Police said the toddlers were in their father's car, which was swept away just after midnight Friday after it stalled on a bridge in Corsicana. The children's father was trying to pull them from the vehicle when it was carried away, police said.
The body of a man whose vehicle was swept against a guard rail by rising waters also was found Saturday. The vehicle's passenger got out safely, police said.
In Fort Worth, a woman and her 2 1/2-year-old son died Friday night after she tried to drive across a flooded road, said fire department spokesman Lt. Kent Worley.
The woman's 1 1/2-year-old son, who was presumed dead, had not been found by Saturday afternoon.
Worley said the woman apparently had stopped at the crossing but decided to drive across after a van passed her and made it safely through already deep water. Her car was swept down a drainage ditch that empties into a creek, and was caught in trees about 75 to 100 yards downstream.
Johnny Campbell, 22, wrapped a tow chain around his waist and had three people hold it as he waded through waist-deep water toward the car.
``I saw her banging on the window and screaming for someone to help her,'' Campbell told the Fort Worth Star-Telegram. ``When I got to the car, I touched her hand, but water swept the car away, down into the creek.''
Storms pushed into the Houston area Saturday morning, bringing hail and at least one tornado.
