Gas tracking website GasBuddy.com reported Friday gasoline prices were spiking in Northwest Indiana, following wholesale price increases and the shutdown of pipelines due to rain.
On Friday afternoon, many stations in Northwest Indiana already had prices near $4 a gallon. Prices early Friday morning averaged $3.62 a gallon, according to AAA's Daily Fuel Gauge Report.
"I expect stations to increase prices 10 to 25 cents per gallon over the next day or two with some stations starting to raise prices immediately," said Patrick DeHaan, GasBuddy.com Senior Petroleum Analyst, in a statement.
DeHaan said Thursday a price hike was likely in the Great Lakes area after wholesale gasoline prices spiked. DeHaan said changes in wholesale gasoline prices can lead to increases hours later, as stations pass along changes in the price they pay for gasoline.
Torrential rain has led to shutdowns of some pipelines in the region, according to GasBuddy, and refineries have also suffered setbacks as the region received record-breaking rainfall.
DeHaan also said that prices outside the Great Lakes would largely be unaffected as wholesale prices in other regions have only risen a few cents compared to the near 25-cent increase in wholesale prices in the Great Lakes region.
