The most significant impact from Typhoon Hester was felt in South Vietnam, where winds in excess of 155 km/h (95 mph) caused extensive damage to several United States Army bases.

Newspaper reports indicated that 100 Vietnamese lost their lives due to the storm, including 33 following a plane crash near Quy Nhơn.

In the wake of the storm, the South Vietnamese government provided the hardest hit areas with relief funds and supplies.

[1] Due to the cyclone's proximity to the country, the Philippine Atmospheric, Geophysical and Astronomical Services Administration also monitored the storm and assigned it with the local name Goying.

The Joint Typhoon Warning Center estimated peak winds to have reached 165 km/h (105 mph) along with a central pressure of 967 mb (hPa; 28.56 inHg).

Making landfall directly over the United States military installation in Chu Lai, Hester damaged or destroyed 75 percent of the structures in the base.

[7] Heavy rains accompanying the storm, peaking at 5.44 in (138 mm) at Camp Eagle, caused considerable flooding in the country.

[1] Flooding from the storm washed out a bridge between Fire Support Base Birmingham and Camp Eagle, temporarily isolating two units within the 94th Field Artillery Regiment.

[1] According to government officials, the entire banana, rice, and sugar cane crop was destroyed and harvests could not be made until the following spring.

[1][5] On October 25, Premier Tran Thien Khiem toured some of the storm-ravaged areas and made on-the-spot grants of $19,000 to each province and $3,500 to Đà Nẵng.

Later that day, President Nguyen Van Thieu ordered $725,000 be made available for disaster relief in the northern provinces following an emergency meeting.
