So there was no tower work yesterday. Today, the chances are better, with ground temperatures well above freezing.
I spent some time yesterday looking at pictures from a remote-controlled video camera well up on the tower, watching various-sized sections of ice break free and plummet down. It was nothing you'd want to be beneath at ground level and there was no way anyone would have been able to work safely on the tower.
Today may be better -- but even cold, wet surfaces are dangerously slippery.
