"Retail gasoline prices finished last week quite strong in some areas on concern surrounding Hurricane Irene," said Patrick DeHaan, GasBuddy.com Senior Petroleum Analyst.
"The concern surrounding refinery production on the East Coast helped boost gasoline prices outside that area as well. The good news for motorists is that damage to refineries was likely minimal and gasoline production will resume soon. However, with Labor Day weekend fast approaching and these refineries taking days to resume production we still may see retail prices gradually climb during this week," DeHaan adds.
