Gas prices are edging up across the country as the market continues to purge winter-blend gasoline to make room for summer storage. At $2.66, the national gas price average is five cents more expensive on the week and 11 cents more expensive than two weeks ago.

“Today, only 38% of U.S. gas stations are selling gasoline for $2.50 or less and that percentage will likely dwindle in coming weeks,” said Jeanette Casselano, AAA spokesperson, in a press release. “The holiday weekend, strong demand and preparation for summer gasoline are all factors that have driven and will continue to drive higher gas prices into early spring.”

Highlights include:

  • The nation’s top 10 largest weekly increases are: Utah (+14 cents), Kentucky (+10 cents), Missouri (+9 cents), Florida (+9 cents), Arizona (+9 cents), Idaho (+8 cents), Georgia (+8 cents), Nevada (+8 cents), New Mexico (+7 cents) and Indiana (+7 cents).
  • The nation’s top 10 most expensive markets are: Hawaii ($3.52), California ($3.51), Washington ($3.17), Alaska ($3.13), Oregon ($3.09), Nevada ($3.01), Pennsylvania ($2.86), Washington, DC ($2.83), Idaho ($2.80) and New York ($2.77).
