what category was hurricane katrina in new orleans
Hurricane Katrina The storm originated over the Bahamas on August 23 from the interaction between a tropical wave and the remnants of Tropical Depression Ten. Early the following day, the new depression intensified into Tropical Storm Katrina. The cyclone headed generally westward toward Florida and strengthened into a hurricane only two hours before making landfall at Hallandale Beach and Aventura on August 25. After very briefly weakening to a tropical storm, Katrina emerged into the Gulf of Mexico on August 26 and began to rapidly deepen. The storm strengthened to a Category 5 hurricane over the warm waters of the Gulf of Mexico,[3] but weakened before making its second landfall as a Category 3 hurricane on August 29, in southeast Louisiana.
Hurricane Harvey Hurricane Harvey was an extremely destructive Atlantic hurricane which became the first major hurricane[nb 1] to make landfall in the United States since Wilma in 2005, ending a record 12-year span in which no hurricanes made landfall at such an intensity in the country. In a four-day period, many areas received more than 40 inches (100 cm) of rain as the system slowly meandered over eastern Texas and adjacent waters, causing catastrophic flooding. With peak accumulations of 64.58 in (164.0 cm), Harvey was the wettest tropical cyclone on record in the United States. The resulting floods inundated hundreds of thousands of homes, displaced more than 30,000 people, and prompted more than 17,000 rescues. Harvey was the strongest hurricane in the Gulf of Mexico since Rita in 2005. Harvey was also one of three 2017 Atlantic hurricanes to potentially cause at least 50 billion dollars in damages, along with Hurricane Irma in Florida and Maria in Puerto Rico.
