Why Hurricane Katrina’s storm surge was uniquely destructive
Katrina hurricane In some communities, he pushed the sea in the interior of 10 kilometers.
This water wall turned into a destructive cyclone Generation tragedy Along the northern Gulf coast. As Katrina’s violent winds and unprecedented storm fluctuations, more than 1,300 people died as they changed both coastal lines and communities.
The merger of factors contributed to Katrina’s legacy as one of the worst storms in live memory. But it all started with the hurricane fluctuation of a unique storm.

Katrina was a classic most intense season hurricane
On August 11, a weak discomfort exploding from the African coast would turn into one of the most devastating hurricanes in modern history.

This discomfort turned into a tropical storm on Bahamas on Wednesday, August 24th. Katrina the next day, Miami quickly concentrated on a hurricane because he went ashore in the south of Florida. The system continued to organize while moving to the Gulf of Mexico to the west.
Facing the appropriate conditions and very hot waters, Katrina It was subjected to rapid condensation For two days. This strengthening spell brought a low -grade hurricane to a category of scale category of a low -grade hurricane with a maximum continuous wind of approximately 280 km/h.

Katrina is unique among hurricanes
Tropical systems are not rare on the North Gulf Coast. But Katrina was so close Worst scenario As we see in modern history.
Hurricane Katrina wasn’t just a busy storm – it was a large dimension. At the most intense power, the tropical storm winds of Katrina reached 370 kilometers from the center of the storm, and the hurricane force winds reached 165 kilometers.
Even if the wind speeds of the hurricane weaken before they go ashore, this enormous dimension was essentially cooked in Katrina Destructive storm fluctuations And the waves as they approach the shore.
Katrina forced him to fluctuate a destructive storm on the inside
Storm fluctuation is the sea water that is pushed from the inside with the power of the strong and permanent winds of an storm. The depth and scope of the fluctuation depends on many factors, including the rise and shape of the coastline.
US Gulf Coast Height
Katrina pursued a large coastline areas, which are largely under 10 meters of Louisiana and Southern Mississippi, just above sea level.
This low -lying height, which stretches in a few kilometers at many points, contributed to the severity of the hurricane’s fluctuation flood. The inner form of the coast, local bays and entrances intensified the fluctuation.
Hurricane Katrina Storm Surge Estimates
Southern Mississippi, flooding from the level of 5.0 to 8.5 meters from the level of flood took the burden. The deepest increase occurred along the coast in Mississippi Pass Christian, where experts measured a depth of a maximum height of 8.47 meters from the ground level.
New Orleans, which is devastated by storm fluctuating
The majority of Katrina’s deaths occurred in New Orleans, a few meters below sea level. The city, which is sunk like a bowl between Lake Pontchartrain in the north and the Mississippi River in the south, rely on a complex levees and pumps network to keep water out.
Hurricane Katrina New Orleans Flood Map 2005
Katrina’s powerful winds pushed 4 to 5 meters storm fluctuating to Lake Pontchartrain and Mississippi River and exceeded most of the levees who protected the city.
The water on the routes eroded the soil behind these protective soil structures, and many caused many of them to fail, which allowed the flood waters to rise from broken leves to the low city.
Hurricane Katrina Failed Levee 2005
The water spilled from unsuccessful leves left about 80 percent of New Orleans in the hours after the storm and days.
Considering the damage to levees and infrastructure throughout the city, it took 43 days for the crew to completely clean the flood waters from the affected areas.
