Look: Floods fill tunnels leading to Detroit airport, people rescued from cars in Ohio

Heavy rains across parts of the United States flooded an Ohio highway where people were rescued from their cars, covered the Las Vegas Strip with water and temporarily closed a busy airport terminal outside Detroit.

Parts of the western United States have been deluged in recent weeks with rain from Tropical Storm Hilary, and much of the central US was beaten down by deadly sweltering heat. In Hawaii and Washington, emergency crews battled catastrophic wildfires.

Areas in southeast Michigan got over 12.7 centimetres of rain by Thursday morning, resulting in street flooding in the Detroit area, including tunnels leading to Detroit Metropolitan Airport in the suburb of Romulus, officials said. Officials reopened the airport's McNamara Terminal on Thursday afternoon.

Michigan Gov. Gretchen Whitmer activated the State Emergency Operations Centre on Thursday evening to provide support to affected communities “as they respond to the impacts of flooding".

A few hours earlier Thursday, Mitzi Hale and her three sons ate some snacks out of a vending machine as they awaited word on the status of the terminal.

The 42-year-old and her sons — 10, 13 and 20 — were to board a mid-morning flight to Florida. They were scheduled to visit Walt Disney World’s Magic Kingdom theme park on Friday before embarking on a Disney cruise through the Caribbean, beginning on Saturday.

Making matters worse: The quartet had the same vacation booked for last November, but missed out due to a tropical storm that struck the region.

“We’re just having flashbacks,” said Hale, who lives in Brighton, Michigan.

Scientists say that without extensive study they cannot directly link a single weather event to climate change, but that climate change is responsible for more intense and more frequent extreme events such as storms, droughts, floods and wildfires. Climate change is largely caused by human activities that emit carbon dioxide, methane and other greenhouse gases into the atmosphere, according to the vast majority of peer-reviewed studies, science organizations and climate scientists.

The overnight storms caused power outages across Michigan, concentrated in the Detroit area. Later in the day, after severe storms in the western part of the state, more than 100,000 homes and businesses were in the dark across Michigan, according to poweroutage.us.

“We were getting rainfall rates above an inch an hour, which is pretty significant,” said Brian Cromwell, a meteorologist with the National Weather Service in Detroit.

Cromwell added that more severe thunderstorms with torrential rains were possible over the region on Thursday evening.

Up to 20 centimetres of rain also hit some areas of north-central Ohio, according to Brian Mitchell with the National Weather Service in Cleveland.

In Lakewood, Ohio, 10 people were rescued from seven cars on a section of Interstate 90 on Wednesday night after their vehicles got stuck in the water that reached to the windows, Capt. Gary Stone said. The highway was shut down in both directions at one point. No one was hurt.

“It was a bad mess down there,” Stone said, noting that while Lakewood is often hit by bad storms coming off of Lake Erie, this kind of flooding was unheard of.
