What is the location of the flooding?
As of July 7, 2026, persistent heavy rainfall from Typhoon Maysak has triggered widespread flooding and dam breaches across southern China, particularly in the Guangxi region (1).
Overflowing rivers, saturated ground, and repeated downpours have damaged infrastructure and inundated urban and rural communities.
Additionally, Super Typhoon Bavi is advancing across the Pacific toward Taiwan and eastern China, forecast to bring extremely heavy rain from Thursday onward (2).
Which cities or areas are affected by the flooding?
Typhoon Maysak and severe weather impacts have affected multiple cities and provinces across southern and central China, including:
- Guangxi (Binyang, Fangchenggang, Guigang, Hengzhou, Nanning—most severely affected)
- Guizhou
- Hubei (Ezhou, Huanggang, Huangshi, Xianning)
- Hunan
- Jiangsu
- Shandong
What is the current containment status of the flooding?
Containment remains challenging as flooding continues across Guangxi. Rescue and relief operations are ongoing following breaches at the Liulan and Yunbiao reservoirs in Hengzhou.
Water levels at 70 monitoring stations on 55 rivers remain above warning levels, while additional heavy rainfall is forecast, increasing the risk of further flooding (3).
Are there any evacuation orders or alerts in place?
China has issued red-level flood warnings across Guangxi and activated the highest emergency response in affected areas. Approximately 48,000 residents have been evacuated from Nanning and surrounding communities.
Authorities continue urging residents to avoid flood-prone areas and follow emergency advisories as heavy rainfall, flash floods, and landslide risks persist (4).
How can I protect myself from mold after flooding?
It’s important to take steps to prevent mold after a flood.
- Before entering a flooded area, make sure it is safe and free from electrical hazards or structural damage.
- Use protective gear: wear gloves, goggles, and a KN95/FFP2 mask to minimize exposure to mold spores.
- If there is still standing water, remove it as quickly as possible. Use pumps, wet-dry vacuums, or buckets to extract the water.
- Open windows and doors to facilitate air circulation and use fans, dehumidifiers, and HVAC systems to help dry the space. This step is crucial within the first 24-48 hours after flooding to prevent mold growth.
- Remove and discard any items that have been severely damaged by floodwater and cannot be thoroughly cleaned and dried. This includes carpets, upholstered furniture, mattresses, and any other porous materials.
- Thoroughly clean all hard surfaces with a detergent or cleaner suitable for mold remediation. Use a solution of 1.5 cups of bleach mixed with one gallon of water to disinfect nonporous surfaces. Never mix bleach with ammonia or other cleaning products, as the fumes are toxic.
- Maintain an indoor relative humidity (RH) of 35-50%. High humidity promotes mold growth, so consider using dehumidifiers in damp areas.
- Run a high-performance air purifier for mold, both during and after the mold removal work.
- If the flooding and mold damage are extensive, consider contacting professionals specializing in mold remediation to ensure proper cleanup and restoration.
Remember, mold can pose health risks, so it's important to take these steps promptly and thoroughly. If you experience persistent mold-related health issues or have concerns about extensive mold growth, consult with a medical professional or a mold remediation specialist.
