 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 .
