The 'Coastal Emergency Risks Assessment' (CERA) system provides real-time visualization guidance for storm surge and inundation impacts during impending and active tropical storms or severe flooding events. The CERA interactive website is developed at Louisiana State University and extensively used by decision makers, emergency managers, and meteorologists at all levels of government, including NOAA, FEMA, the US Coast Guard, the US Army Corps of Engineers, and state and local operation centers to understand where storm surge extents and water depths are projected to impact. CERA provides high-resolution detail of the projection of storm surge and presents the storm surge modeling forecast results to the end-user in an effective, user-friendly, and visually appealing way.
