south of the communities of Mt Thom and Upper Mt Thom, about 28 kilometres west-southwest of New Glasgow.
