Dolly snarls toward Texas-Mexico line
Dolly was upgraded from a tropical storm Tuesday afternoon with sustained winds about 80 mph, and some strengthening of the Category 1 storm was forecast before landfall today.
A hurricane warning is in effect for the coast of Texas from Brownsville to Corpus Christi and in Mexico from Rio San Fernando northward.
In Mexico, Tamaulipas Gov. Eugenio Hernandez said officials planned to evacuate 23,000 people to government shelters in Matamoros, Soto La Marina and San Fernando.
Texas officials urged residents to move away from the Rio Grande levees because if Dolly continues to follow the same path as 1967's Hurricane Beulah, "the levees are not going to hold that much water," said Cameron County Emergency Management Coordinator Johnny Cavazos.
The first bands of rain began to pass over South Padre Island Tuesday afternoon and the surf continued to get rougher. Intermittent heavy downpours began moving through Brownsville by late afternoon. Forecasters predicted Dolly would dump 15 to 20 inches of rain and bring coastal storm surge flooding of 4 to 6 feet above normal high tide levels.
The storm, combined with levees that have deteriorated in the 41 years since Beulah swept up the Rio Grande, pose a major flooding threat to low-lying counties along the border. Beulah spawned more than 100 tornadoes across Texas and dumped 36 inches of rain in some parts of south Texas, killing 58 people and causing more than $1 billion in damage.
"We could have a triple-decker problem here," Cavazos told a meeting of more than 100 county and local officials Tuesday. "We believe that those (levees) will be breached if it continues on the same track. So please stay away from those levees."
Around Brownsville, levees protect the historical downtown as well as preserved buildings that were formerly part of Fort Brown on the University of Texas at Brownsville campus. Outside the city, agricultural land dominates the banks of the Rio Grande, but thousands of people live in low-lying colonias, often poor subdivisions built without water and sewer utilities.
The International Boundary and Water Commission, which operates a series of levees, dams and floodways in the lower Rio Grande Valley, put its personnel on standby alert. If needed, the IBWC will begin patrolling the levees around the clock looking for seepage and erosion, said spokeswoman Sally Spener.
