The Hong Kong Observatory has issued a special weather advisory at 6:25 AM on May 7, 2025, warning residents of ongoing thunderstorms in the Pearl River Estuary. This weather event, influenced by a low-pressure trough, is expected to bring showers to various areas in Hong Kong throughout the morning.
According to the advisory, citizens are urged to stay alert to changing weather conditions, as the Observatory predicts that some regions will experience increased rainfall in the coming hours. The public is advised to carry umbrellas when going out and to be cautious of slippery roads. Additionally, outdoor workers are encouraged to take necessary safety measures, particularly avoiding areas that are prone to lightning strikes.
The situation follows a series of weather warnings issued the previous day. On May 6, 2025, at 4:45 PM, the Observatory had already alerted the public about heavy rain and thunderstorms affecting the Pearl River Estuary, particularly in the western and northern New Territories. This warning was prompted by a rainstorm area linked to the same low-pressure trough.
Later that evening, at around 8 PM, the Observatory extended its thunderstorm warning, anticipating severe thunderstorms in regions such as Tai Mo Shan and the western New Territories, effective until 10:30 PM. The forecast indicated that the lowest temperature for the night would hover around 27 degrees Celsius, with heavy rainfall and strong winds expected.
As the low-pressure trough affecting Guangdong gradually weakens, the weather in coastal areas is expected to stabilize over the next couple of days. The forecast for May 7 suggests that while the day will start with thunderstorms, there will be brief sunny intervals later on, with temperatures reaching a maximum of about 31 degrees Celsius in urban areas, and slightly higher in the New Territories.
However, the forecast remains cautious. The Observatory has indicated that another low-pressure trough is expected to approach the South China coast by the weekend, which could lead to further instability in weather conditions. This could affect the weather on Mother's Day, May 11, 2025, which is predicted to be cloudy with occasional showers and thunderstorms, with temperatures ranging from 23 to 27 degrees Celsius.
From May 8 to May 9, the weather is expected to be hot during the day, with temperatures potentially reaching up to 32 degrees Celsius on Friday, May 9. Overall, the next few days will see a mix of sunshine and showers, with the possibility of thunderstorms persisting intermittently.
As the Hong Kong Observatory continues to monitor the situation, updates will be provided to keep the public informed. Residents are encouraged to stay tuned for the latest weather forecasts and to take necessary precautions during this unpredictable weather period.
