On October 23, in response to the impact of a cold front moving south and Typhoon “Tammy,” which is shifting westward, the waters of the Pearl River Estuary in Guangdong experienced significant wind and waves, causing multiple shipping routes to shut down. As of 5:05 PM, typhoon warning signals had been activated in several areas including Shantou, Chenghai, Chao’nan, and Nan’ao.
The Guangdong Provincial Office of Flood Control, Drought Relief, and Typhoon Defense (referred to as the “Three Defense Office”) issued an urgent notice on the same day, urging relevant regions and departments to enhance their maritime wind prevention measures. They mandated that by 8 PM, all fishing vessels operating east of the Pearl River Estuary, including those in Shenzhen, must return to port for safety.
Meteorological authorities in Guangdong reported that at 11 AM on the same day, the center of Typhoon “Tammy,” categorized as a tropical storm, was approximately 380 kilometers northeast of Manila, with maximum winds near the center reaching 23 meters per second (about 9 on the Beaufort scale) and a minimum central pressure of 990 hPa.
Experts anticipate that “Tammy” will continue to move westward at a speed of 15 to 20 kilometers per hour, gradually intensifying. It is expected to enter the eastern waters of the central and northern South China Sea between the evening and night of October 24, and then head towards the southeastern waters of Hainan from October 25 to 27.
Due to the combined effects of the cold air and “Tammy,” winds over Guangdong’s sea have been increasing and are expected to remain strong. Between October 23 and 24, wind speeds in the eastern Guangdong sea will range from 6 to 9 on the Beaufort scale, with gusts reaching force 10. From October 25 to 26, the wind will moderate slightly, ranging from 6 to 8, with gusts reaching force 9.
The Three Defense Office has also issued a directive that mandates all fishing vessels operating east of the Pearl River Estuary must return to port by 8 PM on October 23. Personnel involved in aquaculture, marine ranching, and offshore wind energy construction must all evacuate to shore, and activities such as fishing, boating, and yachting are prohibited until further notice.
