flooding

About 2% of U.S. homes are at risk of being flooded by the end of the century, thanks to rising sea levels. And the reason for rising sea levels, according to the National Oceanic and Atmospheric Administration, is climate change. But flood risk is not translating into lower property values in some areas along the coast.

A broad analysis of federal records finds that homeowners hoping to relocate out of flood zones in the U.S. don't have equal access to the main source of federal funding meant to help them.

Flood waters are slowly beginning to recede, but large areas of southeast Texas remain flooded Friday. Emergency crews continue to perform rescues from water-soaked neighborhoods. And officials work to get a broader sense of the damage left by Tropical Depression Imelda, a catastrophic weather event that swamped hundreds of cars and homes, and has claimed the lives of at least four people.

If you’re looking to buy a house in Texas, the homeowner is now required to tell you if it has ever flooded. Likewise, if you own a home that’s flooded, be prepared to disclose that under expanded state regulations that took effect this month.

Two Texas floodgates have collapsed in the last two years, and the Guadalupe-Blanco River Authority warns four more lakes are in danger of the same fate.

Tropical Storm Barry is beginning to take a toll on the central Gulf Coast, bringing high winds and heavy rains to parts of southeastern Louisiana, where residents have been preparing to cope with flooding and power outages.

As Barry slowly approached land, an oil rig southwest of the mouth of the Mississippi River reported "sustained winds of 76 mph and a wind gust of 87 mph," the National Hurricane Center said Friday.

In New Orleans, officials told residents to get off the streets and shelter in place.

Tropical Storm Barry formed in the Gulf of Mexico on Thursday, and it could become a hurricane by late Friday, the National Hurricane Center says. Forecasters say the storm could bring a storm surge and heavy rains to Louisiana.

Barry is now predicted to become a Category 1 hurricane shortly before making landfall Saturday morning. Its maximum winds are expected to reach only around 75 mph — but officials are warning of perilous flash floods and other hazards.

Gov. Greg Abbott on Wednesday urged city leaders and residents to prepare for potential severe weather this weekend.

In Texas, the city of Austin's water utility has issued a citywide boil water notice as it struggles with the impact of debris from flooding on its water treatment capabilities.

"The high level of debris, silt and mud requires extended filtration that slows the process of getting treated water into the system," Austin Water said in a press release. "To provide necessary water pressure for fire protection, plants must distribute water at treatment levels not typical of the utility's high standards for consumption."

As floodwaters from former-Hurricane Florence's massive rains continue to flow through the Carolinas, the end of the storm's damage is nowhere in sight.

Some of the worst flooding during this past weekend's East Coast storm happened during high tides.

Shoreline tides are getting progressively higher. A soon-to-be-published report obtained by NPR predicts a future where flooding will be a weekly event in some coastal parts of the country.

Hurricane Harvey brought more rain than any other hurricane in recorded U.S. history, the National Hurricane Center says.

The center released its final report on the record-breaking storm this morning, putting the death toll at at least 68, all in Texas, with 36 of those in the Houston and Harris County area. Harvey is second only to Hurricane Katrina in terms of storm damage, as well, the center found, with an estimated cost of $125 billion in damages, compared to Katrina’s $160 billion.

After Hurricane Harvey, some Texas residents, politicians and scientists are wondering whether the whole U.S. system for predicting floods is any good.

The storm's deluge flooded parts of southeast Texas that had rarely, or never, been underwater before. Some areas got more than 50 inches of rain in a few days. "When the numbers started coming in it was a little scary," says Matt Zeve, the director of operations for the Harris County Flood Control District, which includes Houston.

The floodwaters from Hurricane Harvey had to go somewhere.

In late August, Hurricane Harvey brought record rainfall to Houston. In mid-October, the city's two large federal reservoirs have finally been emptied of the massive amount of water that had filled each of them to the brim.

From Texas Standard:

Up to 500,000 cars took on water during Hurricane Harvey. Not having a vehicle in car-dependent Texas could be a significant hardship. And those looking for a used car to replace a flooded one should be wary of buying storm-damaged rides.

On Saturday in Denham Springs, Louisiana, about 15 miles east of Baton Rouge, the parking lot of a Sam’s Club was turned into a one-stop shop for flood victims.

Just days earlier the entire area was under water, but now this is where people can grab a shopping cart, get free cleaning supplies, cases of water, and ice.

Louisiana is entering recovery mode after devastating flooding killed 13 people and damaged at least 60,000 homes across 20 parishes.

But as Louisiana Gov. John Bel Edwards told CNN, that process is "going to take many months." He added that even though this flooding was "unprecedented and historic," many are "just now realizing how significant it was."
