Catastrophic flooding overwhelming Houston and other parts of Texas will worsen in the coming days and then be slow to recede once Hurricane Harvey finally moves on, the director of the National Weather Service has warned.
Louis Uccellini said up to 20 inches (51cms) of rain could fall in the coming days, on top of the more than 30ins (76cms) some places have already seen.
He told a news conference that some of the heaviest rainfall on Monday, at a pace of six inches (15cms) an hour, will fall east of Houston in places such as Beaumont and Lake Charles, Louisiana.
