Understanding Coastal Flooding and Storm Surge - National Weather Service
What is coastal flooding/storm surge? Storm Surge is an abnormal rise of water generated by a storm, over and above the predicted astronomical tide. Storm Tide is the water level produced during a storm due to the combination of storm surge and the astronomical tide.

Severe Weather 101: Flood Types - NOAA National Severe Storms Laboratory
Extreme flooding can occur in coastal areas particularly when storm surge coincides with normal high tide, resulting in storm tides reaching up to 20 feet or more in some cases. Along the coast, storm surge is often the greatest threat to life and property from a hurricane.
Climate Change Indicators: Coastal Flooding | US EPA
Sep 6, 2024 · As relative sea level rises due to climate change (see the Sea Level indicator), one of the most noticeable consequences is an increase in coastal flooding. Flooding typically occurs during seasonal high tides (“king tides”) and storms that push water toward the shore.
Sea Level Rise and Coastal Flooding Impacts - National Oceanic …
Sea Level Rise Viewer: Visualize community-level impacts from coastal flooding or sea level rise (up to 10 feet above average high tides) at U.S. coastal locations.
What is high tide flooding? - NOAA's National Ocean Service
High tide flooding falls into three levels of severity: minor, moderate, and major. The classifications measure how much water levels exceed average high tide for that location. Minor high tide flooding is when water levels reach 0.55 meters (1.8 feet) above average high tide.
Flooding typically occurs during seasonal high tides (“king tides”) and storms that push water toward the shore. In recent years, however, coastal cities are increasingly flooding on days with less extreme tides or little wind, even on sunny days.
