(RALEIGH) -- Gas prices jumped an average of 39 cents per gallon since the uprising started in Libya last month, and prices are now at a two-year high. Across North Carolina businesses are starting to feel the pinch.

Greater Raleigh Chamber of Commerce President Harvey Schmidt said the high prices create a challenge heading into the second quarter.  "Well, from a big picture standpoint let's say it's a frost in late spring when you've got lots of businesses that are starting to poke their head out and suddenly get a cooling of the environment because of the gas prices," said Schmidt.

He added that it is tough for small businesses to make a profit under such conditions. "Ultimately it means fewer profits for small business and I'm afraid a slower return to economic strength and job creation."

Wholesale gasoline prices have risen 38 cents per gallon, or 15 percent, since the first uprising in Libya on Feb. 15. To compound the problem, in the next few weeks, gas prices are expected to rise as refiners make the season switch to a more expensive blend of gasoline designed to help protect against evaporation during the warmer summer months.
