Rainfall and flooding, which left five people dead and displaced thousands over the weekend, have continued in the Philippines following Typhoon Wipha, which is now barrelling towards the coast of northern Vietnam as a severe tropical storm.

As of 6am local time in Vietnam on Tuesday (23:00 GMT), Wipha was situated 60km (37 miles) off the coast of Haiphong City, with wind speeds of up to 102 kph (63 mph), and was moving southwest at a speed of 15 kph (9.3 mph), according to Vietnam’s national weather forecast agency.

No casualties or damage have been reported so far, while an estimated 350,000 Vietnamese soldiers are on standby as the country’s weather agency expects up to 500mm (20 inches) of rainfall, which could cause dangerous flooding and landslides.

Expected to make landfall in Hung Yen and Ninh Binh provinces, located south of the capital, Hanoi, Wipha is forecast to weaken to a low-pressure event on Tuesday night, the agency said.

Floodwaters driven by torrential rains in the aftermath of Typhoon Wipha brought much of life in the Philippine capital, Manila, to a halt on Tuesday, with tens of thousands evacuated from their homes and at least two people believed missing.

Schools and government offices remained closed in Manila and surrounding provinces after a night of rain that saw the region’s Marikina River burst its banks.

More than 23,000 people living along the river were evacuated and took shelter in schools, village halls and covered courtyards. Another 25,000 more were evacuated in the metropolitan area’s Quezon and Caloocan cities.

An elderly woman and her driver were swept down a swollen stream as they attempted to cross a bridge in Caloocan, John Paul Nietes, an emergency operations centre assistant supervisor, told the AFP news agency.

“Their car was recovered last night. The rescue operation is continuing, but as of today, they haven’t found either of them,” he said.

According to the National Disaster Risk Reduction and Management Council in the Philippines, five people have been reported killed as of Monday, and at least another five were reported injured following Typhoon Wipha, local news outlet Enquirer.net reported. Seven people are also missing, according to the council.

At least 20 storms or typhoons strike or come near the Philippines each year, with the country’s poorest regions typically the hardest hit. Their impact has become more deadly and destructive as storms grow more powerful due to climate change.

Earlier this year, Super Typhoon Yagi hit Vietnam, killing about 300 people and causing some $3.3bn in damage.
