10th August 2022 – (Hong Kong) Tropical Storm Mulan was around 500km away from Hong Kong and Strong Wind Signal, No. 3 was issued and maintained by Hong Kong Observatory until 6.20pm this evening.

The Hong Kong Observatory issued an analysis, saying that Mulan passed about 400 kilometres southwest of Hong Kong this morning. The satellite image shows that the circulation of Mulan was very broad. The rainbands brought squally heavy showers and thunderstorms to the coastal areas of Guangdong yesterday and today.

However, the Observatory explained that due to the relatively short duration of the gale which only affected a small part of Hong Kong, it did not reach the No 8 typhoon warning signal or No.8 storm signal standard. The Observatory said that at 2pm, Mulan gathered about 500 kilometres west-southwest of Hong Kong, and was expected to move west-northwestward at a speed of about 18 kilometres per hour, crossing the Leizhou Peninsula and the Beibu Gulf.

According to satellite cloud images, Mulan’s circulation is very broad, and its heavy rain belt is mainly concentrated in its periphery, with the characteristics of monsoon low pressure. The outer rainbands on the east side of Mulan brought squally heavy showers and thunderstorms to the coastal areas of Guangdong yesterday and today. During this period, more than 70 mm of rainfall was generally recorded in Hong Kong.
