Sticker shock at the gas pumps in California -- already high fuel costs jumped up 20 cents a gallon overnight because of shortages after a refinery fire in the Bay area back in August.
Inventories are at their lowest point in more than a decade.
California's fuel costs have gone up 40 cents in the past week.
Costco, which typically sells cheaper gas, has closed some stations.
A number of other stations have run out of gas.
The average price for a gallon in the Golden State is $4.49, but it's even more expensive in some California cities.
In Calabasas, a Low P gas station was charging $5.69 a gallon for regular unleaded. "It's not our fault" signs were seen on the pumps.
In other parts of the state, AAA says the cost was $4.59 in San Francisco, $4.53 in Los Angeles and $4.52 in San Diego.
In Arizona, the statewide average is $3.68. In Flagstaff, drivers are paying $3.89, $3.73 in Prescott, $3.66 in Phoenix, $3.52 in Tucson and $3.76 in Yuma.
This is normally the time of year when we see valley residents escape to the coast, but we didn't find any on Friday -- perhaps because of those crazy prices.
We did find a couple who was in town for business out of Los Angeles and they say the prices in California are brutal.
"I think it's ridiculous," said Linda Coburn, a California native, who was shocked by the valley's reasonable gas prices.
"They're actually pumps closed at our town," she said.
"They're locked in..no choice," said Duane McCully, who has family in California, but has put off a road trip because of the steep prices.
"It's worse there. I feel sorry for the folks," he said.
When drivers cross state lines, they'll be seeing about a dollar difference. In Arizona, the price just dropped to $3.69, but in California, prices at some gas stations are a whopping $5 a gallon.
"I'd rather be there than over there. Much better here because of gas prices," said Ray Serena.
Drivers like Serena are feeling fortunate to coast valley roads instead of California ones.
Is he hopeful prices will come down?
"I'm sure they will. They have to. People can't survive that kind of change," he said.
Reports say California drivers will likely see relief next week. According to GasBuddy.com, prices might continue to climb over the weekend.
