Taiwind Red Xia Residual Flow Brings Heavy Rainfall to Southern China

The Ministry of Water Resources has issued a warning about the continued impact of the residual circulation from Typhoon “Hongxia,” which has triggered heavy rainfall across multiple provinces in China, according to Xinhua News Agency. The agency’s analysis highlights that the storm’s remnants, though no longer classified as a typhoon, are maintaining significant meteorological activity, particularly in southern and central regions.

Heavy rainfall has been reported in Guangdong, Hubei, and Henan provinces, with the National Meteorological Center issuing flood warnings for these areas. The China News Service noted that the persistent moisture from the typhoon’s remnants is interacting with monsoonal systems, leading to prolonged and intense precipitation. In Guangdong, authorities have activated emergency response protocols, while Hubei’s flood control departments have reported rising river levels in several key locations.

Residual Effects and Regional Impacts

The residual effects of “Hongxia” are particularly evident in southern China, where the combination of the typhoon’s moisture and the summer monsoon has created a “southern sauna” phenomenon, according to the China Youth Daily. This term refers to the high humidity and temperatures that accompany the prolonged rainfall, exacerbating discomfort for residents. The article cited local meteorologists as stating that the humidity levels in Guangdong have reached high levels in some areas, with temperatures hovering around 32°C.

In central China, the impact is more focused on flooding risks. The People’s Daily reported that the Yangtze River basin, including Hubei and Hunan provinces, has seen increased water flow due to the heavy rains. The Hunan Provincial Flood Control and Drought Relief Headquarters has deployed personnel to monitor reservoir levels and assist in emergency response efforts. Meanwhile, Henan province has experienced localized flooding in rural areas, with the provincial government issuing advisories to avoid low-lying regions.

Further north, the impact of the typhoon’s residual circulation is less direct but still notable. The China News Service highlighted that the Beijing-Tianjin-Hebei region is preparing for a shift in weather patterns, with forecasts predicting a rise in temperatures and a decrease in precipitation by midweek. However, the National Meteorological Center warned that the interaction between the typhoon’s remnants and the northern jet stream could lead to unexpected weather fluctuations.

Meteorological Warnings and Public Response

The China Meteorological Administration has issued a yellow-level warning for heavy rainfall in Guangdong, Hubei, and Hunan, emphasizing the risk of flash floods and landslides. The agency’s latest report states that the region has received over 150mm of rainfall in the past 48 hours, with some areas exceeding 200mm. This has led to the closure of several highways and the suspension of train services in parts of Hubei and Henan.

Local governments have taken proactive measures to mitigate the impact. In Guangdong, the provincial flood control office has ordered the evacuation of residents from flood-prone zones, while Hubei’s authorities have activated emergency shelters in affected counties. The Hunan provincial government has also launched a public awareness campaign, urging citizens to avoid flooded roads and to stay informed through official channels.

The residual effects of “Hongxia” are not limited to China’s southern and central regions. The China News Service reported that the typhoon’s circulation has also contributed to heavy rainfall in Sichuan and Jilin provinces, where the National Meteorological Center has issued orange-level warnings for thunderstorms and heavy rain. In Sichuan, the Chengdu Meteorological Bureau noted that the region has experienced its wettest week of the year, with some areas recording over 300mm of rainfall since Monday.

As the typhoon’s remnants continue to influence weather patterns, meteorologists are monitoring the potential for further activity. The China Meteorological Administration stated that the system is expected to weaken by late week, but the lingering moisture could lead to isolated heavy rain events in southern China. The agency has urged residents to remain vigilant and to follow official guidance for safety.
