Now Playing: The U.S. could end up with more flooding in the future as the Gulf of Mexico is expected to surge higher and higher in coming months, according to the U.N. Environment Program.

And that could mean more flooding on Texas highways and in the U-turns of Austin, Texas, which is one of the worst-hit cities.

A U.C. San Diego study found that the city is likely to see more than 50 inches of rain this year, more than double the normal amount of precipitation.

And the water levels are expected to rise as high as 20 inches, the study said.

“This is a very, very important city.

It is one that has been a very important part of Texas,” said Steve Riggs, a U.K.-based meteorologist with the University of Texas at Austin’s Climate Prediction Center.

“You’ve got to understand, there are a lot of people that have been very hard-hit, and a lot more are going to be affected by this than we thought.”

The flooding has already had a ripple effect on the city, as water levels have risen by up to 20 inches on some roads.

Some of those roads are not accessible to people, but the city of more than 5 million has already begun to reopen them to cars, trucks and even buses.

“People who have to walk the walk and not be able to go down the street because there is water on the road, people who can’t use the bus because there’s water on their way, people are having to walk or drive through floodwaters,” said Matt Hockley, director of the Texas Parks and Wildlife Department’s Division of Wildlife Services.

There are no signs that the flooding is getting worse.

A recent report by the National Weather Service found that Austin was expected to see 1,800 to 2,300 more inches of rainfall this month.

But even if rainfall continues at the same pace, Austin could experience at least another 1,000 to 1,400 more inches, according a report by The Weather Channel.
