CHARLESTON — A stalled frontal system is washing out the weekend and prompting flash flood watches and coastal flood advisories in the Carolinas.


Heavy thunderstorms brought street floods Saturday both in Charleston and near Wilmington, North Carolina.


A flash flood watch, meaning flash flooding is possible, was posted through Sunday for 16 counties in central North Carolina and six in northeastern South Carolina. The National Weather Service in Raleigh said the stalled boundary will bring moderate to heavy rainfall through the weekend. By late Saturday, as much as 2 inches had fallen in some areas.


The Weather Service also posted coastal flood advisories from Wilmington south through Georgia. It warned that high spring tides, winds blowing on shore and the full moon could combine to cause moderate coastal flooding Saturday night.
