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.
Here "Trunk 12" is local vernacular for Highway 12, which is where this camera is mounted. It's on the west side of the highway, looking southward toward what is known as Blue Mountain, which is comprised of a few houses scattered in the woods. Trunk 12 runs from Highway 1 at New Minas, in the north, to Highway 3, near Chester, in the south. This webcam is about one third of the way down from the north end of Trunk 12. It's also just south of Murphy Lake, a popular fishing and hunting spot.
