(WFLX)- Gas prices could break the bank .
Prices could jump by 60 cents, or "more", per gallon by May, according to USA Today.
Analysts tell the paper prices should peak at $4.05 a gallon. But some markets will go "much" higher.
Prices usually rise in the spring, with higher demand and seasonal changes in gasoline formulations.
Unrest in the Middle East could also send gas prices higher.
