As lines get longer at gas stations across San Antonio, tempers seem to be getting shorter.
At several gas stations, frustrated drivers have gotten out of their cars to yell at each other. At one, a woman physically planted herself in front of a car to prevent it from cutting the line while another woman screamed at a car that had managed to sneak in.
GasBuddy, a gas price tracking firm, reports 270 stations in San Antonio were without fuel after 9:30 p.m., up from seven at 1 p.m.
Mayor Ron Nirenberg sought to calm the panic Thursday afternoon, reminding residents there was no widespread gasoline shortage but rather a delay in fuel production.
"San Antonio, there is no gas shortage," Nirenberg said. "As the result of delayed refinery operations caused by Hurricane Harvey, some stations have run low on gas."
He urged San Antonians to not be "misled by social media, which is causing people to panic and purchase more gas than necessary," and asked drivers to purchase gas as they normally would.
More than 20 percent of U.S. refining capacity is currently shuttered because of the storm, and gas prices are expected to spike, maybe up to 35 cents, in the coming weeks. Gas prices have already risen about 5 cents in San Antonio, according to GasBuddy.
Several gas stations began reporting running out of fuel Thursday morning. By the afternoon more stations were displaying "sold out" signs and as word spread on social media drivers began flocking to the pumps.
