Floodwaters rise in Houston Thirteen people were confirmed dead

Floodwaters kept rising Tuesday across much of Texas as storms dumped almost another foot of rain on the Houston area, stranding hundreds of motorists and inundating the famously congested highways that serve the nation's fourth-largest city.Meanwhile, the search went on for at least 13 people who were still missing, including a group that disappeared after a vacation home was swept down the river and slammed into a bridge.
Several more fatalities were reported — three in Houston and one more in Central Texas. That brought to 14 the number of people killed by the holiday weekend storms in Texas and Oklahoma.
The water continued rising overnight as about 11 more inches of rain fell, much of it in a six-hour period.
The floodwaters affected virtually every part of the city and paralyzed some areas. Firefighters carried out more than 500 water rescues, most involving stranded motorists. At least 2,500 vehicles were abandoned by drivers seeking higher ground, officials said.
"Given the magnitude and how quickly it happened, in such a short period of time, I 've never seen this before," said Rick Flanagan, Houston's emergency management coordinator.

Officials in Hays County, about 35 miles southwest of Austin, said 30 people who had been reported as missing were accounted for by mid-afternoon Tuesday.
Crews were also searching for victims and assessing damage just across the Texas-Mexico border in Ciudad Acuna, where a tornado killed 13 people Monday.
Some of the worst flooding in Texas was in Wimberley, a popular tourist town along the Blanco in the corridor between Austin and San Antonio. That's where the vacation home was swept away.
The "search component" of the mission ended Monday night, meaning no more survivors were expected to be found, said Trey Hatt, a spokesman for the Hays County Emergency Operations Center.
Eight of those missing from the destroyed house were friends and family who had gathered for the holiday, said Kristi Wyatt, a spokeswoman for the City of San Marcos. She said three more were members of another family in a separate situation. An unrelated person was also missing, Wyatt said.
Young children were believed to among the missing.
The Blanco crested above 40 feet — more than triple its flood stage of 13 feet. The river swamped Interstate 35 and closed parts of the busy north-south highway. Rescuers used pontoon boats and a helicopter to pull people out.
Hundreds of trees along the Blanco were uprooted or snapped, and they collected in piles of debris up to 20 feet high.
The deaths in Texas included a man whose body was pulled from the Blanco; a 14-year-old who was found with his dog in a storm drain; a high school senior who died Saturday after her car was caught in high water; and a man whose mobile home was destroyed by a reported tornado.
The Oklahoma Department of Emergency Management also reported four fatalities between Saturday and Monday after severe flooding and reports of tornadoes.
In Ciudad Acuna, Mayor Evaristo Perez Rivera said 300 people were treated at local hospitals after the twister, and up to 200 homes had been completely destroyed in the city of 125,000 across from Del Rio, Texas.
Thirteen people were confirmed dead — 10 adults and three infants, including one that was ripped from its mother's arms by the storm.
