- The broad area of low pressure over the central and northern parts of the South China Sea is developing gradually, but its structure is still loose. If the broad area of low pressure further develops into a tropical cyclone this morning (28 August) and is located within 800 kilometres of Hong Kong, the Observatory will consider issuing the Standby Signal, No. 1 by then. The low pressure system is expected to move towards Hainan Island and the seas south of it. However, there are uncertainties in its intensity. Under the combined effect of the low pressure system and the ridge of high pressure over southeastern China, it will be windy with showers, thunderstorms and squalls over the northern part of the South China Sea and the coast of southern China today and tomorrow (28 and 29 August). There will be swells. Unless the low pressure system intensifies significantly, or adopts a track closer to the coast of Guangdong, the chance of persistent strong winds generally over the territory is expected to be relatively low. Members of the public should take note of the latest weather information from the Observatory, stay away from the shoreline and not to engage in water sports.
