“Further heavy rain could cause … serious road flooding and traffic congestion and could disrupt normal school hours,” the Hong Kong Observatory said. “Heavy rain will bring flash floods, and flooding is occurring or is expected to occur in watercourses.”
The forecaster issued an amber rainstorm warning at 9.45am, it was raised to red after an hour at 10.45am. Violent gusts of wind reaching 90 kilometres per hour or above may also affect the city, it added.
The forecaster said the coast of Guangdong was affected by a trough of low pressure, which would lead to heavy showers and squally thunderstorms in the region throughout the week.
Meanwhile, a waterspout, which are fast-rotating air columns above water that extend down from the base of clouds, was also spotted at Cheung Chau at about 10.30am.
“People should stay away from watercourses. Residents living in proximity to rivers should stay alert to weather and should consider evacuation if their homes may become flooded,” the forecaster said.
