The 1948 Atlantic hurricane season featured the first tropical cyclone before the month of June since 1940. The season officially began on June 15, 1948, and lasted until November 15, 1948. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. There were 10 tropical cyclones; six storms attained hurricane status, and four storms intensified into major hurricanes, which are Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale.〔 Operationally, it was believed that a weak tropical disturbance formed over the southeast Bahamas in May and moved northwest into the Georgia coast near Savannah. This system was later excluded from HURDAT. The seventh tropical cyclone was not operationally considered a tropical cyclone, but was later added to HURDAT. The sixth and eighth systems, designated as Dog and Easy by the Air Weather Service in real time, respectively, were the most intense tropical cyclones of the season, peaking as a Category 4 hurricane with a minimum barometric pressure of . The former caused eight deaths and $400,000 (1948 USD) in damage after bring strong winds, rough seas, and heavy rainfall to Bermuda and Atlantic Canada. In Cuba and Florida, the eighth hurricane left 13 fatalities and at least $14 million in damage. The ninth hurricane, assigned the name Fox by the Air Weather Service, brought similar impact to Cuba and Florida about two weeks later. In May, the first tropical cyclone killed 80 people from flooding in the Dominican Republic. Collectively, the storms of this season left around $28.8 million in damage and 106 fatalities. ==Season summary== 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:01/05/1948 till:01/12/1948 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/05/1948 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression_=_<39_mph_(0–62_km/h)_(TD) id:TS value:rgb(0,0.98,0.96) legend:Tropical_Storm_=_39–73_mph_(63–117 km/h)_(TS) id:C1 value:rgb(1,1,0.80) legend:Category_1_=_74–95_mph_(119–153_km/h)_(C1) id:C2 value:rgb(1,0.91,0.46) legend:Category_2_=_96–110_mph_(154–177_km/h)_(C2) id:C3 value:rgb(1,0.76,0.25) legend:Category_3_=_111–130_mph_(178–209-km/h)_(C3) id:C4 value:rgb(1,0.56,0.13) legend:Category_4_=_131–155_mph_(210–249_km/h)_(C4) id:C5 value:rgb(1,0.38,0.38) legend:Category_5_=_>=156_mph_(>=250_km/h)_(C5) Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:10 align:left fontsize:S shift:(4,-4) anchor:till from:22/05/1948 till:29/05/1948 color:TS text:"One (TS)" from:07/07/1948 till:11/07/1948 color:TS text:"Two (TS)" from:26/08/1948 till:05/09/1948 color:C3 text:"Able (C3)" from:30/08/1948 till:01/09/1948 color:TS text:"Baker (TS)" from:01/09/1948 till:06/09/1948 color:C1 text:"Charlie (C1)" from:04/09/1948 till:15/09/1948 color:C4 text:"Dog (C4)" from:07/09/1948 till:10/09/1948 color:TS text:"Seven (TS)" barset:break from:18/09/1948 till:24/09/1948 color:C4 text:"Easy (C4)" from:03/10/1948 till:16/10/1948 color:C3 text:"Fox (C3)" from:08/11/1948 till:11/11/1948 color:C1 text:"George (C1)" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/05/1948 till:01/06/1948 text:May from:01/06/1948 till:01/07/1948 text:June from:01/07/1948 till:01/08/1948 text:July from:01/08/1948 till:01/09/1948 text:August from:01/09/1948 till:01/10/1948 text:September from:01/10/1948 till:01/11/1948 text:October from:01/11/1948 till:01/12/1948 text:November TextData = pos:(570,30) text:"(From the" pos:(617,30) text:"Saffir-Simpson Hurricane Scale)" The 1948 Atlantic hurricane season was slightly below average, and it featured a total of nine storms, which fell below the climatological seasonal average of ten. All of the hurricanes formed during the latter half of the season, and the number of intense hurricanes surpassed the average of two. The season featured one tropical storm in May, and it was among 18 tropical systems that formed in the month of May in the Atlantic basin. Of the 10 tropical disturbances detected operationally, five struck the United States with winds of or greater, while the other tropical systems affected islands, remained over the open ocean, or affected the country with winds below tropical storm intensity. Three hurricanes made landfall in the United States, while the three other storms with winds of at least largely remained at sea. Collectively, the storms of this season left around $28.8 million in damage and 106 fatalities.〔 * * * * * 〕 The strongest storms of the season attained Category 4 intensity; two of the major hurricanes formed in the western Caribbean Sea and affected the United States in late September and October. A minimal hurricane struck southern Louisiana, causing tides of five feet and winds of in New Orleans. A minimal tropical storm made landfall near Destin in July. An intense hurricane attained Category 4 strength and produced extensive damage and wind gusts on Bermuda in mid-September. A Category 4 hurricane struck the Florida Keys and the Everglades, resulting in $12 million of damages in the state. After the passage of one week, another hurricane affected the region as a Category 2 storm, after crossing Cuba with winds of . Only three direct fatalities occurred in the United States, largely because of improved evacuations and adherence to warnings and advisories. The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 106. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. It is only calculated for full advisories on tropical systems at or exceeding 39 mph (63 km/h), which is tropical storm strength. 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「1948 Atlantic hurricane season」の詳細全文を読む スポンサード リンク
