Gas was up to $2.45 a gallon across the country, up from an average price of $2.35 a gallon last week.
That plant has not been hit by Harvey, which hammered Houston and the Gulf Coast with catastrophic flooding and shut about a quarter of USA refinery capacity.
Stephanie Milani with Triple AAA said, "We have seen dramatic price increases". October is a bit questionable. "Twelve states, including Maryland, Virginia and D.C. are allowing those states to sell less expensive winter blends gasoline earlier", Delise said.
"We heard there was going to be a shortage", one driver told CBS Dallas-Fort Worth. Gas prices in the region are up nearly 20 cents from this time last week, CBS Dallas-Fort Worth reported.
That's because several key ports along the Texas Gulf Coast were closed for most of the week, the critical Houston Shipping Channel was shuttered for several days and many local roadways have been unpassable.
"Great Lakes supply is fine".
The national average of gasoline per gallon is $2.51.
Among those states, the highest 24-hour rise on average was in South Carolina, AAA reported.
In another positive sign for the oil industry, Occidental Petroleum Corp OXY.N said it had reopened its Ingleside, Texas, crude export facility, near where Hurricane Harvey first made landfall last week.
"Northeast refiners are stepping in and barging supplies to the U.S. Southeast, the Caribbean, Mexico and South America to offset the lack of supply from Gulf Coast refineries and pipelines shut down due to Harvey", added Casselano. With nationwide gas supplies being high and seemingly less severe refinery damage, AAA says these increases should be less brutal than ones before. Rumors started online stated that the Houston-area was in a gas shortage, which caused a panic for citizens.
The release of 1 million barrels of oil is small compared to the demand faced in the U.S. per day of almost 20 million barrels of oil.
"Best case, the refineries should be up and operating again for the most part by the middle of September", said Hofmeister.
Major fuel arteries, including Colonial Pipeline, are struggling to find enough fuel to supply the Eastern Seaboard because of supply disruptions from Harvey, which has also taken at least 46 lives and damaged 100,000 homes.
