Operationally, the hurricane was not classified due to lack of ship confirmation; by the time it became a hurricane, the strongest winds reported by a ship was 40 mph (65 km/h) about 80 miles (130 km) southeast of the center. Additionally, upon developing a closed eyewall, the cyclone was beginning to interact with the frontal system to its west. However, late on September 3, a ship reported a pressure of 1003 mbar, with a 3-hour tendency increase of 13.5 mb, suggesting a minimum pressure of under 990 mbar. At the time, the storm maintained a T-number of 4.0, resulting in estimated winds of 75 mph (120 km/h) and an estimated pressure of 987 mbar. Maintaining hurricane status for about 18 hours, the storm continued rapidly northeastward and weakened, due to strong wind shear from the approaching cold front. Early on September 5, it is estimated the cyclone became extratropical in the Gulf of Alaska, while located about 315 miles (510 km) southwest of Juneau, Alaska. On the same day, the circulation was rapidly absorbed by the frontal system, and the remnants quickly reached the coast of British Columbia. The remnants of the storm turned southeastward, and was last tracked definitively to a point north of Montana.
