Observatory: Rain areas affect different regions at different times
As for Macau and Zhuhai, due to the forecast of rain, classes were suspended in advance.
Zheng explained that the time of the rainy area affecting different areas is different, because the rain this time moves from southwest to northeast, and Zhuhai and Macau are just west of the Pearl River Estuary, so it will be affected earlier, and it is expected that the rain will weaken early next week. Temperatures will also drop at the same time.
