Oil prices hovered below $79 a barrel Monday in Asia as traders kept a close eye on damage a possible hurricane could cause rigs in the Gulf of Mexico this week, the Associated Press reported. Benchmark crude for August delivery was down 6 cents to $78.80 a barrel at early afternoon Singapore time in electronic trading on the New York Mercantile Exchange. The contract added $2.35 to settle at $78.86 on Friday. Tropical depression Alex, which has pounded parts of Mexico and Central America, is expected to regain strength in the coming days as it moves over warmer waters in the Gulf and possibly become a hurricane heading toward Mexico's Caribbean coast, the U.S. National Hurricane Center in Miami said Saturday. The storm will likely strike well away from the area where BP is trying to stop a massive oil leak, the center said. In other Nymex trading in July contracts, heating oil fell 0.80 cent to $2.1042 a gallon, gasoline dropped 0.38 cent to $2.1640 a gallon and natural gas was down 4.3 cents at $4.818 per 1,000 cubic feet. Brent crude was unchanged at $78.12 a barrel on the ICE futures exchange.
