CNN is somewhat backing this up:
Gas prices jump as much as 20 cents a gallon at some stations ahead of Hurricane Ike's landfall, says AAA; but increases modest at most stations.
Part of the article:
Prices nationwide
Prices have trended higher in the Midwest and Southeast partly due to production delays caused by Hurricane Gustav, said Tom Kloza from Oil Price Information Service, which provides the data for AAA. He noted that prices are expected to continue rising as Hurricane Ike churns through the Gulf of Mexico.
Nationwide, Alaska and Hawaii remained the two states with gas prices still tracking above $4 a gallon; Alaska at $4.393 and Hawaii at $4.336, AAA said. The cheapest gas continues to be found in New Jersey, where prices averaged $3.40 a gallon.
Gas remains about 10.7%, or 43.9 cents, below the record high average of $4.114 that AAA reported July 17. It's down 11.2 cents in the past month, but up 86.7 cents from a year ago.
Going forward, Kloza said Friday would be a "wild day" for gas prices, since some refineries - not just in coastal Texas but also inland Louisiana - have shut down in preparation for Hurricane Ike.
He said the nationwide average for gas prices could break the July 17 record as a result of the hurricane, but even if that happens, they would stabilize by October.
