Which factor is the most potentially destructive force in a major hurricane?

• A. Storm surge
• B. Wind shear
• C. Tornadoes
• D. Heavy rain

Answer: (A)

Storm surge is the most dangerous factor in a major hurricane because the coastal flooding it produces tends to cause the largest and most widespread destruction. As the storm’s onshore winds push a massive column of seawater ahead of landfall, water levels rise well above normal tides, overwhelming dunes, levees, and barriers and sweeping inland. This flooding wrecks buildings, roadways, and critical infrastructure, and it often results in the highest loss of life and property damage in hurricane events. Wind can damage structures and heavy rain can cause inland flooding, but those hazards are typically more localized or occur after surge has already inundated areas. Tornadoes inside hurricanes contribute additional local damage but are relatively rare and limited in extent. So, the surge stands out as the most potentially destructive force the hurricane brings.
