A week after Hurricane Harvey came ashore in Texas, rescuers kept up a marathon search for survivors on Friday as large pockets of land remained under water after one of the costliest natural disasters to hit the U.S.
The storm has displaced more than one million people with 44 feared dead from flooding that paralysed Houston, swelled river levels to record highs and knocked out the drinking water supply in Beaumont, Texas, a city of about 1,20,000 people.
With the presence of water-borne contaminants a growing concern, the National Weather Service issued flood watches from Arkansas into Ohio on Friday as the remnants of the storm made their way through the U.S. heartland.
Economic cost
The Neches River, which flows into Beaumont and nearby Port Arthur, was forecast for a record crest from Friday well above flood levels. The flooding and loss of drinking water forced the evacuation of a hospital on Thursday.
Moody’s Analytics estimated the economic cost from Harvey for southeastern Texas at $51 billion to $75 billion, ranking it among the costliest storms in U.S. history. Much of the damage has been to Houston, the U.S. energy hub. At least 44 people were dead or feared dead in six counties including and around Houston, officials said. Another 19 remained missing.
Some 7,79,000 Texans have been told to leave their homes and another 9,80,000 fled voluntarily amid dangers of new flooding from swollen rivers and reservoirs, according to federal estimates.
A new hurricane, Irma, had strengthened into a Category 3 storm, the midpoint of the five-step Saffir-Simpson scale, on Friday. It remained hundreds of miles from land but was forecast to possibly hit the U.S. territory of Puerto Rico, the Dominican Republic and neighbouring Haiti by the middle of next week.
Seventy percent of Harris County, which encompasses Houston and has a population of about 4.6 million people, was covered with 18 inches (45 cm) or more of water, county officials said.
As signs of normal life returned to Houston, there were concerns about health risks from bacteria and pollutants in flood water.
