Josephine was a short-lived, high latitude tropical storm well out at sea.
a. Synoptic History
Josephine was of non-tropical origin. Surface data indicated
that a weak low pressure system formed along a dissipating, nearly stationary
frontal zone about 750 nautical miles east of Bermuda on 16 September.
Over the next day, as the low moved slowly westward, a small area of deep
convection formed near the low-level circulation center and the system's
cloud pattern changed from one that resembled a non-tropical cyclone to
that of a tropical cyclone. It is estimated that the system became a tropical
depression around 1200 UTC 17 September, while centered about 620 nautical
miles east of Bermuda. The tropical cyclone moved slowly north-northwestward
to northward for about a day. Deep convection associated with the system
was intermittent and at times the low-level center became exposed. However,
the cyclone strengthened slightly and is estimated to have become a tropical
storm by 0600 UTC 18 September. Soon thereafter, Josephine accelerated
northeastward in the flow ahead of a deep-layer mid-latitude trough. The
system lost its tropical characteristics around 1200 UTC 19 September,
at which time a ship report indicated that the cyclone had strengthened
into an storm with winds near 58 mph well removed from the center. Soon
thereafter, the storm merged with a larger extratropical low and frontal
b. Meteorological Statistics
When Josephine became extratropical at 1200 UTC 19 September,
a ship with call sign C6LV3 reported 58 mph winds about 76 nautical miles
southeast of the center.
c. Casualty and Damage Statistics
There were no reports of damages or casualties associated with Josephine.
