The Peak Storm Surge web service graphic depicts the expected storm surge inundation values for the United States Gulf and Atlantic coasts, Puerto Rico, and the U.S. Virgin Islands that are provided in the tropical cyclone public advisory (TCP). These values represent the peak height the water could reach above normally dry ground somewhere within the specified areas. This graphic will be made available on the NHC webpage.

One such valuable asset is the NWS National Viewer’s Tropical Site, which offers a wealth of supplementary information to enhance situational awareness and risk assessment. By integrating these complementary resources, stakeholders can gain a holistic understanding of the potential impacts of tropical cyclones and make more effective decisions to safeguard lives, property, and critical infrastructure.

Update Frequency: Every 6 hours and every 3 hours if the storm is approaching the shore.
