Tom Kloza, chief analyst for the Oil Price Information Service, which tracks gas prices for AAA, estimated that the national gas price average could increase by 10 cents because Gulf of Mexico oil rigs are shutting down in preparation for Tropical Storm Isaac, CNN reports. Though Kloza also thinks the prices should go down fairly quickly after the storm.
The cheapest unleaded gas available in Northbrook, as of Tuesday afternoon, is $4.12 per gallon, at the Marathon. The price might inch toward $4.25 by Labor Day.
The National Hurricane Center predicts the tropical storm will become a hurricane on Tuesday with 74 to 95 mph winds. It is expected to hit from an area southwest of New Orleans to the edge of Florida's panhandle.
On Monday, the Washington Post reported Tropical Storm Isaac seems to be moving toward New Orleans, right around the seventh anniversary of Hurricane Katrina.
