What are "hurricane storm surges"?

Hurricane storm surges refer to elevated sea levels that occur as a direct result of hurricanes or tropical storms. When a hurricane approaches land, its strong winds push seawater toward the shore, causing water levels to rise significantly. This phenomenon can lead to flooding in coastal areas and is one of the most dangerous aspects of a hurricane, often resulting in significant damage to property and loss of life.

Understanding storm surges is crucial for coastal safety and disaster preparedness, as these surges can vary greatly in height and impact depending on the storm's intensity, the geography of the coast, and the existing tidal conditions. Recognizing the difference between storm surges and other conditions, such as low tides, storm-free weather, or droughts, is essential for anyone studying coastal Louisiana, where hurricanes are a significant threat.
