Residents along the coast have begun evacuating coastal areas and moving inland, while those staying put have been stocking up on essentials.
The storm preparations have led to some fuel shortages, with Reuters reporting several gas stations in the region have run out of gas.
"There have been some spotty outages of certain products in some areas," said Michael Fields, executive director of the South Carolina Petroleum Marketers Association, whose members include convenience store operators. "With a million people leaving the coasts and coming inland, there's going to be some issues."
The southeast U.S. is largely supplied with fuel via Colonial Pipeline, which carries more than 3 million barrels per day of gasoline, diesel and other fuels to markets in the southern and eastern United States. Its operator was preparing for potential flooding and loss of power, the news agency reported.
Impact at the Pump
Earlier this week, AAA cautioned that motorists in the affected area could see a rise in gas prices, at a time when prices remained relatively stable across the U.S.
"A storm like this typically causes an increase in fuel purchases in the market and a slowdown in retail demand. Motorists can expect spikes in pump prices to be brief, but possibly dramatic," said Jeanette Casselano, AAA spokesperson.
She added AAA is monitoring the storm and will provide updates and the latest gas prices online at GasPrices.AAA.com.
Though prices are expected to rise, officials in Virginia, North Carolina and South Carolina this week warned against price gouging by retailers, citing penalties for violating state of emergency rules against excessive price increases, Reuters reported.
On Sept. 10, North Carolina Gov. Roy Cooper also took steps to ensure that the state has enough fuel for people evacuating ahead of the storm and for preparation and recovery efforts. He signed Executive Order No. 53, waiving certain fuel vapor regulations to ensure adequate supply of fuel as Hurricane Florence approaches.
