North Carolina Flood Watch

Location of streamgages where the water level is currently at or above National Weather Service (NWS) flood stage (the stage at which stream banks overflow or property damage may occur) or at high flow are shown on the map below.

The high flow conditions are expressed as percentiles that compare the current (i.e., within the past several hours) instantaneous flow to period of record daily mean flows for the current date.
