On August 23rd 2005 the hurricane started off as a tropical depression, but the next day it became a tropical storm. Its wind speed increased from 75mph, to 80mph, to 90mph, to 125mph in a few days time period. According to an article from NCDC …Katrina reached maximum wind speeds on the morning of Sunday August 28th of over 170mph… It was very powerful and went from a category 1 to category 5 storm in 4 days. Since hurricanes form in warm waters some scientists have another reason for Hurricane Katrina’s power. “Some scientists claim that global warming is partially to blame for the power and endurance of Hurricane Katrina” due to the fact that it’s warming the oceans. They also need continued heat to exist and if the oceans are being heated up the endurance of hurricanes should be longer. So due to wind speed, and partially due to global warming, Hurricane Katrina had a strong impact on the U.S. coast.
New Orleans, Louisiana was the most damaged city after the hurricane. New Orleans suffered from a large number of casualties, a lack of drinkable water, severe property damage, electrical outages and many more difficulties as a result of Hurricane Katrina. Over one million people were evacuated out of their houses, and after all of the devastation most of them had to live in the New Orleans Superdome.
