The department attributed the weather conditions to the weakening of a high-pressure system over the North, the Northeast, and the South China Sea. The weak northeast monsoon prevails across the Gulf and the South. People should beware of the severe conditions that may cause flash flooding and water runoff.
The department cautioned drivers to be aware of poor visibility until October 23. From October 24 on, the South will experience heavy rain and all ships should proceed with caution and keep away from storms.
