NORWALK - Gas prices have hit another new record overnight and experts expect that number to keep climbing.

AAA says the national average for a gallon of regular gas is now $3.45. In southwestern Connecticut, most drivers are paying more than $3.60 a gallon. Some say between the time they went to work and came home, prices jumped nearly 20 cents.

South Norwalk resident Angles Melendez says gas price increases force her to make some difficult decisions. "I live on a strict budget," says Melendez. "I'm a cancer patient so I'm living on $500 a month?I've had to limit myself on medications like buying for just two or three days so that I could put gas in my car."

Gasoline and Automotive Service Dealers of America Executive Director Michael Fox says the latest increase is put on gasoline that's already been stored at underground tank at gas stations because profit margins on a full underground tank aren't enough for fuel station owners to cover all their additional costs.

And Fox sees no end in sight for the increases.

"You're going to see $4 gasoline prior to Memorial Day. There's nothing in this market that's going to slow it down," Fox says.
