Across the border in Texas, the town of Deweyville remained cut off by record rainfall that swelled the Sabine River to historic levels. TxDOT says both the westbound and eastbound lanes of I-10 at the Texas-Louisiana border are now closed.
State officials of Texas and Louisiana were considering closure of highway Interstate 10 near the state line on Tuesday morning. The emergency management office in Orange County, Texas, told CNN: "We are presently diverting traffic off Interstate 10 to prepare for the eventual and likely shutdown of the interstate".
Water from the overflowing Sabine River is up near the roadway. He said flooding has become a yearly issue but that the weekend's floods were the worst he's seen in nine terms as mayor.
The Sabine's flood stage is 4 feet, and the National Weather Service said it was cresting Wednesday at 7.5 feet. Parts of the region may not see flood waters begin to recede for days, he said after the tour that included flying over flooded areas by helicopter.
The hardest-hit parts of Texas have been in the southeastern part of the state, where "dozens if not hundreds" of high water rescues have taken place, according to local emergency management coordinator Billy Smith. He asked people to stay away from the downtown area on Tuesday amid its evacuation.
The interstate runs through Orange County, Texas, and CNN affiliate KTRK-TV reported that a mandatory evacuation was in effect for that area.
Massachusetts and Louisiana officials say flooding on the Pearl River may come a day later than expected.
