1984 Atlantic hurricane season
The 1984 Atlantic hurricane season officially began on June 1, 1984, and lasted until November 30, 1984. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The 1984 season was an active one in terms of named storms, but most of them...

. It quickly organized, and gained tropical characteristics as it strengthened into a tropical storm on October 8. Gradual intensification occurred thereafter, reaching hurricane status on October 10. The storm headed northward, remaining well offshore of the eastern United States. Josephine strengthened further and peaked as a moderately strong Category 2 hurricane on the Saffir-Simpson Hurricane Scale

Although Josephine remained well offshore of the eastern United States, the effects from the storm and an area of high pressure produced strong winds and high seas along the coast. In North Carolina, high tides caused severe beach erosion

 on October 7. Upon formation, the system consisted of a very broad subtropical low, as well as a poorly-defined surface circulation. As the subtropical depression drifted westward, it became further organized. By midday on October 8, an Air Force reconnaissance aircraft flight indicated that the subtropical depression intensified and acquired enough tropical characteristics to be considered a tropical storm.

 named the storm Josephine.

Further intensification was slow, as Josephine was very large and existed in a relatively cool environment. Shortly thereafter, Josephine curved northward to the northeast of the Bahamas. By October 10, Josephine had strengthened into a hurricane. Josephine continued north-northeastward, and became a Category 2 hurricane on October 11. Winds increased slightly, and Josephine reached its maximum sustained wind

s of 105 mph (165 km/h) on October 12. Josephine weakened back to a Category 1 hurricane on October 13. That day, an area of high pressure moved off the northeastern United States, which caused Josephine to decelerate and abruptly curve northeastward, and eventually southeastward. By October 15, Josephine began to accelerate east-northeastward. Later that day, Josephine reached its minimum barometric pressure of 965 mbar (28.5 inHg).

As Josephine continued east-northeastward, it had weakened back into a tropical storm. Under the influence of an area of high pressure to the north and a nearby area of low pressure, Josephine began executing a cyclonic loop to the north while approaching Atlantic Canada. During the cyclonic loop, it transitioned into an extratropical cyclone on October 18. Shortly thereafter, the remnants of Josephine merged with a broad mid-latitude trough. The remnants of Josephine tracked southward and completed the cyclonic loop on October 19. The system eventually curved to the east-northeastward and moved in that direction until it became unidentifiable on October 21.

, tides were 5.8 ft (1.8 m) above the mean sea level. In addition, wave heights of 8 to 12 ft (2.4 to 3.7 m) were reported on the island.
