Hurricane Katrina By Gabrielle Izu
Hurricanes are a natural disaster formed near the equator, due to it's just right warmth and air pressure. A hurricane forms when air near the ocean's surface becomes warm and rises up, causing a lower air pressure area. Areas with higher pressure around this low pressure area will push into this low pressure area, but this air will also heat up, eventually rising too. As this cycle continues clouds are forming were the warm air cools off. Eventually these clouds will begin to expand and start to spin, becoming a Tropical Storm that might turn into a hurricane.
Hurricane Katrina formed in the Bahamas on August 23, 2005, and meteorologists were able to warn the public about her. On August 25, 2005 Hurricane Katrina made landfall in Florida as a Category 1 Hurricane. Only two people died, so people dismissed it as a regular hurricane passing through, but little did they know what catastrophe was going to hit Louisiana along with Alabama and Mississippi.
After she made her first landfall she went back into the Gulf of Mexico, stalling under a cyclone until she became a Category 5 and headed for Louisiana on August 28. She extended 400 miles across and had winds up to 100-140 miles per hour. The authorities called for a mandatory evacuation, but due to traffic and not having cars some people were stuck in New Orleans. Most either decided to stay at the Superdome or wait the hurricane out at home.
Then Katrina hit. The levees failed and the water either destroyed or flooded through them. New Orleans was under sea level so nobody was prepared for the damage. Homes were decimated, ecosystems torn apart, and thousands were dead. For many months the people in New Orleans were stuck, due to all of the flooding most of the roads were closed. Places like 9th ward and St Bernard Parish were under so much water people had to take cover in the attics and rooftops. The government was not responding and the people were getting desperate.
Above are just a few shots of the physical damage of Katrina. Due to the levee failure flood waters swept away many buildings, trees, and plants. Katrina also spread raw sewage and toxic chemicals around, harming the ecosystem. All of these are horrible outcomes of Hurricane Katrina, but one of the most prominent has to do with the wetlands.
