Tropical Storm Julian (2039)

Tropical Storm Julian was a short-lived but very unusual tropical cyclone that formed in the Gulf of Lawrence in mid-September of 2039. The tenth named storm of the 2039 Atlantic hurricane season, Julian formed from an extratropical low that had trekked across the North American continent over the past week. It never managed to strengthen much because of its unusual formation area, where waters were relatively cool. Julian later dissipated on September 19 after becoming a remnant low.

Because of its short-lived existence, Julian only caused $5 million in damages in Canada, and as such, the name was not retired.

Meteorological history
In mid-September, an extratropical cyclone formed near the southern portions of Canada. The storm continued eastward, bringing gusty winds to portions of the northern tier of the United States. By September 14, the cyclone had begun to show an occluded front and hints of separating from its fronts. The National Hurricane Center (NHC) began monitoring the system for possible subtropical development, stating that "[it] is showing some signs of tropical development in a very unusual location, a place where no tropical cyclone has actually formed before". The extratropical cyclone began to slow down and show improvement in structure as it moved into Canada and approached the Gulf of Lawrence.

By late on September 15, the cyclone had moved into the Gulf of Lawrence, where it continued to show increasing signs of separating from its fronts as well as the wind field contracting and becoming more symmetric, as shown by surface observations, not to mention convection was becoming more concentrated near the Center. Based on continued improvement, the National Hurricane Center initiated advisories on Tropical Depression Ten at 12:00 UTC on September 16 while over the Gulf of Lawrence. The depression later strengthened into a tropical storm 12 hours later, earning the name Julian, while also peaking in intensity, as convection fired its closest to the center. Shortly afterwards, the satellite appearance of Julian began to degrade as it turned northwards, mainly due to moderate to high wind shear and cool sea surface temperatures. In addition, the cyclone was already beginning to show signs of transitioning back to an extratropical cyclone. By 06:00 UTC on September 17, Julian made landfall as a minimal tropical storm before weakening to a tropical depression, becoming a remnant low shortly afterwards. extratropical shortly after. The remnants of Julian began to accelerate northwards before being absorbed by a larger extratropical low the next day.

Impact
Although Julian affected areas such as Nova Scotia and Newfoundland, damage was relatively minimal, with total damage costs coming out to $5 million (2039 USD).
