Description:
Hurricane Katrina pushed ashore a massive storm surge of up to about 9 meters (30 feet), with the highest recorded surge reaching 9.6 meters (31.7 feet) in Waveland, Mississippi. This makes the correct choice from your options 8m, since it best matches the documented surge range.
🌊 Storm Surge Details
Peak surge height: 9.6 meters (31.7 feet) in Waveland, Mississippi.
General surge range: 5.5–9 meters (16–30 feet) along the Mississippi barrier islands.
Comparison to Hurricane Camille: Katrina’s surge exceeded Camille’s by more than 4 feet, setting a Gulf Coast record.
Impact on New Orleans: Levee failures compounded the surge, flooding 80% of the city.

🌍 Contextual Impact
Mississippi Coast: Entire towns like Bay St. Louis and Waveland were obliterated by the surge.
Barrier Islands: Ship Island and Horn Island saw surges overtopping historic structures like Fort Massachusetts.
Infrastructure Damage: Surge wiped out bridges, roads, and coastal defenses, amplifying Katrina’s $81 billion damage toll.
⚠️ Why Surge Matters
Storm surge is often deadlier than wind in hurricanes. Katrina’s surge demonstrated how low-lying coastal areas are extremely vulnerable, especially when protective levees fail. This is why surge forecasting and evacuation planning remain critical in hurricane-prone regions.
