Gas prices spiked overnight and are up 10 cents a gallon since Hurricane Harvey struck Texas.
The national average price for a gallon of regular jumped nearly 5 cents to $2.45 a gallon on Thursday, according to AAA. And price spikes are even more severe in the Southeast -- up 17 cents in Georgia for the week and up 20 cents in South Carolina.
Gas futures shot up more than 10% Thursday, suggesting that prices will keep climbing.

"There's a worry now that most of the Texas refineries could be compromised for weeks rather than days" said Tom Kloza, chief oil analyst for the Oil Price Information Service, which tracks prices for AAA. He expects prices to climb by at least another 5 cents a gallon in the coming days, and that the national average could get as high as $2.75 a gallon in a worst case scenario.
The Trump administration tapped into the emergency Strategic Petroleum Reserve Thursday in response to the major refinery outages on the U.S. Gulf Coast caused by Hurricane Harvey.
Nearly 30% of the nation's refining capacity along the Gulf Coast has been shut or reduced operations due to flood waters associated with the storm. Motiva's massive Port Arthur refinery, the largest in the U.S., shut down on Wednesday due to "increasing local flood conditions," while Valero also closed its Port Arthur refinery on Wednesday.

Earlier in the week ExxonMobil's Baytown Texas refinery, which is the second-largest in the country, was shut down due to roof damage caused by heavy rain.
The refinery shutdowns caused the Colonial Pipeline to shut part of its operation from the Texas Gulf Coast because it doesn't have enough product to move through the pipeline. The pipeline is key to moving gasoline, jet fuel and other refined products to points along the East Coast from Florida to New Jersey. While part of the pipeline was still operating, "we don't know how much its carrying," Kloza said. "I'm sure it's less than maximum."
A break in the same pipeline in September 2016 caused gasoline shortages and prices to spike about 20 cents a gallon in Alabama, Georgia, North Carolina, South Carolina, Tennessee and Virginia.
The question now is how long it takes the closed refineries to get back online. Kloza said it took about six weeks for the system to get back to normal after Katrina.
