low-pressure trough

Hong Kong is expected to experience heavy showers and squally thunderstorms over the next few days due to a low-pressure trough and active southerly airstream. Authorities reported six landslide incidents and damage to a retaining wall between Friday and Saturday.

Hong Kong issued a red rainstorm warning as heavy thundery showers are expected from Friday to Monday. The warning was escalated due to 50mm of rain falling in an hour or likely to fall across the city.

Hong Kong’s observatory has warned of heavy rain and squally thunderstorms in the coming week, driven by a low-pressure trough. It remains uncertain whether the trough will develop into a tropical cyclone, with convective clouds affecting the central South China Sea expected to bring severe weather to the city.

The Hong Kong Observatory issued an amber rainstorm warning, advising residents to prepare for heavy rain caused by a low-pressure trough along the southern Chinese coast. The warning was activated at 11:10am on Sunday, indicating widespread heavy rain is imminent.

Severe weather warnings have been issued for Queensland, New South Wales, and Tasmania as heavy rains and flash flooding threaten multiple regions. A low-pressure trough drawing tropical moisture is driving the wet weather, according to meteorologist Ilana Cherny of the Bureau of Meteorology.
