Oil traded above $83 a barrel in Asia today as dealers watched a new storm developing in the Gulf of Mexico, which could impact oil production, dealers said.New York's main futures contract, light sweet crude, was 46 cents higher at $83.34 a barrel for November delivery in late morning trade.The contract had surged $2.58 to $82.88 in late US trades yesterday, when it edged closer to the all-time intra-day high of $84.10.Brent North Sea crude for November delivery was at $80.45, up 42 cents after breaching the $80-level for the first time in London, where the contract soared $2.60 yesterday.Tensions in the market were heightened on news that a storm developing in the Gulf of Mexico could affect oil production facilities, analysts said.According to the US National Hurricane Centre, a tropical depression was heading toward the coast of Mexico and could become a tropical storm.The Gulf of Mexico is a leading oil-producing region for the US and Mexico and investors are worried that, during the long Atlantic hurricane season that ends in November, a storm will damage oil rigs and other infrastructure."I think the storm sort of got people on edge," said Jason Feer, Asia Pacific vice-president and general manager of energy market analysts Argus Media, in Singapore.He said that while US crude stocks have been building, refinery run rates have dropped."That sort of indicates there's a potential bottleneck" heading into the North American winter when demand for heating oil picks up.
