From Jeff Masters’ latest:
The weight of all that heavy snow on rooftops will create the danger of roof collapses. In addition to the heavy snow, the storm will bring coastal wind gusts over hurricane force, and moderate to major coastal flooding. During the peak of the storm, Friday night into Saturday morning, snowfall rates of 2 – 3″ per hour can be expected. …. The combination of heavy snow and high winds will make travel extremely dangerous or impossible, with near-zero visibility in white-out conditions. The snow and high winds are likely to cause many power outages.
Looks like NYC could get some serious snow:
