Hurricane Matthew: Flood Resources and Tools

Science Center Objects

During and after Hurricane Matthew, the USGS made flood-flow measurements, maintained streamgages, deployed over 390 instruments, and developed geospatial products to measure and communicate the extent of coastal and inland flooding.

October 2016 Hurricane Matthew Flood Event Viewer

The Flood Event Viewer provides access to USGS monitoring activities during Hurricane Matthew.

The USGS Flood Event Viewer helps USGS and its partners to track of the storm and its impact on surface water levels. A storm track field is included from NOAA's National Hurricane Center, and real-time USGS streamgage data and Rapid Deployment Gage data are linked through this map-based product.

Storm Surge Sensors are also shown that record fine-resolution storm tide and wave level data. This data became available on the viewer as soon as it was safe to retrieve the sensors and upload the data. In addition, imagery was provided from the National Geodetic Survey.

Following the event, high-water mark (HWM) data was added to the map by field crews soon after collection, including survey data and photos.


The USGS National Map Disaster Coordination Preparedness & Response (DCPR) Map is maintained by the National Geospatial Program. The web map provides geospatial visualization and situational awareness over the current disaster event. In addition to National Map base data and indexes the map can be used as a management and planning resource by providing access to enhanced elevation data availability, NOAA Nexrad weather radar and NOAA NowCoast storm surge and precipitation estimates. The application also provides a visual tool for partner data collected over the event including NOAA and Civil Air Patrol imagery.


For a deeper look into potential coastal change, the USGS Coastal Change Hazards Portal provided forecasts of the probability of coastal erosion during Hurricane Matthew. Also available are lidar-based dune elevations and modelled total water levels at the shoreline, due to both storm surge and wave run-up (provided by the USGS St. Petersburg Coastal and Marine Science Center).


USGS Precipitation Viewer for North Carolina shows recent rainfall data in conjuction with National Weather Service precipitation data.
