MOSES LAKE — Gas prices in Washington hit a record high Monday at an average of $5.67. The previous record was set in 2022 at $5.56, according to AAA. 

Patrick De Haan, head petroleum analyst at GasBuddy, said there were sharp increases across the nation this week for both gasoline and diesel. He cited refinery outages and ongoing conflict in the Middle East as potential causes.  

“With so many moving pieces, the outlook remains highly fluid, and while some localized relief may emerge, broader price volatility is likely to persist in the near term,” De Haan said in a statement.  

In Grant County, there was a 23-cent increase from last week to Monday, bringing prices to a county average of $5.50. Grant County currently sits 17 cents under the state average.
