After a period of multiple tropical cyclones swirling simultaneously, the western North Pacific has recently turned calm, yet potential atmospheric changes are quietly brewing. The Hong Kong Observatory (HKO) issued a "Weather Word" commentary yesterday (Aug 14), noting that a broad trough of low pressure will gradually approach the Guangdong coast in the mid-to-late part of next week, and an area of low pressure may form.
The Observatory analysed that sea surface temperatures over the northern South China Sea will be relatively high at that time. If coupled with weak vertical wind shear and upper-level divergence, the low-pressure area may have a chance to intensify further into a tropical depression or a tropical cyclone of a higher intensity.
The broad trough of low pressure is expected to start affecting Hong Kong from next Wednesday (Aug 19), bringing unsettled weather.
The Observatory forecasts:
19 (Wed) to 23 (Sun): Five consecutive days of mainly cloudy weather with occasional showers and thunderstorms. Easterly winds of Force 4 to 5, later shifting to east to southeasterly winds of Force 4 to 5.
21 (Fri) to 22 (Sat): The worst conditions, with occasional showers and squally thunderstorms expected; rain will be more frequent in some areas.
The Observatory stated that it will continue to closely monitor the development of potential tropical cyclones over the western North Pacific and the South China Sea, and members of the public should stay tuned to the latest weather forecasts.
