A category 3 hurricane on the Saffir-Simpson scale can produce a storm surge ranging from 9 to 12 feet above normal tide levels. This surge can lead to severe coastal flooding, inundating low-lying areas and causing significant damage to infrastructure, homes, and ecosystems. The impact of such a storm surge can be devastating, particularly in populated coastal regions, leading to evacuation orders and emergency response efforts. The combination of high winds and flooding can result in catastrophic conditions for affected communities.

What factors make a storm surge weaker or stronger?
Storm surge is generally made stronger by several factors:Stronger winds.Larger area covered by strong winds.Longer duration at a higher intensity.Lower barometric pressure, though this is a smaller contributor.High tide, though not a component of storm surge, can add to it in what is called a storm tide.The opposites of these will lead to a small storm surge.Originally storm surge was correlated with wind speed alone, but this was discarded.Examples:In 2004 Hurricane Charley struck Florida as a strong category 4 hurricane. This would normally bring a very large storm surge, but the storm was small and had only recently intensified from a category 2.In 2005 Hurricane Katrina struck the Gulf Coast as a category 3, but due to the storm's enormous size and having recently weakened from a category 5, it had an enormous storm surge.
