HOUSTON (AP) - The director of the National Weather Service is warning that the catastrophic flooding that's overwhelming Houston and other parts of Texas will worsen in the coming days and then be slow to recede once Harvey finally moves on.
Director Louis Uccellini said during a news conference Monday that up to 20 inches of rain could fall in the coming days, on top of the more than 30 inches some places have already seen.
He says some of the heaviest rainfall Monday, at a pace of 6 inches an hour, will fall east of Houston in places such as Beaumont and Lake Charles, Louisiana.
The Federal Emergency Management Agency is asking for volunteers to help Texas recover from Harvey.
William "Brock" Long, FEMA administrator, told a news conference in Washington Monday that "we need citizens to be involved," because the storm and resulting flooding is greater than the government can handle.
Long urges individuals and organizations to check the website or call 1-800-621-FEMA to find out how to help. He's asking for financial donations and for people "to figure out how to get involved as we help Texas find a new normal."
