The death toll from Typhoon Rai has risen to 24, while about five million people are without electricity. Twelve of the victims, including a South Korean national, were from the central province of Cebu, police and local officials said. The other fatalities were from the nearby province of Negros Occidental, the central city of Iloilo, Siargao Island and three provinces in the southern region of Mindanao. Electricity was cut off in 13 central and southern provinces, affecting about five million people, according to the Philippine Rural Electric Cooperatives Association. The strongest typhoon to hit the Philippines this year uprooted trees, toppled power lines and flooded villages as it barrelled across the archipelago on Friday, leaving at least 24 people dead. More than five million people fled their homes and beachfront resorts as Typhoon Rai pummelled the southern and central regions of the country, knocking out communications in some areas and tearing roofs off buildings. Philippine Airlines, Cebu Air and other carriers cancelled more than 200 flights. An IT Park in Cebu City was destroyed due to strong winds, according to a post on Twitter. Rai was a super typhoon when it slammed into Siargao Island on Thursday, packing maximum sustained winds of 195 kilometres an hour (120 miles). By Friday, wind speeds had eased to 155kmh, the state weather forecaster said. “We are seeing people walking in the streets, many of them shell-shocked,” ABS-CBN correspondent Dennis Datu reported from the hard-hit city of Surigao on the southern island of Mindanao. “All buildings sustained heavy damage, including the provincial disaster office. It looks like it’s been hit by a bomb.” Datu said the main roads leading into the coastal city had been cut off by landslides, fallen trees and toppled power poles. More than five million people had sought emergency shelter as the typhoon charged across the Pacific Ocean and smashed into the country. Surigao City Mayor Ernesto Matugas told ABS-CBN that Rai ravaged the city of for several hours, causing “severe” damage. “The wind was very strong,” Matugas said. “Everything sustained damage – roofs blown off, access roads blocked by landslides.” Scores of flights were cancelled across the country and dozens of ports temporarily closed as the weather bureau warned several-metre-high storm surges could cause “life-threatening flooding” in low-lying coastal areas. “The devastation is hard to explain,” said Joel Darunday, 37, a tour operator in the central island province of Bohol, who was hunkered down at home with his family when the storm ripped off the roof. “It was very strong. The last time I experienced something like this was back in the 1980s.” People in the central city of Cebu cleared fallen trees, branches and debris from roads as clean-up efforts got under way. Verified photos taken in nearby Lapu-Lapu city showed roadside buildings flattened by the storm, while sheets of corrugated iron roofing and branches littered streets. A building and gym belonging to the Philippine Red Cross in the central province of Southern Leyte were badly damaged, with part of the roof torn off, photos posted by the organisation on Twitter showed. Rai, locally named Odette, is hitting the Philippines late in the typhoon season, with most cyclones developing between July and October. Scientists have long warned that typhoons are becoming more powerful, and strengthening more rapidly, as the world becomes warmer because of human-driven climate change . A super typhoon is the equivalent of a category five hurricane in the United States. The Earth tends to experience around five storms of that power a year. Rai was moving across the Visayas region towards Palawan on Friday and was expected to emerge Saturday over the South China Sea, heading towards Vietnam. Philippines – ranked as one of the world’s most vulnerable countries to the impacts of climate change – is hit by an average of 20 storms and typhoons every year, which typically wipe out harvests, homes and infrastructure in already impoverished areas. The deadliest cyclone on record in the Philippines was Super Typhoon Haiyan, which left more than 7,300 people dead or missing in 2013.
