Floodwaters deepened across much of Texas as storms dumped almost another foot of rain on the Houston area, stranding hundreds of motorists in the nation's fourth-largest city. Meanwhile, the search went on for at least 13 missing people, including a group that disappeared after a vacation home was swept away. Several more fatalities were reported—four in Houston and one more in Central Texas. That brought to 14 the number of people killed by the holiday weekend storms in Texas and Oklahoma. By this evening, most rivers had receded back within their banks. Forecasts called for a 20% to 40% chance of thunderstorms through the rest of the week in Houston. (More Texas stories.)
