From April 7 to the 9, the weather will be cloudy to overcast with occasional showers. Thunderstorms are expected from April 10 to 11. Starting from April 12, thunderstorms will become more pronounced, accompanied by short-duration heavy rainfall, short-term strong winds, and lightning. Given the unpredictable weather, it is advisable to dress appropriately and carry an umbrella when going out.
The flood season in Guangdong usually begins from late March to early April and lasts until October, during which severe convective weather is frequent. The "Dragon Boat Water" period, around the Dragon Boat Festival, is characterized by concentrated heavy rainfall. It often brings continuous days of heavy, torrential rains, and even extremely torrential rain.
According to related departments, the flood season in Guangdong this year will start slightly earlier than the historical average. The "Dragon Boat Water" period from May 21 to June 20 will be the concentrated rainfall period in the province.
6-day weather forecast for Guangzhou
Risks during the concentrated rainfall period
Flood Risks
The Xijiang River may experience floods with a recurrence interval of about five years, and the Beijiang River may face floods with a recurrence interval of about ten years. Some small and medium-sized rivers may even encounter floods with a recurrence interval of twenty years or more.
It is necessary to be vigilant against sudden heavy rainfall-induced small and medium-sized river floods, flash floods, and geological disasters. Close attention should be paid to the hidden dangers of collapses, landslides, and mudslides in the low-mountain and hilly areas of northern, northwestern, western, and eastern Guangdong, as well as in the residual hill distribution areas of the Pearl River Delta.
Transportation Risks
During holidays like May Day and the Dragon Boat Festival, when passenger flow surges, the risks of road traffic accidents and water-borne vessel incidents increase. Attention should be paid to preventing safety risks associated with tourist charter buses and vehicles transporting hazardous goods.
Construction Risks
In the construction field, attention should be paid to potential damage to temporary prefabricated houses, construction scaffolds, tower cranes, and other lifting machinery, as well as the falling of glass curtain wall components.
High-Temperature Risks
High-temperature weather will exacerbate safety risks in production and daily life. Outdoor workers should be aware of the occupational health risks of heatstroke and dehydration. Enterprises should pay attention to the risks of hazardous chemical storage tanks, static electricity accumulation, and equipment failures. Safety in the use of old power distribution facilities and new - energy vehicle charging piles should also be monitored.
Fire Risks
It is predicted that in the early part of the second quarter, most areas of Guangdong will have a relatively high forest fire danger level. In particular, some periods in northern, eastern, western, and northern Pearl River Delta regions will have a high or extremely high forest fire danger level.
In conclusion, with the upcoming changes in the weather and the associated risks, it is crucial for individuals, enterprises, and relevant departments in Guangdong to take appropriate preventive measures to ensure safety during this period.
