Causes and Effects of Hurricane Katrina “Hurricane Katrina was one of the strongest storms to impact the coast of the United States during the last 100 years.” (“Hurricane Katrina” from NOAA) Hurricanes all start in tropical waters because they can only start in warm waters. The wind and air conditions must be just right, and once a hurricane is started it can be moved around by powerful winds. They are basically a very deadly cyclone of wind and water. They range from category 1 to category 5, with 5 being the worst. The most deadly hurricane was on September 8th, 1900 in Galveston, Texas. Hurricane Katrina was the worst storm in the past decade to hit the U.S., and caused lots of damage and got the people mad at their government. 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
