(詳細はhurricane. Local authorities in a predicted hurricane path often recommend or order evacuation of designated flood zones. Some jurisdictions, such as Pinellas County, Florida, use the output from the Sea, Lake, and Overland Surge from Hurricanes (SLOSH) storm surge model developed by the U.S. Federal Emergency Management Agency (FEMA) to create their evacuation zones. These zones loosely correspond to the maximum expected storm surge expected during a category of hurricane. Since these evacuation maps are used by the general public and a more static nature is desirable, some minor averaging or ranging of data is performed before creating the maps. Changes in variables such as mean high-tide, forward speed and direction of the hurricane, and central pressure all affect the output of the SLOSH model. The longer a person has lived in a coastal area, the less likely they are to evacuate. Hurricanes have a longer warning time than most disasters, but details of strength and track are only educated guesses. Official warnings, as with other scenario planning, are based on a worst case, which is not the most probable case. Thus, hurricanes can be predicted to hit a coastal town many times without the town ever actually experiencing the brunt of a storm. When this more probable case happens a number of times, people tend to take evacuation orders less seriously. If evacuation orders are given too early, the hurricane can change course and leave the evacuated area unscathed. People may think they have weathered hurricanes before, when in reality the hurricane didn't hit them directly, giving them false confidence. Those who have lived on the coast for ten or more years are the most resistant to evacuating. () Despite mandatory evacuation orders, many people did not leave New Orleans, United States, as Hurricane Katrina approached. Even after the city was flooded and uninhabitable, some people still refused to leave their homes.〔("New Orleans rescues continue, but some won't go" NPR 9-6-05 )〕〔("Rescuers urge residents to leave New Orleans" NPR 9-6-05 )〕 == Determining if Evacuation is Necessary== Due to the danger of hurricanes, evacuating should always be an option during strong hurricanes. Some residents may believe that due to the monetary cost of evacuation and the price of not being there to care for your home, evacuation is not a good choice. Due to the potential health and safety risks, some areas and people should give evacuating more thought. Hurricane evacuation can be vital to individual safety in some circumstances. You should evacuate if:〔("How Hurricanes Impact You" )〕 * past hurricanes has caused storm surge damage * your home is built on flood plane areas * you live in a mobile home * your home lacks hurricane structural reinforcement 〔("Against the Wind" )〕 * local officials recommend evacuation If you decide not to evacuate, families and individuals should carefully monitor the hurricane updates provided by local the local television and radio crews. The strength of the hurricane may suddenly change based unanticipated converging storm or wind patterns. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hurricane evacuation」の詳細全文を読む スポンサード リンク
