اسلاید 6: Public AwarenessIn the early part of this century, coastal residents may have had less than a day to prepare or evacuate their homes from an oncoming hurricane.Today these same locations receive warnings to evacuate from one to two days in advance.Meteorologists and the public rely on hurricane hunters to learn more about the hurricane.They do this by flying aircraft equipped with weather instruments straight into the middle of these powerful storms.Hurricane hunters are operated by both the Air Force Reserve based at Keesler Air Force Base in Mississippi and the National Oceanic and Atmospheric Administration (NOAA).
اسلاید 7: How Are They NamedSince 1953, the Tropical Prediction Center has produced lists of names for hurricanes. As a tropical depression develops into a tropical storm it is given the next available name on the list, which is prepared in alphabetical order and alternates from between male and female names. The list for 2007 is listed below:AndreaBarryChantalDeanErinFelixGabrielleHumbertoIngridJerryKarenLorenzoMelissaNoelOlgaPabloRebekahSebastianTanyaVanWendy

اسلاید 9: Hurricane Katrina hit the U.S. on August 29, 2005. Winds of 140 mph created a 30-foot storm surge. Water breached the dam that protected the city of New Orleans and flooded the low-lying coastlines of Louisiana, Alabama, and Mississippi. With the damage estimated at more than $200 million, and more than one million people forced to leave their homes, Katrina is the most expensive and most destructive natural disaster in U.S. history.
