SYOSSET - Gas prices across Long Island are hitting highs rarely seen in the middle of winter.

AAA says the nationwide average for gas is at $3.73 a gallon. The price has risen 14 cents in the last week, and 43 cents over last month.

Experts with the Long Island Gas Retailers Association say the spike is likely due to the closure of several large refineries, coupled with rising crude oil prices and other production cuts.

If prices jump in the spring, officials say drivers could end up paying more than $4.50 a gallon.
