The storm continued inland, passing directly over Ciudad Obregón before dissipating south-southeast of Sierra Vista, Arizona.

The remnants of Pauline triggered showers over the southwest United States and may have been responsible for a damaging tornado which occurred near Glendale, Arizona.

The disturbance was in a large area of convection west of Guatemala in the Gulf of Tehuantepec that began to spread 500 mi (800 km) to the west-northwest on September 26.

[1] After being named, Pauline displayed signs of a tight circulation, but satellite pictures were unable to pick up any distinct features due to nearby cirrus outflow.

[1] Another nearby ship, the Golden Eagle, reported south-southeast winds of 50 mph (80 km/h) and high seas 75 mi (121 km) east of the center.

A United States Air Force reconnaissance plane flew into the hurricane that day and reported that the eyewall was open on the southwest quadrant.

Satellite imagery showed that Pauline had moved over the Gulf of California, the interaction with land having weakened it to a tropical storm.

[1] The Pasadena-based newspaper reported that a tourist in Mazatlán at the time had sent a card saying that the hurricane was responsible for cutting off-shore capers.

[6] In Arizona, Tucson, Phoenix, and Gila Bend all reported rain on October 3 even though Pauline was centered 200 mi (320 km) southeast of Douglas.
