As Tropical Depression Harvey moves farther from Texas, many locals are dealing with a new problem in its wake: a perceived gas shortage. While Texas Railroad Commissioner Ryan Sitton said Thursday that there is no reason to panic, many Central Austin residents have tried to refill their tanks only to find that gas stations are out of fuel or crowded with long lines. "There's a logistics issue," Sitton said, rather than a supply issue. As pipelines and refineries affected by the hurricane come back online and roads continue to open, supply trucks will be able to provide gas stations around Texas with gasoline from suppliers around the country. The national inventory of gasoline is 230 million barrels, which is more than enough to cover the few million barrel loss caused by Houston refineries that closed temporarily or are operating at reduced capacity because of flooding. But Sitton warned that if people rush to gas stations to fill up their tank out of fear that the supply will run out, they will cause an increased demand. "Even if all the refineries were running," Sitton said, "we'd still be having this issue." Many Austinites seem to have ignored this warning. Monday is Labor Day, and an increased number of drivers are anticipated to be on the road during the holiday weekend. If people cannot get gas or fear a continued shortage, however, they may cancel plans. On Twitter, some Texans posted the locations of gas stations that were out of gas or still had gas available. Others commented on the frenzy that the perceived shortage has caused.
