Thundery showers to affect Hong Kong in next few hours, Amber Rainstorm Warning issued at 7.35pm (Update: 7.38pm)


20th April 2024 – (Hong Kong) In an announcement made at 6.45pm today, the Hong Kong Observatory issued a warning regarding the development of thundery showers to the west of the Pearl River Estuary, which may soon impact Hong Kong. Residents are advised to stay vigilant and be prepared for the imminent change in weather conditions. Currently, Guangdong is already experiencing showers and thunderstorms associated with a low-pressure trough.

The Hong Kong Observatory subsequently issued an Amber Rainstorm Warning Signal at 7.35pm. This indicates that heavy rain, exceeding 30 millimetres per hour, has already fallen or is expected to occur across Hong Kong. The rainfall is likely to persist, leading to potential flooding in low-lying and poorly drained areas.

To minimise the risks associated with heavy rain and flooding, individuals in vulnerable areas should take necessary precautions. Flash floods are a possibility, so it is important to avoid watercourses. Stay updated on traffic conditions and follow further announcements on the rainstorm by tuning in to radio broadcasts or watching television.

Following the issuance of a rainstorm warning by the Hong Kong Observatory, the Labour Department (LD) has issued a reminder to employers and contractors regarding the safety of their employees. The LD emphasizes the need for necessary work arrangements and appropriate safety measures, particularly for those involved in electrical work or handling electrical equipment.

The weather forecast for tonight and tomorrow predicts predominantly cloudy skies with intermittent showers and squally thunderstorms. The showers are expected to be particularly heavy initially. Temperatures will range between 25 and 29 degrees Celsius tomorrow, accompanied by moderate to fresh southerly winds.

Looking ahead, occasional showers and squally thunderstorms are anticipated over the next few days, with heavier showers occurring at times. However, midweek next week should witness a decrease in showers along the Guangdong coast as the trough of low pressure gradually weakens. Nevertheless, a subsequent trough of low pressure is expected to affect southern China in the latter part of next week, leading to thundery showers in the region.
