The National Weather Service (NWS) has developed a technique for forecasting extratropical storm surges along the northeast coast of the United States. The storm surge is caused mainly by the strong winds associated with extra-tropical storms over nearshore areas.

The report contains an adaptation of a unique storm-surge forecasting technique developed by Dr. C.P. Jelesnianski. This technique results in a computed storm surge profile at the inner boundary of an artificial standard basin seaward of the coast. The profile is derived from nomograms based upon a standard storm passing over a standard basin. Thumb rules and guidelines are presented in the publication for subjectively modifying the computer storm surge height as it moves shoreward of the artificial basin boundary, to fit the natural conditions of a particular coastline. Major advantages of this system are its applicability to almost any locale, its adaptability to data normally available to the field forecaster and the speed with which the forecast may be modified to remain current with natural fluctuations of the storm.

"The ESTOFS-Pacific was implemented operationally by NCEP Central Operations (NCO) on the Weather and Climate Operational Supercomputing System (WCOSS) to provide 180-hr forecast guidance of surge combined with tides, astronomical tides, and sub-tidal water levels (the isolated surge) throughout the domain. The ESTOFS provides the National Weather Service (NWS) with a second extratropical surge system in addition to the Extratropical Storm Surge (ETSS) model that currently is based on the Sea Lake and Overland Surge from Hurricanes (SLOSH) model (Jelesnianski et al., 1992). ESTOFS-Pacific fills NWS gaps in operational storm surge and tide modeling coverage in Hawaii. This model serves the needs of local Weather Forecast Offices (WFOs) for coastal marine forecasts. Forecasters will benefit from the gridded astronomic tide predictions that are provided by ESTOFS-Pacific, which can be combined with any gridded surge prediction (generated from model guidance or forecaster). The ESTOFS is also designed to provide the surge with tides to WAVEWATCH III® (WW3) for coupling wave predictions to coastal water levels. ESTOFS uses the same Global Forecast System (GFS) forcing and has the same forecast cycle and length as WW3. Output from ESTOFS-Pacific is disseminated by NCEP's Ocean Prediction Center (OPC) and NWS' Office of Science and Technology/Meteorological Development Laboratory (OST/MDL)"--Page vii.
