3-day Weather Forecast Data as of 04:50 HKT 09/Jul/2025

General Situation: Under the influence of a southwesterly airstream, the weather will remain very hot with showers over the coast of Guangdong today. Tropical Cyclone Danas will move across the vicinity of Fujian today. It will then edge closer to Guangdong and weaken gradually. The trough of low pressure associated with the remnant of Danas is expected to bring heavy showers and squally thunderstorms to Guangdong and the northern part of the South China Sea in the middle and latter parts of this week. With the weakening of the trough of low pressure, showers will ease off gradually and it will be brighter early next week.
