Wildfires have been wreaking havoc in the southern regions of China, particularly affecting the Sichuan and Yunnan Provinces, since March 15. These fires have caused environmental destruction, human casualties, and widespread displacement of communities.

The impact of the wildfires has prompted significant emergency responses, including the evacuation of approximately 4 900 people from Yajiang County in Sichuan Province.

JMA Himawari-9 satellite image below shows pyrocumulonimbus (pyroCb) clouds mixed with smoke spawned by a wildfire in Sichuan on March 16. The cloud formed at around 06:20 UTC and by 09:40 UTC it extended over 650 km (404 miles) to the NNE.

Forecasters, utilizing data from the JRC GWIS, have predicted the fire danger levels for the upcoming 24 hours, indicating a range from high to very extreme over Yunnan Province.
The conditions in Sichuan Province are expected to improve, offering hope that the firefighting efforts there might soon lead to a containment of the wildfires.
