'A new and different normal': Thousands driven from homes as Harvey hammers Houston

• At least 8people believed dead as a result of the storm.
• Another 51centimetres of rain still possible.
• More than 3,000 people rescued so far;30,000 expected to seek shelter.
• U.S. President Donald Trump to visit Texas on Tuesday.
• Flooding expected to peak Wednesday or Thursday in Houston.

Historic flooding from tropical storm Harvey is believed to have killed at least eightpeople in Texas and wasexpected to drive some 30,000 from their homes, as officials onMonday warned that floodwaters would likely rise in the comingdays as the storm hovers over the U.S. Gulf Coast.

National Guard troops, police officers, rescue workers andcivilians raced in helicopters, boats and special high-water
trucks to rescue the hundreds of people still stranded in andaround Houston, the nation's fourth-largest city.

Floodwaters reached the roof lines of single-storey homes Monday and The Associated Press reported people could be heard pleading for help from inside.

The storm was the most powerful hurricane to strike Texas inmore than 50 years when it came ashore on Friday near CorpusChristi, 354 kilometressouth of Houston.

The National Hurricane Center said Monday night that heavy rainfalls could bring 25 to 50 centimetres of rain overnight.

Death toll expected to rise

Local media put the death toll at eight so far. It is believed to have killed at least six people in HarrisCounty, where Houston is located, according to Tricia Bentley, aspokeswomanfor the county coroner's office, including a man whodied in a house fire and an elderly woman attempting to drivethrough flooded streets on the city's west side.

The number also includes a60-year-old woman who died in neighbouring Montgomery County when a tree fell on hertrailer home while she slept, according to the local medical examiner.

Police Chief Art Acevedo said he's "really worried about how many bodies we're going to find."

As stunned families surveyed the wreckage of destroyed homesand roads flooded or clogged with debris, Texas Gov.GregAbbott warned Houstonians to brace for a long recovery.

"We need to recognize this is going to be a new and different normal for this entire region," Abbott told reporters after touring Corpus Christi.

Unprecedented flooding

Harvey was expected to linger over Texas's Gulf Coast for thenext few days,with threats of flooding extending into Louisiana.

The storm was generating an amount of rain that would normally be seen only once in more than 1,000 years, said Edmond Russo, a deputy district engineer for the U.S. Army Corps of Engineers.

Harvey's centrewas 137 kilometressouth-southwest of Houston on Monday afternoon and forecast to arc slowly toward the city through Wednesday, with the worst floods expected later that day and on Thursday.

Virtually deserted

Schools and office buildings were closed throughout the metropolitan area, home to 6.8 million people, as chest-high water filled some neighbourhoods in the low-lying city.

Numerous refiners shut operations in the nation's refining and petrochemical hub.

The city's normally bustling business district was virtually deserted, with emergency vehicles making up most of the traffic. Most traffic signals were out and most businesses closed.

The U.S. Army Corps of Engineers said Monday that it was releasing water from the nearby Addicks and Barker reservoirs into Buffalo Bayou, the primary body of water running through Houston.

"The more they release it could go up and it could create even additional problems," Houston Mayor Sylvester Turner warned. But the release was said to be necessary to prevent an uncontrolled surge of water, which Turner said "would be exponentially worse."

Citizens to the rescue

Torrential rain also hit areas more than 240 kilometresaway, swelling rivers upstream and causing a surge that was heading toward the Houston area, where numerous rivers and streams already have been breached.

The high floodwaters made it hard for some residents who had fled their homes to find shelter. Christe Fletcher, 37, fled herhouse after it flooded to waist-deep, but was struggling to finda safe route to a nearby hotel.

Heather Hiscox spoke with Louise Walker, who is awaiting rescue at her neighbours' home because of flooding in Houston"It's kind of hard to get there because all of the roads areclosed," she said. "It's the worst experience you can gothrough."

Chris Thorn drove with a buddy from the Dallas area with their flat-bottom hunting boat to pull strangers out of the water.

"I couldn't sit at home and watch it on TV and do nothing since I have a boat and all the tools to help," he said.

'I don't even have flood insurance'

They got to Spring, Texas, where Cypress Creek had breached Interstate 45 and went to work, helping people out of a gated community near the creek.

"It's never flooded here," resident Lane Cross said from the front of Thorn's boat, holding his dog, Max. "I don't even have flood insurance."

By Monday night, 7,000 people had arrived at a shelter set up inside the George R. Brown Convention Center which originally had an estimated capacity of 5,000.

Red Cross spokesman Lloyd Ziel said that volunteers made more space inside the centre, which also was used to house Hurricane Katrina refugees from New Orleans in 2005, in part by pushing some cots closer together. A shortage of cots means some people will have to sleep on chairs or the floor

Many area residents were left in limbo, wondering whatremained of their flooded homes.

'I'm not complaining, we're alive'

Regina Costilla, 48, said she and her 16-year-old son hadbeen rescued from their home by a good Samaritan with a boat.She sat and worried until she was reunited with her husband andlarge dog, who had been left behind because they didn't fit intothe boat.

"I'm not complaining, we're alive," said Costilla. "When Isaw the forecast of the storm I said I'll be happy if we get out
with our lives."

Houston did not order an evacuation due to concerns about people being stranded on city highways now consumed by floods, Turner said.

FEMA's Long on Monday did not question the decision, saying the "evacuation of the city of Houston could take days, days, literally days."

Gov. Abbott, who had suggested on Friday that people leave thearea, declined to second-guess the mayor on Monday, tellingreporters, "Decisions about evacuations are something that arebehind us."

Trump to visit

U.S. President Donald Trump plans to go to Texas on Tuesday to survey the damage, a White House spokesperson said on Sunday. On Monday, he approved an emergency declaration for Louisiana.

Trump, facing the biggest U.S. natural disaster since he took office in January, signed a disaster proclamation for Texas on Friday, triggering federal relief efforts.

"We're dealing with Congress. As you know it's going to be a very expensive situation," Trump told reporters on Monday.

Trump's administration assured Congress that the $3 billion US balance in FEMA's disaster fund was enough to handle immediate needs, such as debris removal and temporary shelter for thousands of displaced residents. When lawmakers return next week, a multibillion-dollar aid package is likely to be added to their already packed agenda.
