NGOMSSC delivers surge guidance via existing relationships and distribution channels, enabling

  • utreach to those most affected by

coastal hazards NGOMSSC, through its relationship with the project, provides up to date information on surge guidance methodology and advances in the state of the art to its end users Accurate, local surge forecasts enable NGOMSSC and NWFWMD personnel to secure assets prior to event and guide assessment efforts after NWFWMD enhances its role as a Cooperating Technical Partner and continues to serve as a model for productive Federal, Local and University partnerships NWFWMD obtains realistic surge scenarios to conduct table-top response exercises Coastal hazards community (DHS, NOAA, Local Government, and University partners) receive talented and trained personnel via SUMREX and other cooperative programs and events between the Research and Education PIs
