A storm forecast to be the strongest to hit Myanmar in more than a decade made landfall near the Bangladesh border on Sunday, raising fears of a humanitarian catastrophe.
The storm moved ashore on Sunday afternoon in the coastal area around Cox’s Bazar, according to Bangladesh’s meteorological department. The Bangladeshi city is home to the world’s largest refugee encampment.
By Sunday morning, maximum sustained winds had reached 160 miles per hour, with gusts surpassing 180 miles per hour, according to the Joint Typhoon Warning Center, making it a Category 5 storm. That is the highest rating on the Saffir-Simpson Scale and indicates potential for catastrophic damage.
There were reports from Myanmar of damaged homes and boats, and one social media user posted a clip that appeared to show the moment when a communications tower toppled in strong wind. Video from a witness in Sittwe, on Myanmar’s coast, showed strong winds, flooded streets and buildings with roofs partly torn off.
Even before the cyclone moved ashore, U Hla Moe, a representative from a rescue team in the city of Tachileik, in the east of the country, said that a landslide caused by heavy rain had killed two people in the early hours of Sunday when it buried them in their house while they were sleeping. The local news media reported that at least four more people had died in the west and center of the country.
Ko Win Maung, a rescue worker in Sittwe, said that the water level was now about five feet and that his team was leaving to rescue an older couple stuck on their roof.
“Their house is now under water,” he said.
Abdusattor Esoev, the chief of mission in Bangladesh for the United Nations Migrations agency, wrote on Twitter that the cyclone was damaging facilities in the Rohingya refugee camp.
Officials and storm watchers expressed cautious hope that the region could be spared the storm’s worst possible damage as it weakened over land.
The program has prepared enough food to help more than 400,000 people in the Rakhine State in Myanmar and neighboring areas for one month. Food is also ready to be dispatched in and around the Rohingya refugee camps.
Mostofa Kamal, a weather and climate researcher at the University of Saskatchewan, wrote on social media that as the center of the storm began passing between Saint Martin Island and Maungdaw District in Myanmar, the tide was going out. This mitigates the effect of storm surge.
“So far, the cyclone is passing through the north coastal area of Cox’s Bazar, and no reports of damage have been received as of yet,” said Muhammad Shaheen Imran, the district administrator.
The Bangladesh Meteorological Center said on Sunday that the center of the cyclone had crossed Cox’s Bazar at 3 p.m., and that it would finish crossing the coast by Sunday evening and weaken gradually.
The storm, Cyclone Mocha, formed over the southern Bay of Bengal on Thursday and drenched western Myanmar as it churned northeast, with heavy rain, strong winds and storm surges, according to the Global Disaster Alert and Coordination System.
Days before the storm hit, Myanmar and Bangladesh began deploying thousands of volunteers and ordering evacuations from low-lying areas, in a region that is home to some of the world’s poorest people, who are especially vulnerable to increasingly severe weather events.
“Cyclone Mocha serves as a stark reminder to us of the devastating effects of climate change,” the United Nations Development Program in Bangladesh said on Twitter.
In Myanmar, the risk of devastation is compounded by a civil war that has displaced about 1.8 million people across the country, with the region south of the Bangladesh border being an active fighting zone and home to several large refugee camps.
In Cox’s Bazar, more than 200,000 people had been sent to 1,600 shelters. There is capacity to accommodate about 500,000 people, according to district officials. More than a million Rohingya people live in the sprawling camps.
With a storm of this intensity, storm surge — the bulge of water that is pushed with the winds as a storm nears the coast — has been a major concern near the cyclone’s landfall and to the south of it. Storm surge is often the greatest threat to life and property, according to the Hurricane Center.
Mocha looks likely to be the strongest storm to make landfall in Myanmar since Cyclone Giri, which in 2010 packed winds of 143 miles per hour, according to the National Oceanic and Atmospheric Administration’s historical cyclone tracks. That storm killed at least 45 people in Myanmar.
The term “cyclone” refers to a type of tropical cyclone — the umbrella term for all such storms, like hurricanes and typhoons — that forms in the Bay of Bengal or the Arabian Sea, both in the northern Indian Ocean. Scientists say that climate change has helped intensify storms, because the unusually warm ocean temperatures provide more energy to fuel them.
Cyclone Mocha comes as a deadly heat wave has been searing Southeast Asia for weeks. In April, Dhaka, the capital of Bangladesh, hit 105.1 degrees Fahrenheit, its highest temperature in six decades.
The Bay of Bengal, in the northeastern part of the Indian Ocean, has had a long history of major storms. In 2008, Cyclone Nargis became the second-deadliest tropical cyclone on record and the deadliest in Myanmar, killing more than 135,000 people. In 2007, Cyclone Sidr struck Bangladesh, killing more than 3,000 people.
