During the 2010 Atlantic hurricane season, the Coastal and Inland FLooding Observation and Warning (CI-FLOW) project successfully produced real-time predictions of total water level, its individual components (river flow, tides, waves), and maximum inundation levels for eastern North Carolina, the Pamlico Sound, and the near-shore Atlantic Ocean for hurricane Earl and Tropical Storm Nicole.

Real-time predictions were accomplished by connecting a distributed hydrologic model (NWS HL-RDHM), forced with high-resolution QPE/QPF, to a hydrodynamic model (ADCIRC + SWAN), forced with river discharge, tidal elevations, and atmospheric and wave boundary conditions. Based on feedback from NWS forecasters and coastal stakeholders, CI-FLOW implemented upgrades to its computing architecture, models, and visualization systems prior to the 2011 Atlantic hurricane season.

This presentation will provide an overview of the upgraded real-time system, system specifications, and examples of the data suite and decision-support tools currently available in real-time from CI-FLOW visualization portals.
