A storm surge is a rise in sea level that occurs during a storm, especially hurricanes. When strong winds from the storm push water toward the shore, it can lead to flooding in coastal areas. This surge can be very dangerous, as it can happen quickly and cause significant damage to homes and infrastructure. The height of a storm surge can vary depending on factors like the storm's intensity and the shape of the coastline. For example, areas near New Orleans are particularly vulnerable due to their low elevation and proximity to the Gulf of Mexico. Understanding storm surges is crucial for effective hurricane preparedness and safety.
