Hong Kong Observatory Issues Second Amber Rainstorm Warning Amid Heavy Rains

The Hong Kong Observatory issues second amber rainstorm warning this week, expecting heavy rain exceeding 30 millimetres per hour and potential flooding in low-lying areas. The warning was issued at 7:35 pm on April 20th, 2024, as thundery showers developed to the west of the Pearl River Estuary and began impacting Hong Kong.

Occasional showers and thunderstorms are forecast for the coming days as a trough of low pressure affects the coastal areas of Guangdong. The weather is expected to be predominantly cloudy, with showers and squally thunderstorms that could be heavy at times. Winds are anticipated to strengthen significantly on higher ground.

The trough of low pressure is likely to persist, affecting Guangdong's coastal areas and maintaining unsettled conditions in Hong Kong. By the middle of the week, the intensity of showers is expected to decrease as the trough begins to weaken, but thundery showers may return later in the week due to another trough of low pressure affecting southern China.

Why this matters: The heavy rains and potential flooding pose risks to public safety and could disrupt daily life in Hong Kong. The repeated amber rainstorm warnings this week highlight the need for residents to stay vigilant and prepared for rapidly changing weather conditions.

Temperatures are expected to range between 25 and 29 degrees Celsius. The Labour Department has reminded employers and contractors to ensure the safety of their employees, particularly those involved in electrical work. "Flash floods are possible," the Observatory warned, advising residents to take necessary precautions.

Strong winds reaching speeds of up to 105 kilometres per hour have been recorded, and a waterspout was spotted in Clear Water Bay. The Pearl River Estuary and surrounding areas are experiencing intense thundery showers due to the trough of low pressure. The forecast for the coming days includes cloudy skies, heavy showers, and severe squally thunderstorms, with occasional showers and thunderstorms expected throughout the week.
