The slow-churning remnants of Tropical Storm Imelda that flooded parts of Texas left at least two people dead and rescue crews with boats scrambling to reach stranded drivers and families trapped in their homes during a relentless downpour that drew comparisons to Hurricane Harvey two years ago.By Thursday night, floodwaters had started receding in most of the Houston area, said the city's mayor, Sylvester Turner. Law enforcement officers planned to work well into the night to clear freeways of vehicles stalled and abandoned because of flooding, Houston Police Chief Art Acevedo said.Officials in Harris County, which includes Houston, said there had been a combination of at least 1,700 high-water rescues and evacuations to get people to shelter as the longevity and intensity of the rain quickly came to surprise even those who had been bracing for floods. The storm also flooded parts of southwestern Louisiana.More than 900 flights were canceled or delayed in Houston. Further along the Texas Gulf Coast, authorities at one point warned that a levee could break near Beaumont in Jefferson County. During Harvey, Beaumont's only pump station was swamped by floodwaters, leaving residents without water service for more than a week.Imelda's remnants Thursday led to the deaths of two men. A 19-year-old man drowned and was electrocuted while trying to move his horse to safety, according to a message from his family shared by the Jefferson County Sheriff's Office. Crystal Holmes, a spokeswoman for the department, said the death occurred during a lightning storm.A man in his 40s or 50s drowned when he tried to drive a van through 8-foot-deep floodwaters near Bush Intercontinental Airport in Houston during the Thursday afternoon rush hour, Harris County Sheriff Ed Gonzalez said. 1805

The pictures are horrific, and the stories behind the devastating crashes are heartbreaking.In one accident, 17-year-old Annaleah and 13-year-old Mary died in the backseat of their car, after a truck hit them and pushed the car underneath a tractor-trailer. Their mother, Marianne Karth, is haunted by it. “It's a very devastating crash. It's like the most devasting you can have,” Karth says. Lois Durso also lost her 26-old-daughter, Roya, in one of these same types of crashes.“Her hair was on the tires of the trailer, so we know it crushed her,” Durso recalls. Eric Hein experienced a similar tragedy. His 16-year-old son, Riley, died on his way to marching band practice after getting trapped underneath a tractor-trailer truck.“He went underneath the trailer,” Hein recalls. “His car got dragged for half a mile until it was engulfed in flames, and the fire killed him.” Tragedy brought all three parents together. Now, perseverance pushes them forward as they take steps to prevent these types of crashes. Karth and Durso organized a crash test in Washington, D.C. just weeks after members of Congress reintroduced the Stop Underrides Act, which would update and strengthen safety laws, including requiring tractor trailers to have guards on the sides to help prevent cars from ending up underneath them.“Seeing is believing, and for them to witness with their own eyes and own ears and to have it be something they see,” Karth says of their crash test. “Crash into the side of the trailer with a side guard and without to see the life and death difference.” Past legislation has stalled, but the parents hope this dramatic demonstration will be enough to get Congress to take action. Tests have shown when installed properly, guards can make a difference and keep cars from sliding underneath trailers. “It's not the crash that kills, it's the underride,” explains Durso. “If you can prevent the underride, there's a chance the vehicle occupants will survive.” Groups representing the trucking industry have concerns about the cost and say the guards add extra weight and can impact how tractor trailers can maneuver. However, parents say those concerns will not slow down their effort and they remain driven to save lives. “I lost my son. I don't want somebody else to go through this tragedy. These are preventable deaths,” says Hein. 2357

TripAdvisor has defended itself against accusations of misleading travelers by failing to stop some of its highest ranked hotels winning their status with fake reviews.UK consumer group Which? Travel analyzed a total of almost 250,000 reviews for the 10 top-ranked hotels in 10 global tourist destinations, from Las Vegas to Cape Town. It found that one in seven of the hotels had "blatant hallmarks" of fake reviews, with others raising "serious concerns."But TripAdvisor called the analysis "flawed" and said its more sophisticated detection tools were able to weed out fraudulent feedback.Which? Travel said that when it reported 15 of the worst cases to TripAdvisor, the reviews giant -- now one of the world's biggest travel websites -- admitted that all but one of the hotels in question had been caught using fake reviews in the past year.Six had previously been penalized, and two had received a "red badge warning" -- where TripAdvisor warns users that the hotel is suspected of using fake reviews, and has "repeatedly failed to remedy its behavior and refuses to cooperate with TripAdvisor's investigators."Yet, Which? Travel said it found that the review patterns had continued unabated despite the measures, and the red badges had been removed.The group has accused TripAdvisor of a "lack of serious ongoing action to address repeated abuse of the system."It says that five-star reviews left by new users who have written no other reviews should be a red flag. Its analysis compared the proportion of first-time five-star reviews with that of first-time three-star reviews, which are less likely to be faked.In total, it studied 247,277 reviews."TripAdvisor's failure to stop fake reviews and take strong action against hotels that abuse the system risks misleading millions of travelers and potentially ruining their holidays," said Which? Travel's Naomi Leach.TripAdvisor has removed hundreds of reviews in light of the investigation, Which? Travel claimed."Striking" evidence of fake reviewsHotels in the Middle East had "striking" amounts of fake positive reviews, according to the research. TripAdvisor docked 730 five-star reviews of the "best" hotel in Jordan following the analysis -- but the hotel has not been given a red badge. It remains in the top 10 in the country.At the top-ranking hotel in Cairo, 79% of five-star reviews came from one-time contributors. Just 14% of three-star reviews came from similar accounts.The hotel has lost its status as a result of the reviews' deletion.Las Vegas was another hotspot for fake reviews. At two of the top-rated hotels, almost half the five-star reviews came from one-time contributors. For a competitor which did not arouse suspicion, the figure was just 3%.Some of the top-ranked hotels in London, Paris, Barcelona and Cape Town "gave reason for suspicion," the research showed, but failed to demonstrate the same patterns across the board.Repeat offendersTripAdvisor called the analysis "based on a flawed understanding of fake review patterns," adding that "it is simply far too simplistic to assume all first-time reviewers are suspicious."It said that Which? Travel did not have access to IP [internet protocol] information or location data, both of which TripAdvisor uses to detect fake reviews."We analyze hundreds of data points about each review -- most of which only we have access to -- and we combine that data with a wealth of knowledge and understanding of review patterns that our team of experts has gained from tracking hundreds of millions of reviews over a near 20-year period," said the company."This includes an ability to track and analyze first-time reviews in far more detail and with far more rigor than Which's team was able to do."Online reviews influence an annual estimated ￡23 billion ( billion) of booking transactions in the UK alone, according to the UK government."Sites like TripAdvisor must do more to ensure the information on their platforms is reliable," said Naomi Leach."If they continue to fall short, they should be compelled to make changes so holidaymakers are no longer at risk of being duped by a flood of fake reviews." 4152
