Story highlights Many residents trapped in their homes are facing hours without being rescued

Woman: "You see police ... and everything coming by on boats, but they're rescuing the emergency cases first"

(CNN) Rising floodwaters have filled much of the first floor of the Houston home where 11 members of Leidys Shull's family are taking refuge.

Worried about four children under the age of six, Shull called 911 Sunday and talked to the fire department. They put her on a waiting list for being rescued, she said. Then they told her they'd come at 3 in the morning, she said, but nobody showed up.
