Tropical Storm Harvey has made landfall again in the US state of Louisiana after hovering in the Gulf of Mexico. Low-lying New Orleans, devastated by 2005's Hurricane Katrina, is bracing to receive up to 25cms of rain in 36 hours, with flash floods a major risk. <br/><br/>The storm, which earlier achieved hurricane status, has dumped record rainfall in the region. Large parts of the Texas city of Houston are underwater and more than 20 people are reported dead. Thousands of people there have fled their homes in search of emergency shelter amid severe flooding. <br/><br/>Houston, America's fourth most populous city, has implemented a night-time curfew to prevent looting from abandoned homes as authorities and volunteers battle to rescue stranded people and provide shelter for those made homeless by the rising waters.<br/><br/>President Donald Trump visited Texas yesterday to survey the damage brought by Harvey. He arrived in Corpus Christi, where Hurricane Harvey first made landfall on Friday, with First Lady Melania Trump. <br/><br/>He will not be visiting Houston. The White House said he did not want his visit to disrupt the emergency response. Mr Trump has declared a federal state of emergency in both Texas and Louisiana. The move releases emergency government funding and other assistance. Harvey was the most powerful hurricane to hit Texas in more than 50 years when it made landfall at Corpus Christi, south-west of Houston. <br/><br/>In a heartwarming gesture, many Indian-Americans living in safer Texas neighbourhoods are helping many Houstonians still stuck by Hurricane Harvey by opening their homes and distributing fresh food, medical and essential needs. Many Indian business organisations and places of worship have also opened their doors to shelter those who have been displaced. <br/><br/>Meanwhile, an Indian student has died after he nearly drowned in a swollen lake in the US State of Texas where Hurricane Harvey has wreaked havoc. Nikhil Bhatia, a student at the Texas A&M University was rescued from the Lake Bryan where he along with another Indian girl Shalini Sikngh had gone for swimming. <br/><br/>According to the consulate officials, Bhatia succumbed to his injuries today while Shalini continues to be in a critical condition. <br/><br/>UN Chief Antonio Guterres has expressed concern over the flooding and extensive damage caused by Hurricane Harvey. The UN Secretary General's spokesperson said, Mr. Guterres is following the developments in Texas with great concern.
