The 1998 Atlantic hurricane season was an average Atlantic hurricane season in which twelve named storms formed. Although Tropical Storm Alex formed on July 27, the season officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The final storm, Hurricane Nicole, lasted until December 1, one day after the official end of the season. The season produced fourteen tropical depressions, all of which intensified into tropical storms, ten became hurricanes, and three became major hurricanes. The two most significant storms of the season, in terms of loss of life and damage, were hurricanes Georges and Mitch. The former traveled across much of the Greater and Lesser Antilles and made landfall in Mississippi as a Category 2 hurricane. Resulting in extensive damage and a large number of fatalities.〔 Hurricane Mitch's slow movement over Central America caused catastrophic flooding, making it the second deadliest Atlantic tropical cyclone on record.〔 This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. ==Timeline of events== ImageSize = width:800 height:200 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/07/1998 till:31/12/1998 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/07/1998 Colors = id:canvas value:gray(0.88) id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression_=_<39_mph_(0-62_km/h) id:TS value:rgb(0,0.98,0.96) legend:Tropical_Storm_=_39-73_mph_(63-117 km/h) id:C1 value:rgb(1,1,0.80) legend:Category_1_=_74-95_mph_(118-153_km/h) id:C2 value:rgb(1,0.91,0.46) legend:Category_2_=_96-110_mph_(154-177_km/h) id:C3 value:rgb(1,0.76,0.25) legend:Category_3_=_111-130_mph_(178-209-km/h) id:C4 value:rgb(1,0.56,0.13) legend:Category_4_=_131-155_mph_(210-249_km/h) id:C5 value:rgb(1,0.38,0.38) legend:Category_5_=_>=156_mph_(>=250_km/h) Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:10 align:left fontsize:S shift:(4,-4) anchor:till from:27/07/1998 till:02/08/1998 color:TS text:"Alex (TS)" from:19/08/1998 till:30/08/1998 color:C3 text:"Bonnie (C3)" from:21/08/1998 till:24/08/1998 color:TS text:"Charley (TS)" from:24/08/1998 till:03/09/1998 color:C2 text:"Danielle (C2)" from:31/08/1998 till:03/09/1998 color:C2 text:"Earl (C2)" from:08/09/1998 till:13/09/1998 color:TS text:"Frances (TS)" from:15/09/1998 till:01/10/1998 color:C4 text:"Georges (C4)" barset:break from:17/09/1998 till:20/09/1998 color:TS text:"Hermine (TS)" from:19/09/1998 till:27/09/1998 color:C1 text:"Ivan (C1)" from:21/09/1998 till:01/10/1998 color:C2 text:"Jeanne (C2)" from:23/09/1998 till:28/09/1998 color:C2 text:"Karl (C2)" from:05/10/1998 till:09/10/1998 color:C1 text:"Lisa (C1)" from:22/10/1998 till:01/11/1998 color:C5 text: barset:break barset:skip barset:skip barset:skip barset:skip barset:skip from:03/11/1998 till:05/11/1998 color:TS text:"Mitch (C5)" from:24/11/1998 till:01/12/1998 color:C1 text:"Nicole (C1)" barset:break bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/07/1998 till:01/08/1998 text:July from:01/08/1998 till:01/09/1998 text:August from:01/09/1998 till:01/10/1998 text:September from:01/10/1998 till:01/11/1998 text:October from:01/11/1998 till:01/12/1998 text:November from:01/12/1998 till:31/12/1998 text:December TextData = pos:(570,30) text:"(From the" pos:(618,30) text:"Saffir-Simpson Hurricane Scale)" 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「Timeline of the 1998 Atlantic hurricane season」の詳細全文を読む スポンサード リンク
