Under the Coastal Storm Program (CSP), the National Weather Service (NWS) is collaborating with NOAA's National Ocean Service (NOS) to couple inland flood and coastal estuary modeling. The CSP will improve the accuracy of marine wind speed, wave height, and estuary water level forecasts which are necessary to improve the prediction of inland flooding in coastal areas. Lessons learned during this demonstration will be applied in other similar areas along the East and Gulf coasts.

In support of the newly developed CSP demonstration which began in 2005, seven forecast-supporting hydrologic locations along the St. Johns River in northeast Florida have been added.

Currently, the NWS is generating water level forecasts for the St. Johns River. NOS estuary model generates salinity forecasts and the maps are also being generated and displayed as part of this experimental project.
