The Hong Kong Observatory issued three rainstorm warnings within a 90-minute period on Saturday as severe weather affected the region, prompting disruptions to school schedules and leading to a lightning strike injury on Lantau Island.

The first alert, an amber rainstorm warning—the lowest level in the Observatory's three-tier system—was issued at 11:50 a.m. The warning was then quickly upgraded to red at 12:15 p.m., triggering the suspension of afternoon classes across local schools. The red warning was subsequently downgraded back to amber at 1:20 p.m., before all warnings were canceled 50 minutes later. These rapid changes elicited frustration from some parents and students, with social media posts expressing concerns over the cancellation and delays of secondary school graduation ceremonies and the disruption to kindergarten classes.

During the unsettled weather, police reported receiving a call around noon regarding a group of hikers on Ngong Ping Road, including one woman and five men. One of the men was struck by lightning and suffered a leg injury. Authorities did not immediately confirm whether the injured individual was transported to a medical facility.

Rainfall was particularly heavy in the New Territories, with Tai Po and Sai Kung experiencing intense showers. The Observatory noted that the unsettled weather is expected to continue into the coming week due to a trough of low pressure remaining over southern China and the northern South China Sea. Forecasters warned of ongoing showers and squally thunderstorms throughout the region.

The nine-day forecast indicates that cloud cover will persist over the weekend, accompanied by periods of heavy rain and occasional thunderstorms. As the low-pressure system gradually moves away from the Guangdong coast, a subtropical ridge will build over southern mainland China, bringing a reduction in rainfall and rising temperatures. By midweek, daytime highs are expected to reach up to 33 degrees Celsius.

Despite the temporary easing of conditions, a new broad trough of low pressure is forecast to move into the central and northern South China Sea later next week, potentially bringing further unsettled weather to the area.
