As markets react to OPEC deal, pump prices move higher.

The national average price of gas sits at $2.37 per gallon—the most expensive average since June 2016—after prices climbed for 40 of the past 42 days.

AAA noted that the uptick is a result of market reactions to the OPEC oil cut agreement.

South Carolina ($2.14) and Tennessee ($2.14) are tied for the least expensive gas. Hawaii ($3.03) and California ($2.81) have the highest averages.

South and Southeast
The market remains well supplied with gasoline and prices are expected to continue to remain relatively low in comparison to other regions through the month, according to AAA.

Midwest
Regional Midwest inventories remain abundant and production from regional refineries is also high, but pump prices nonetheless remain volatile across the Midwest. AAA noted that monthly increases in Michigan (+34 cents), Wisconsin (+28 cents) Illinois (+27 cents), Ohio (+27 cents), Indiana (+26 cents) and Minnesota (+26 cents) rank in the nation’s top 10 largest increases.

Mid-Atlantic and Northeast
Retail averages steadily increased week-over-week.

Colonial Pipeline reported Sunday that they have shut down Line 19 near Chattanooga, Tenn. due to a suspected gasoline release. Line 19 delivers supply to Nashville, Tenn., from Atlanta, via Chattanooga, Tenn. An extended shutdown of Line 19 could result in supply issues in the Tennessee region and could also mean a possible back up of supplies into the Gulf Coast, AAA reported.
