Heavy rain in Hong Kong on Thursday has prompted officials to issue warnings of potential flash flooding as the remnants of Typhoon Danas sweep through southern China and the territory. The typhoon originally made landfall on Taiwan's west coast earlier in the week, leading to casualties and widespread power outages.

After causing destruction in Taiwan, where two individuals reportedly perished, the typhoon moved across the Taiwan Strait and hit mainland China, where it was downgraded to a tropical depression by Wednesday morning. As it traveled inland across southeast China, rainfall reached alarming levels, with certain areas recording up to 17.2 inches.

Meteorologists predict that even as Typhoon Danas weakens, it could still produce up to three inches of rainfall per hour until Friday. The storm’s trajectory is expected to affect Guangdong province, which is home to approximately 127 million residents, thereby raising concerns over flash flooding, landslides, and other weather-related hazards.

In Hong Kong, the combination of remnant winds from the typhoon and ongoing monsoonal rains has resulted in heavy rainfall and severe thunderstorms. As a precaution, local authorities suspended classes for Friday and issued a red rain warning, considered to be the second highest level of alert, indicating that more than 1.9 inches of rain might fall within an hour.

Winds gusting up to 73 miles per hour have also been reported, leading to advisories for residents to remain indoors. A notable reading of gusts reaching 43 miles per hour was taken on Sha Chau Island, which is situated near the city’s airport.

As the storm continues to progress through the region, residents are encouraged to prepare for possible extreme weather conditions and to stay informed through local advisories.
