(Portland, OR) -- Gas prices continue to decline in Oregon, despite increases for most states. Triple-A reports Oregon's average declined two cents over the last week to four-03 a gallon. The national average went up two cents to three-52. It doesn't appear Hurricane Beryl will have a major impact on prices, but the hurricane season is just starting. If a storm effects oil production, prices could rise. Albany has the lowest average at three-81 a gallon. Portland has the highest average at four-14.
