Tropical Depression Nine - November 6-11, 1977

A tropical depression formed between the Greater Antilles and Bermuda on November 3rd.  This system drifted northeast until the 4th,
when high pressure built in to its north.  Thereafter, the system moved north of due west until reaching the 76th meridian longitude,
when it turned west of due north due to an upper level low across the Deep South.  Operationally, the National Hurricane Center tracked the
depression offshore North Carolina before dissipating it across the western subtropical Atlantic, but the North American surface analysis
series shows that the low pressure system associated with the depression moved northward into North Carolina and southeast Virginia,
before turning northeast across southern New England ahead of an extratropical cyclone approaching the low from the west.  The low
dissipated as it was leaving Maine on the morning of the 11th.

The storm total precipitation maps for the depression are shown below, using data supplied by the National Climatic Data Center
in Asheville, North Carolina.  Flooding across South Carolina, western North Carolina, and western Virginia was caused by a
combination of a closed cyclone aloft over the Deep South drawing in moisture from the tropical depression moving offshore
Florida, and can be considered a predecesor rainfall event to the depression, which is indirect in nature.  This flood event was
considered the worst across western North Carolina and western Virginia since 1940.
