DALLAS—Another round of heavy rains drenched parts of East Texas on Friday morning, flooding numerous roads and stranding at least one driver on top of his pickup truck, authorities said.

A man was rescued by the New Summerfield Fire Department in Cherokee County after his truck got stuck on a flooded road in Cherokee County, a dispatcher said.

The overnight deluge also forced roads to be closed in Rusk, Smith, Leon, Panola and Van Zandt counties, officials said Friday morning. In Anderson County, flooding washed out a county road bridge, a dispatcher said.

With Texas rivers and lakes filled already filled to the brim, emergency officials braced for forecasts of more rain and flooding.  Storms pounding Texas since May 23 have damaged or destroyed 1,000 homes, killed 13 people and left four missing.

The National Weather Service said 1 to 3 inches of rain could fall Friday with heavier amounts in some areas.

“Mostly this time of year we’re fighting wild fires ... The problem with this is, the water won’t go away,” Jack Colley, chief of the state’s Division of Emergency Management, said Thursday.

All of the state’s major river basins are at flood stage, the first time that has happened since 1957. Major flooding was forecast on the Guadalupe River in Victoria and Calhoun counties where the river was expected to crest near Bloomington at just over 27 feet early Saturday. Flood stage is 20 feet.

Areas of concern also include the Brazos, Sabine and Trinity rivers and Nueces River near Corpus Christi, Colley said.

Concerns eased Thursday that a full Lake Texoma along the Oklahoma-Texas line would send floodwaters into the Red River.

Ross Adkins, a spokesman for the U.S. Army Corps of Engineers in Tulsa, Okla., said about 6 inches of water was expected to go over the spillway next to Denison Dam in the next couple of days, which will keep the river full but was not expected to cause any flooding. The last major flood was nearly 5 feet over the spillway in 1990.

Michael Gittinger, meteorologist with the National Weather Service, said a series of low pressure systems that have hovered over Texas for three weeks combined with moist bands of air from the Gulf of Mexico have fueled the near-record rainfall.

Forecast models predict fast-moving energy from the jet stream will push the low pressure system north through Arkansas and toward the East Coast. Rain chances for North Texas drop to 10 percent this Saturday for the first time in weeks and will stay there through early next week, he said.

Colley said the cost of property damage has not yet been assessed. He said the state has already mobilized its largest ever flood response efforts of search and rescue teams and aid for flood damaged areas.

Assistance has come from government agencies helping in search and rescue and cleanup operations, as well as private charities such as the American Red Cross and Salvation Army operating shelters and feeding centers.

The impacted area covers 49 counties and 48,000 square miles from North Texas to the Rio Grande Valley, a section roughly the size of the state of Mississippi.

Joel Veeneman, a meteorologist with the National Weather Service, said the Frio, Guadalupe and Nueces rivers had passed flood stage and could stay there for the next two to three days.

Most areas in South Texas have seen more than a foot of rain since Monday, he said.

The latest death from the storms in Texas occurred early Thursday morning near Clifton in Bosque County. Leslie Featherston, 37, of Whitney, died when the car she was driving hydroplaned, collided with a curb and plunged into a creek, said Kathy Smith, spokeswoman for the Texas Department of Public Safety.

Four people have been reported missing, including two Leander men whose sport utility vehicle was found submerged in a creek near Smithwick on June 28 and a 6-year-old boy swept into the Gulf of Mexico on Tuesday as strong currents ripped him from his father’s arms at the mouth of the Brazos River in Freeport. A Cameron man was reported missing over the weekend in Milam County, and authorities were searching near Little River.

Gov. Rick Perry has activated more than 250 Texas National Guard soldiers to help response efforts. President Bush has already declared Cooke, Coryell, Denton, Grayson, Lampasas and Tarrant counties as federal disaster areas.

Perry also requested federal disaster declarations for Burnet, Eastland, Parker, Starr, Webb and Wichita counties. Since mid-June, Perry has issue state disaster declarations for 44 counties.
