FEMA adminstrator, Brock Long on KHOU live news broadcast at 6:30 a.m. (CDT) said people were told to shelter in place in Houston and no evacuation order given because the weather forecast didn’t indicate where, over a large area, the water was going to flow. “Pinpointing what watershed that rain is going to go into is dang near impossible . . . “, he said. They didn’t know until it was actually happening. He said to evacuate a city of over 2 million would take days.
