Turner later announced via Twitter that he was pushing back the start time to midnight, ” … to allow volunteers and others to do their great work.”

As of late Tuesday night, the death toll stood at 18, officials said. federal and local agencies said they’d rescued more than 13,000 people from the flood waters and more shelters would open.

The NRG Center will become the next major shelter and was expected to open by 10 p.m. Houston time, the Houston Chronicle and ABC13 reported. The center will hold up to 10,000 evacuees, according to KHOU.
