The remnants of Imelda dumped up to 43 inches of rain within three days in the areas between Winnie and Beaumont, east of Houston. Most of that rain fell in just 24 hours.
Some residents whose homes were flooded by Hurricane Harvey two years ago are now seeing rain seeping into their houses yet again.
"It was really just intense rainfall that wouldn't stop. It was very [Hurricane] Harvey-like," Harris County Sheriff Ed Gonzalez said.

A Harris County Sheriff's sergeant was heading to rescue a man stranded in floodwaters early Friday when the fast current trapped him, Sheriff Gonzalez said. The sergeant, who had lost all contact with the department, clung to a tree branch to avoid the quick current until both men could be rescued, Gonzalez said.
"We collectively just held our breath for a minute ... we're just all relieved," said the sheriff, who knows the sergeant personally.

Jayden Payne, a student at Aldine Senior High School in Houston, was in the car with his mom when he saw an SUV head into a ditch -- "and it was going down fast."
Payne said he ran over, dodging other cars, and dove into the water to help pull a mother and daughter to safety.
"I was frightened for the little girl because I could tell she was 4 years old. And I was like, 'She's too young for her life to get taken away right now,'" he told ABC News. "They were both too young."
