Tropical Depression 28 over the western Caribbean, which eventually became Hurricane  Zeta, helped to provide copious tropical moisture over South Florida. As an upper level trough traversed aloft, additional deep moisture overspread the South Florida ahead of an approaching frontal boundary. This resulted in widespread rainfall over several days that lead to significant flooding across the east coast metro areas, which had already received several inches of rainfall from previous days.
The most impactful flooding occurred in Palm Beach County where several neighborhoods across the county experienced major street and field flooding, and several homes had water intrusion. The flooding lingered for several days in some of these areas.
