The colour represents the storm's maximum sustained wind speeds as classified in the Saffir–Simpson scale (see below), and the shape of the data points represent the nature of the storm, according to the legend below.

context_page_description: Tropical Storm Bebinca was a weak but erratic and long-lived tropical cyclone that affected South China and Vietnam in mid-August 2018. Bebinca originated from a tropical depression over the South China Sea on August 9. Maintaining this intensity for a few days near the Guangdong coast, the system intensified into a tropical storm south of Jiangmen on August 13. The storm moved slowly to the east and then curved back on the next day, before making landfall in the Leizhou Peninsula on August 15. Bebinca crossed the Gulf of Tonkin and made landfall in Vietnam on August 16, before dissipated on the next day.
  In China, 6 people were dead and the economic losses by the storm reached ¥2.31 billion. In Vietnam, Bebinca killed 13 people. Moderate damage to agriculture and infrastructure were reported in Northern Vietnam, with heavy rains caused multiple landslides and blocked the road. Total damage in Vietnam were over ₫1.34 trillion.
context_section_description: Late on August 9, the Japan Meteorological Agency (JMA) began to monitor a tropical depression over the South China Sea. The system generally moved northward slowly under a subtropical ridge, and then turned to northeast on the next day. Despite moving over warm waters, the depression remained poorly organized. It moved ashore near Hailing Island, Yangjiang, Guangdong Province at 10:35 a.m. CST on August 11 (02:35 UTC). The depression made an anti-clockwise loop inland and moved back to the sea later that day. The system moved slowly southeastward, because Yagi and Leepi in the northwestern Pacific prohibited the extension of the subtropical ridge, therefore the steering current remained weak for days in the South China Sea. After moving back to the sea, the depression gained some organization, and the Joint Typhoon Warning Center (JTWC) finally classified it as a tropical depression and gave the numerical designation 20W on August 12. After maintaining tropical depression status for more than 3 days, 20W finally intensified to a tropical storm and the JMA gave the international name Bebinca early on August 13. Throughout that day, Bebinca's low-level circulation center (LLCC) was exposed because of moderate to strong easterly wind shear. Despite this, the JTWC upgraded the system to a tropical storm later that day.
  Bebinca remained a sheared cyclone on August 14, while continued to slowly drifting to the east. After Leepi made landfall in Japan and dissipated, the subtropical ridge can finally extend and build over China, and Bebinca began to curve back to the west. Although wind shear remained strong on August 15, Bebinca still began to intensify as it was situated over very warm waters with 31 °C (88 °F), and the system was able to develop a central dense overcast. Bebinca made its second landfall in Leizhou, Guangdong at 9:40 p.m. CST (13:40 UTC), and emerged to the Gulf of Tonkin about four hours later. Once moving into the warm waters of the Gulf of Tonkin, Bebinca began another intensification trend. This prompted the JMA to upgrade Bebinca to a severe tropical storm, but it was revoked in the post-storm analysis. Bebinca weakened slightly before making its third and final landfall in Nam Định Province, Vietnam at 5:30 a.m. ICT on August 17 (22:30 UTC on August 16), with winds of 75 km/h (45 mph). Bebinca weakened quickly once moving inland, and the JTWC issued its final warning early on August 17. The JMA also downgraded Bebinca to a tropical depression, and Bebinca dissipated later that day, over Laos.
