Gas prices soar as Isaac hits land

DEARBORN, MI (AP)--   AAA Michigan says gasoline prices jumped 12 cents during the past day to a statewide average of about $4.05 per gallon as Hurricane Isaac made landfall.

The auto club said Wednesday's average for self-serve unleaded fuel was up from Tuesday's average of about $3.93.

Prices already rose ahead of the Labor Day weekend holiday, and AAA Michigan had predicted increases because of possible effects on oil production in the Gulf of Mexico.
