Residents of some rural southeast Texas counties braced for more flooding on Monday along a river that is expected to crest at a record level just two years after it had run dry in places because of drought. National Weather Service meteorologists predicted that the Brazos river would crest at 53.5 feet by midday Tuesday in Fort Bend County, three feet above the previous record and topping a 1994 flood that caused extensive damage. During four days of torrential rain, six people have died in floods along the Brazos, which runs from New Mexico to the Gulf of Mexico.
