18th April 2024 – (Hong Kong) The Hong Kong Observatory has issued a warning at 8.45am today as a band of intense thundery showers, currently situated over western Guangdong, is shifting eastwards. It is anticipated that the showers will soon affect the vicinity of the Pearl River Estuary. Residents are advised to exercise caution and remain vigilant.

Thunderstorm Warning was issued at 7.26am and has been extended until 2pm today. Squally thunderstorms are expected to occur over Hong Kong. Meanwhile, intense gusts reaching 70 kilometres per hour or above may affect Hong Kong.

The coastal areas of Guangdong are presently under the influence of a trough of low pressure, resulting in the formation of the aforementioned band of intense thundery showers. This weather system is gradually making its way towards the Pearl River Estuary.

Today’s weather forecast for Hong Kong indicates mostly cloudy skies with a few showers and isolated thunderstorms. The daytime temperature is expected to reach a maximum of approximately 31 degrees Celsius. Additional showers are anticipated later in the day, accompanied by moderate south to southeasterly winds.

Looking ahead, Hong Kong can expect a continuation of scattered showers in the coming days, with hot daytime temperatures persisting. Sunday and early next week may bring an increase in showers, gradually intensifying into thunderstorms. A southerly airstream will influence the coastal areas of Guangdong, resulting in sporadic showers and daytime heat. Simultaneously, a trough of low pressure will introduce unsettled weather conditions to southern China. As the trough edges closer to the coast, heavy showers and squally thunderstorms are anticipated early next week. The influence of the trough is projected to persist throughout midweek.
