Early on July 2, Chaba attained typhoon status and made landfall in Guangdong a few hours later.

Chaba dropped below typhoon status shortly after landfall, and weakened to a tropical depression on the next day and turned to the northeast.

The extratropical renmants of Chaba continued to move northeastward, emerged into Bohai Sea on July 6 and dissipated just off the Korean Peninsula on the next day.

Chaba later sank a crane vessel Fu Jing 001 offshore Yangjiang, and caused 25 dead with 1 missing.

2 people were killed in Hainan, another person was missing in Guangxi, and the total damage amounted to ¥3.12 billion (US$466 million).

On June 28, the Japan Meteorological Agency (JMA) began monitoring a low-pressure area over the South China Sea.

[2] The same day, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) followed suit and assigned the local name Caloy.

[3] The following day, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA) to the system.

[9] Chaba gradually intensified while moving north-northwestward under warm sea surface temperature of 30 °C (86 °F) and low to moderate wind shear.

[10] Chaba intensified further to a severe tropical storm later that day while located to the northeast of the Paracel Islands.

[11] On July 1, Chaba steered by a subtropical ridge over the northern Philippines and turned northwestward while continued to intensity under favourable condition.

[14] According to the JTWC, Chaba attained peak 1-minute sustained winds of 85 mph (140 km/h) at 03:00 UTC July 2, equivalent to a Category 1 on the Saffir–Simpson scale.

[15] Three hours later, the JMA reported that Chaba attained peak intensity with 10-minute sustained winds of 80 mph (130 km/h) and a barometric pressure of 965 hPa (28.50 inHg).

[16] Maintaining its peak intensity, Chaba made landfall in Maoming, Guangdong at 15:00 CST (07:00 UTC).

[17] Weakening took place immediately after landfall due to land interaction, the JMA soon downgraded Chaba to a severe tropical storm.

The extratropical remnants of Chaba continued to move northeastward, emerged into the Bohai Sea on the following day, and dissipated on July 7 while located just off the coast of North Korea.

[22] Although Chaba did not directly impacted the country, it enhanced the southwest monsoon (known locally as habagat) and brought rainfall to Luzon and Western Visayas.

[24] In Hainan, the provincial meteorological service issued a Level III emergency response to floods and typhoon on July 1, and warned that heavy rains could slash the island.

[29] In Guangdong, the provincial meteorological service issued a Level IV emergency response to floods and typhoon on June 30.

[36] Despite weakened significantly before moving into Hunan, Chaba still brought heavy rainfall and caused flooding to the province.

About 109,010 ha (269,400 acres) of crops were destroyed, and the total damage across the country amounted to ¥3.12 billion (US$466 million).

[39] On July 2, a crane vessel Fu Jing 001 broke into two parts and sank at about 190 mi (300 km) southwest of Hong Kong due to adverse weather brought by Chaba.
