Final report
The Hurricane Katrina Event November 10th-12th, 2022 On August 23rd of 2005, a damaging storm began which would later turn into one of the most horrific Hurricanes. Hurricane Katrina made its landfall between Miami and Fort Lauderdale as a category one Hurricane. Category one Hurricanes have wind speeds from 75mph-95 mph that can produce some damage like large branches snapping off of trees and could possibly damage roofs, shingles, and gutters. As the Hurricane escalated to a category five with the winds reaching 170 mph and became one of the strongest Hurricanes to exist in the Atlantic ocean. The hurricane hit Louisiana and moved its way to Mississippi. Due to the hurricane being a category four it devastated many homes and resorts along the coast. Category five hurricanes are considered major hurricanes that can cause extensive damage. Homes that are well built can have catastrophic damage such as loss of a roof, exterior walls, and power outages. These hurricanes can cause trees and power poles to fall and damage property or close roadblocks making it hard for anyone to get on the street or off of it. Properties reached by category four hurricanes and damaged by one can cause the area to be unlivable for weeks or even months. For a hurricane to be classified as a category five hurricane it must have wind speeds of at least 157 mph and a storm surge. The wind speeds can be deadly so if you ever
encounter a hurricane of any sort follow any instructions given. A storm's storm surge is a sudden drop in water level that is higher than the expected tide. The storm's wind circulation creates a vertical circulation by blowing on the ocean. The circulation is unaffected while the storm is in deep water. Although, when the storm approaches land and shallower water, this upward course gets disturbed because it can't return down, so it has no place to go except for up and over the land. The following diagram down below shows a storm surge.

This next graphic shows just some of the damage hurricane Katrina caused. As you can see in the picture below cars are submerged under water and and streets are undriveable due to them being flooded. The houses in the pictures have extensive damage as well as water damage due to hurricane Katrina.

Hurricane Katrina first formed August 23rd of 2005 Near the Bahamas and passed over Miami as a category one hurricane then traveled to Louisiana at 4 a.m. on August 23rd. The route Katrina took to take control of the Loop Current, which provided deep, warm water, was one factor in the storm's rapid development. This storm left many people and cities without shelter, food/water, and electricity leaving people to hope help was coming. Many states were impacted by Katrina including Alabama, Louisiana, and Mississippi, and the city of New Orleans. This hurricane caused 1,833 fatalities due to hurricanes high wind speeds and people left without the essentials to survive. The diagram below will show where the hurricane hit the worst.

The image below is a satellite picture that NASA captured of the hurricane and it shows where the hurricane hit the worst and also just shows how huge this hurricane really was. What made hurricane katrina different from other hurricanes is the tension estimation made Katrina the fifth most extreme Atlantic tropical storm on record at that point, just to be outperformed by hurricane Rita and Wilma later in the season; Prior to Rita's breaking of the record, it was also the strongest hurricane ever recorded in the Gulf of Mexico.
The storm was the most expensive national disaster in our nation's history because it flattened entire communities, killed 1,833 people, displaced more than a million others, and caused more than $100 billion in damage.
