This is a visualization of the ADCIRC Surge Guidance System (ASGS) output for Hurricane Joaquin (2015), advisory number 12, when the storm was considered a potential threat to the North Carolina coast. This ASGS model grid has very high resolution in the North Carolina area, and runs on RENCI high-performance computing systems. Different instances of the forecast system focus on different parts of the US and Gulf of Mexico coasts. The colors show water levels (in feet), with darker reds and oranges depicting higher water levels. The storm's forecast track is also shown, along with the cone of track uncertainty. The simulation is forced by surface winds and atmospheric pressure derived from the National Hurricane Center's consensus forecast track, and the model output is posted to the Nc-Cera.Renci.Org website for dissemination.
