A tropical wave emerged into the Atlantic Ocean from the west coast on September 1.
Due to entrainment of dry air, the wave struggled to maintain convection as it progressed westwards.
The National Hurricane Center (NHC) did not begin monitoring the system in its Tropical Weather Outlooks until a concentrated area of low pressure developed about 350 mi (560 km) east of the Leeward Islands on September 8.
The convection quickly diminished and mainly consisted of only sporadically bursts of shower and thunderstorm activity.
Little change in organization took place as the disturbance tracked through the Bahamas on September 11 and September 12.
However, the disturbance quickly organized and developed more thunderstorm activity while approaching Florida.
A tropical depression is estimated to have formed at 06:00 UTC on September 13, around the time it was making landfall in Jensen Beach, Florida.
Within a few hours, a strong band of deep convection formed in the northeast quadrant of the cyclone, though westerly wind shear prevented any significant convection from developing on the western side of the storm.

Radar and surface observations indicate that the depression intensified into Tropical Storm Julia around 12:00 UTC on September 13, about six hours after forming, becoming the first tropical cyclone to intensify into a tropical storm while over land.
Once designated as a tropical storm, Julia reached its peak intensity of 50 mph (85 km/h) while inland, At 03:00 UTC on September 14, the NHC initiated advisories on Julia – which was then centered near Jacksonville – and initially predicted that the storm would move north-northwestward and become extratropical or a remnant low pressure area over Georgia by September 16.
Shortly thereafter, Julia weakened slightly due to moderate to high wind shear.
Periodic bursts of convection occurred near the center of the system as it moved over water and paralleled the coast of Florida and Georgia.
However, these bursts were short-lived due to strong wind shear, causing its elongated circulation to become far removed from the deep convection.
Operationally, the NHC erroneously downgraded Julia to a tropical depression on September 15.
At 00:00 UTC that day, Julia attained its minimum barometric pressure of 1007 mbar (29.7 inHg).

Julia consisted of mainly a low-level swirl of clouds by late on September 16; however, minimal convection kept the storm at the minimum requirements for a tropical cyclone.
Early on September 17, Julia weakened to a tropical depression.
Despite a slight increase in convection and organization, wind shear and dry air continued to take its toll on the increasingly ill-defined storm, and Julia degenerated into a remnant low by early on September 19 after being devoid of convection for nearly 12 hours.
While moving north, the remnants of Julia then transitioned into a weak extratropical cyclone and made a small westward turn before dissipating inland over North Carolina on September 21.
