The Coastal Emergency Risks Assessment (CERA) group delivers storm surge and wave predictions for impending or active tropical cyclones in the United States. Based on the Advanced Circulation and Storm Surge model (ADCIRC), the CERA web mapping application provides an easy-to-use interactive web interface.
Emergency managers, weather forecasters, and GIS specialists can retrieve real-time forecasting results to evaluate the impacts of a tropical event or to see the tide, wind-wave, and extra-tropical surge conditions on a daily basis.
The CERA tool was created at Louisiana State University in collaboration with Louisiana’s Sea Grant and the Department of Homeland Security Coastal Resilience Center of Excellence housed at the University of North Carolina at Chapel Hill. The information shown on the CERA websites is produced by a system that generates real-time surge and wave guidance based on two models: ADCIRC for surge and Simulating Waves Nearshore (SWAN) for waves.
The CERA maps are produced, solely, to provide guidance to local, state & federal emergency managers and designated emergency responders. By accessing the CERA maps and using the associated GIS data, you agree to the CERA Terms & Conditions.
