The national average price of gasoline eked out a small decline over the last week, with some states seeing a drop of 5-10 cents per gallon, while new issues in some states, like Arizona, have caused prices to jump notably in others, according to Patrick De Haan.

The head of petroleum analysis at GasBuddy said with California facing a deluge of water from Tropical Storm Hilary, some level of refinery problems that could impact gasoline prices could arise, and with eyes on a more active Atlantic, the next few weeks will bring additional volatility to what motorists can expect at the pump.

Average gasoline prices in Texas have risen 4 cents per gallon in the last week, averaging $3.45/g Moday, according to GasBuddy’s survey of 13,114 stations in Texas.
