It is the flood Vietnam's Ho Chi Minh City has learned to expect.

Forecasters warned on Sept. 27 that high tides could combine with heavy rain to increase the risk of flooding in Ho Chi Minh City, one of the world's most climate-vulnerable cities. As heavy rain combined with the tide on the evening of Sept. 30, the Saigon river and smaller waterways spilled onto the roads of Vietnam's commercial capital.

Tropical weather that surged onshore from the Pacific soaked more of the U.S. on Wednesday while forecasters announced yet another hurricane off the coast of Mexico.

The new hurricane, Rachel, is expected to develop rapidly and could become a major one with sustained winds topping 111 mph (178 kph). The storm was far offshore, however, and posed no threat to land.

Glaciers in Switzerland – the home to the most in the Alps – lost 5.5% of their ice volume this year, the second-biggest percentage drop on record due to heat waves and low winter snowfall, experts report.

"Alpine glaciers have no chance of surviving in the long term under such conditions," the GLAMOS Swiss glacier monitoring service and Swiss Academy of Sciences said in a statement released Thursday.

As former Hurricane Polo weakened over northwestern Mexico on Tuesday evening, the storm's remnants battered the U.S. Southwest, flooding roadways and forcing residents in small New Mexico towns to evacuate over concerns about a dam failing.

Polo had struck the Mexican state of Baja California Sur in the morning with maximum sustained winds of 110 mph (177 kph). It crossed the Gulf of California and weakened to become a tropical storm as it moved inland to the northeast.

Wind whipped Mexico's northern Pacific coast and water began to flood some streets Monday as Hurricane Polo bore down on Baja California Sur, threatening flash floods and mudslides. Meanwhile, Hurricane Nolo could still bring torrential rain to parts of Hawaii even as the storm edges away from the state.

In Puerto San Carlos, a fishing town of about 5,700 people, high tides and pounding waves from Polo were breaching sea barriers as residents worried for their homes in the mostly empty town. Hundreds of people in the region evacuated, hunkering down in nearby shelters in schools and other facilities.

The Trump administration released new fuel economy standards Monday that relax regulatory requirements for automakers to control pollution from gasoline-powered cars and light trucks.

Fuel economy requirements set out how far new vehicles need to travel on a gallon of gasoline. The change furthers President Donald Trump's promise to revoke policies that encouraged or created incentives for the production of electric vehicles.

Rain eases in Bangkok but persistent flooding forces thousands to leave home

Rain eased in Thailand 's capital on Sunday, but flooding persisted in several low-lying areas, with thousands forced to move into temporary shelters. At least eight people were reported killed in the past 10 days nationwide.

A United Nations report released Thursday shows that there is still a multibillion dollar funding gap for preserving tropical forests, which are key to fighting climate change.

A new fund that aims to raise $100 million for firefighting in South America, home to the Amazon rainforest, was announced this week at New York Climate Week and the U.N. General Assembly. But the funding excludes vast swathes of forests in Africa and Southeast Asia.

Five cheetah cubs had to survive a weather scare and the illness of their mother after their birth at the Prague Zoo. But they are doing well now, the zoo said on Friday.

The zoo said the quintuplets — four males and one female — that were born on June 18 had faced a tough time from the start.

Nepal's prime minister scolded fellow world leaders Thursday, saying the nation's recent deadly flood reminds a warming world that climate change keeps hurting people who didn't cause the crisis but now need help.

The August disaster "was not just a local tragedy. It was a warning to the world. And I ask you today: Have you really heard that warning?" Nepali Prime Minister Balendra Shah said at the U.N. General Assembly on Thursday night. "Nearly three years ago, standing in the shadow of our Mount Everest, the secretary-general of the United Nations warned about humanity about the madness and impending climate disaster."
