Episode narrativeepisode_narrativeMultiple days of dense fog combined with below freezing temperatures led to rime ice forming on power lines over portions of south central North Dakota into the southern James River Valley. Many power lines had rime ice accumulations of over three inches diameter, which led to lines sagging and some snapping. This included not only distribution lines, but also main transmission lines which feed power to substations. Approximately 2,000 electric customers suffered power outages, with some outages lasting a couple of days. Through the event, linemen were repairing snapped lines and manually clearing ice off the lines to prevent further breakage. In addition, 14 wooden power poles were broken from the weight of the ice covered lines.
