Just in on CNN, the Astrodome is full up and is turning buses away. Buses are being told, and I quote, "find another city". In the background behind the reporter, three buses were pulling off out of the parking lot.
Aaron Brown noted that whatever the population of the Astrodome, it's far below the previous estimated capacity of 25k.
Video of the interior of the Astrodome showed that, sure enough, the field was basically filled with (occupied) cots.
