After crossing Taiwan, Typhoon Megi made landfall in Hui'an County of Quanzhou City, in east China's Fujian Province, at 4:40 a.m. local time on Wednesday, September 28, bringing with it drenching rains that flooded roads and caused widespread disruption. At the time of landfall, China's National Meteorological Center recorded maximum sustained winds at 118 km/h. Megi has since been downgraded to a tropical storm, currently moving west-southwestward at 20 km/h into mainland China with a minimum central pressure of 996 mb and is expected to bring further rain before gradually dissipating later this week.

Meteorological Summary

Coastal areas of Fujian experienced between 200 and 300 mm of rain in just 24 hours—from Tuesday to Wednesday morning—with some areas receiving more than 300 mm, raising levels of local rivers above alert levels and elevating the risk of mudslides and flooding. At its largest, Typhoon Megi was 500 km in diameter. Megi is the 17th typhoon of the year, and the third storm to impact Taiwan in two weeks.

Reported Impacts

Fujian Province is experiencing widespread flooding caused by excessive rainfall. The provincial flood control office said the streets in the capital of Fuzhou are waterlogged. Winds have toppled trees, causing further disruption. Flight cancellations and school closures have been reported along the coast of Fujian. More than 120,000 fishermen were evacuated and 30,000 vessels were called into port in Fujian alone. Megi has also caused the collapse of several structures in Quanzhou, according to the Chinese News Service.

Exposure at Risk

Fujian is one of China’s more affluent provinces. Its capital, Fuzhou, is located on the coast and has a population of more than 7 million. Residents in urban areas typically live in mid- or high-rise apartment buildings, many of which have commercial establishments on the ground floor. Mid-rise buildings are often confined masonry, while high-rises tend to be reinforced concrete or steel. China’s commercial and industrial building stock is diverse, and generally more resistant to wind and water damage than residential structures.  Historically, dominant construction types in China are unreinforced masonry made from adobe or brick, or brick with a light wood frame. These are still prevalent in more rural areas and are unlikely to be insured.

Forecast Track

Continued weakening is expected as Megi moves farther into mainland China, bringing additional rain before gradually dissipating later this week.
