Sawt Falasteen - Typhoon Saola weakens to a severe storm as it tracks along southern China

Tens of millions of people in the densely populated coastal areas of southern China had sheltered indoors on Friday ahead of the storm.

Saola had triggered Hong Kong's highest threat level on Friday evening -- issued only 16 times since World War II -- and registered winds of around 210 kilometres per hour at its peak.

It was downgraded before dawn on Saturday as the typhoon passed the city and tracked towards coastal areas of mainland China -- where it weakened into a severe tropical storm.

So far, Hong Kong has had no reported casualties and far less damage than that created by 2018's powerful Typhoon Mangkhut, but authorities warned people to stay away from the shoreline as Saola was still whipping up strong gales.

AFP journalists saw multiple fallen trees strewn across Hong Kong roads, broken windows, and crumpled scaffolding from under-construction buildings, while local media reported that solar panels had been ripped off rooftops.

"Yesterday was a bit scary," Angelie said as she ventured out to meet a friend under a blanket of constant rain.

"In our (residential) estate, there were a lot of trees fallen, and some windows were broken."

Saola left Thomas Wong, a shopkeeper in Causeway Bay, stranded overnight in his home goods store.

"I didn't leave my shop because the transportation was not running... I had no choice," Wong said, adding that he lived in the northern Hong Kong district of Tai Po.

A resident in Hong Kong's Heng Fa Chuen housing estate -- the site of devastation during the 2018 Typhoon Mangkhut -- said she felt "some swaying" in her building during the night

"But overall, we didn't feel unsafe," she told AFP, contrasting it to 2018's Mangkhut which had temporarily disrupted the supply of water and electricity in some housing blocks.

The last storm to earn the city's highest typhoon alert, Mangkhut shredded trees and unleashed floods across the city, leaving more than 300 people injured in its wake.

In mainland China, it killed six people and impacted the lives of more than three million others.

Hong Kong's Civil Aid Service said Saturday more than 500 people were deployed around the city to evaluate the damage, including volunteer workers who patrolled a low-lying fishing village in Lei Yue Mun district.

They removed twisted iron cladding to less wind-whipped areas and snapped photos of rising sea waters, as residents surveyed the pavement damage done to uprooted trees that pulled up concrete.

"I'm waiting to see if there is a storm surge and whether the waters will rise," one woman in Lei Yue Mun told a TV news station.

Hong Kong's airport gradually resumed flights, after mass cancellations and delays the day before, while neighbouring gambling hub Macau announced the reopening of casinos that had been closed for a day -- a rarity -- due to the severity of Saola.

- Frequent, unpredictable storms -

Saola made landfall in the Chinese coastal city of Zhuhai, where workers on Saturday moved metal railings from roads and cleared sand whipped from a nearby beach.

By afternoon, it had moved west to the tourist island of Hailing in Guangdong province, bringing sustained winds at a speed of 100 kilometres (62 miles) per hour.

China had initially warned that Saola "may become the strongest typhoon to make landfall" in the region since 1949, but by Saturday afternoon, Guangdong province downgraded its emergency response due to the weakened windspeed.

Across the South China Sea on Saturday, another typhoon, Haikui, tracked rapidly towards Taiwan, where authorities raised land and sea warnings, though the impact was expected to be mild.

Southern China is frequently hit in summer and autumn by typhoons that form in the warm oceans east of the Philippines and then travel west.

Climate change has made tropical storms more unpredictable while increasing their intensity, bringing more rain and stronger gusts that lead to flash floods and coastal damage, experts say.
