Continuing westward through the Formosa Strait, the storm made its final landfall in southern China on July 30 and dissipated inland two days later.

After passing near Taiwan, Andy brought strong winds, which resulted in thirteen deaths, and two others were rendered missing.

Late on July 21, a Tropical Cyclone Formation Alert (TCFA) was issued for the middle system following a drop in barometric pressure and an increase in organization.

[3][nb 2] During the evening hours of July 22, Hurricane Hunters found winds of 65 to 70 km/h (40 to 45 mph) and a minimum pressure of 995 mbar (29.4 inHg).

Based on this, the Joint Typhoon Warning Center (JTWC) classified the system as a tropical storm and named it Andy.

While passing around 160 km (100 mi) south of Guam,[1] the JMA upped Andy into a severe tropical storm.

After briefly leveling off in intensity, Andy continued to gain strength, and during the morning hours of July 26, the JMA reported winds of 170 km/h (105 mph).

[1] However, on July 29, the JMA lowered the intensity of the cyclone to 145 km/h (90 mph)[3] as the storm's eye disappeared on satellite imagery.

Despite briefly emerging into the Formosa Strait,[1] the JMA downgraded Andy into a severe tropical storm just before landfall in Southern China.

[7] While affecting Taiwan, Typhoon Andy snapped trees and toppled billboards,[8] in addition to generating high waves.

Along the southern portion of the island, 300 power poles were downed, making damage reports difficult for the United Press International to obtain.

[11] Eight people were killed in storm-related accidents, including a man and a woman who died when a car flipped in the central portion of the country.

[8] Furthermore, four members of a fishing party were swept out to sea and drowned and an elderly man was blown off a roof as he tried to fix leaks in it.

Tate's Cairn observed 205.3 mm (8.08 in) of rain during the passage of the storm, the highest in the vicinity of Hong Kong.
