By March 13th the cyclone had deepened to the lowest pressure of any observed landfalling hurricane or winter storm
over the Southeast. Low pressure records were broken in cities across South and North Carolina. Barometric low
pressure reached 960 millibars in New England. Here is a satellite image of the storm near its peak (Fig 3.)
The storm caused nearly all interstate highways from Atlanta northward to close, as well as every major airport on the East coast. These impacts were unprecedented at the time.
