By evening, the storm had entered the South China Sea and continued on its westward track at about 20 kilometers per hour. In Thailand, the system will intensify the monsoon trough over the North and Upper Northeast, as well as the southwest monsoon over the Andaman Sea and Gulf of Thailand from September 23 to 26. This will bring widespread rain, with heavy to very heavy downpours in the North, Northeast, Central, and Eastern regions, including Bangkok and surrounding provinces. Marine conditions are also expected to worsen, with waves of 2 to 3 meters in the Andaman Sea and upper Gulf of Thailand, rising above 3 meters during thunderstorms. Mariners are urged to take caution, and small boats in the upper Andaman Sea should remain ashore between September 24 and 26.
