After a big drop a month ago, gasoline prices are pushing upward again in Nevada.
The statewide average for a gallon of regular unleaded is now $1.73 _ 8 cents cheaper than the middle of May, AAA Nevada said Wednesday.
But prices have bottomed out and are on their way back up across much of the state.
"After experiencing declining gas prices over the past couple of months, motorists may be forced to get back on the gas price roller coaster,"AAA spokeswoman Lisa Foster said.
"While prices continue to remain lower than they were a month ago, there are indications prices are on the rise again,"she said.
In addition to the normal summertime boost in demand, production problems at three California refineries have contributed to a jump in wholesale gas prices, Foster said.
In Reno, prices at the pumps are up a penny from last month to $1.75. Sparks has seen a 7-cent increase to $1.77. Carson City reports a 9-cent increase to $1.74.
Elko's gas is the cheapest in Nevada at $1.62, down a penny from last month, Foster said.
Las Vegas prices still mirror the state average at $1.74, down 8 cents from May.
Nationally, prices are up a penny to $1.51 for a gallon of regular unleaded.
With the onset of war in Iraq in March, average gas prices reached $1.97 in Reno and $1.99 in Carson City before plummeting in May.
