Days of flooding in southeastern Texas have reportedly killed at least six people, and more rain is in the forecast.

The Brazos River, which runs 840 miles across much of the state, has already risen to record levels, submerging neighborhoods west of Houston and forcing hundreds of people to evacuate, according to The Associated Press.

The National Weather Service predicts that 4 to 5 more inches of rain are expected around Houston through the weekend.

In already waterlogged areas, just 1 inch would be enough to cause more flooding, the service warned.

Just two years ago, the Brazos River had run dry in some places due to drought, the AP says. The river appears to have crested at 54.23 feet, an NWS meteorologist tells the news service, but may remain in "major flood stage" for days longer.

The historic water levels have damaged hundreds of homes, Al Ortiz of Houston Public Media reports on Morning Edition.

Felix Lozano, who lives in Richmond, Texas — about 30 miles southwest of Houston — told Ortiz that his house was filled with 6 inches of water. A neighbor's house had a foot, he says.

Here's more from Ortiz's report:

"Lozano climbs into a little kayak and using a broom as an improvised oar, paddles around the neighborhood, mostly of mobile homes, checking out the damage. ..."Lozano's son, Oscar, says it may be time to find a new home." 'With the way that it's been going last year, the year before, just a month ago, I think we are gonna have to think about moving, at least to higher ground, further away from the Brazos River.'" 'I've never experienced what we have experienced this past year, year and a half, with the rains and the flooding,' another Richmond resident said."

Last year, around Memorial Day, floods devastated the Houston area. This April, more than a thousand people were evacuated from Northern Houston during another so-called historic flood event.

NPR's John Burnett, reporting from Austin over the weekend, said more than 2,000 inmates were evacuated from prisons in low-lying regions and that multiple cars had been washed off flooded roads.

"Some students had to sleep in their elementary school when high water prevented buses from taking them home," John said.
