Hurricane Arthur - June 26 - July 5, 2014
A convective system moving across the northwest Gulf of Mexico sent a mid-
level shortwave through the southeast United States.
As the shortwave interacted with a frontal zone across the Carolinas, a
surface low formed on June 27. The low moved southeast
into the Atlantic, though its convection was minimal towards the end of
June. On June 30, the low had a well-defined circulation.
Late in the day, convection became better organized and the system became
a tropical depression that night. Development continued,
with Arthur becoming a tropical storm during the morning of July 1 while
looping offshore Florida. On July 2, Arthur moved north
in the direction of the Carolinas. Hurricane status was acheived early
on July 3. Arthur turned north-northeast as an upper-level
trough deepened across the East. Becoming a category two hurricane,
Arthur moved ashore eastern North Carolina late on July 4
with a well-defined eye. The cyclone weakened after moving back into the
Atlantic, with its eye becoming obscured on July 5 while
moving south of New England. Vertical wind shear became an increasing
issue, with Arthur evolving into an extratropical low on
