HKO assesses need for Standby Signal No. 1 this evening to tmr morning

An area of low pressure within the broad trough of low pressure over the northern part of the South China Sea will develop gradually and edge closer to the coast of Guangdong. Since the convective clouds associated with it are mainly located at its southern side currently, it is expected to take some time to consolidate.

Whether it will develop into a tropical depression can only become more certain when it is relatively close to the coast of Guangdong. If the area of low pressure develops into a tropical depression, the Observatory will assess the need for issuing the Standby Signal, No. 1 this evening (13 July) to tomorrow morning (14 July).

According to the present forecast, the low pressure system will be closest to Hong Kong tomorrow morning, skirting within 100 kilometres of the territory.

Heavy showers, thunderstorms and squalls will affect Hong Kong tomorrow. There may be a need to issue rainstorm warning signals or Localised Heavy Rain Advisory.

Strong winds will prevail offshore. Flooding may occur in some low-lying areas. Showers will be heavy at times at first on Wednesday (15 July) and there will still be strong winds offshore.
