25th April 2024 – (Hong Kong) Residents of Kwai Chung, Hong Kong, witnessed a striking phenomenon known as a ‘localised downpour’, where rain appeared to fall in a confined area, creating a column-like effect that captivated onlookers. Social media users quickly took to platforms to share images and express their amazement, with some humorously referring to the event as a “time tunnel” or even an “alien invasion”.

The spectacle occurred against a backdrop of unstable weather that has gripped the region in recent days. The Hong Kong Observatory has noted that this instability is likely to persist, with heavier rains expected tomorrow and intermittent showers and thunderstorms throughout the weekend. Residents planning to attend the forthcoming Labour Day fireworks display over Victoria Harbour on May 1st are advised to come prepared for potential rain and windy conditions.

Meteorologists attribute the peculiar ‘localized downpour’ to very fine-scale meteorological phenomena that can occur under certain atmospheric conditions. These conditions include the presence of a low-pressure trough, which has been affecting the Guangdong area and is expected to continue influencing the weather over the next few days with sudden heavy rains and strong thunderstorms.

Today, the Observatory issued a yellow rainstorm warning, indicating significant downpour risks. The weather has been predominantly cloudy with occasional heavy showers and thunderstorms, pushed along by moderate to fresh southerly to southeasterly winds. Temperatures in urban areas ranged from 24 to 27 degrees Celsius.

Looking ahead, the Observatory forecasts that the low-pressure trough will gradually move away early next week, leading to a decrease in rain intensity. However, the weather is expected to remain predominantly cloudy with scattered showers and thunderstorms over the weekend, with urban temperatures hovering between 24 and 28 degrees Celsius.
