Hong Kong Flood Threat to Close out Week

A soaking end to the week is shaping up for southeastern China, including Hong Kong, significantly heightening concerns for flash flooding.

While the week started on a relatively dry note, southeastern China will soon become a pathway for rounds of rain and thunderstorms as a front stalls overhead.

The front will first bring generally spotty showers and thunderstorms to Hong Kong Thursday afternoon through Friday morning (local time) before more numerous thunderstorms and steadier rain follow from later Friday through the weekend.

Rainfall totals will average 50 to 100 mm (2 to 4 inches) in Hong Kong and across southeastern China, but locally greater totals are possible in the higher terrain and from the heaviest downpours.

That amount of rain threatens to cause flash flooding, especially in low-lying and poor drainage areas, and landslides along the slopes of the higher terrain.

The impending flood danger is not confined to southeastern China but extends eastward to Taiwan, according to Meteorologist Eric Wanenchak.

Wanenchak also pointed out that Hong Kong is in the midst of abnormally wet stretch of weather ahead of its rainy season.

"[Hong Kong] was really dry to start the year, but the rain has been way above normal since mid-March," Wanenchak stated.

Rainfall from Jan. 1 to March 15 was held to under 6 mm (0.24 of an inch), but totaled 325.6 mm (12.82 inches) from March 15 to April 23.

The rainfall through this weekend will only add to that latter total with potentially more showers and thunderstorms to close out April next week.
