PERTH, Sept 1 (Reuters) - Oil rose nearly $2 to over $117 on Monday as U.S. energy companies reaced to shut down offshore oil production and flood-prone refineries in the Gulf Coast ahead of Hurricane Gustav, which is evoking memories of 2005's devastating Hurricane Katrina.
Forecasters predicted Gustav would be a major Category 3 hurricane by Monday morning local time, with top winds at around 200 kph (125 mph) when it slams into the Louisiana coast, west of New Orleans. (See [

U.S. light crude for October delivery <CLc1> rose $1.75 to $117.21 a barrel by 0016 GMT, after trading as high as $118.60 after the electronic market was opened.

London Brent crude <LCOc1> rose $1.43 to $115.48.
"This is definitely a dangerous storm but I think most of the market is in a wait-and-see mode and waiting to see (if there are) disruptions to oil facilities and pipeline infrastructure before they make a big move," said Gerard Burg, a commodities analyst at the National Bank of Australia in Melbourne.
"Investors are a lot more cautious now given the general bearish sentiments in the market."
Oil and natural gas companies shut down production across the Gulf of Mexico over the weekend to prepare for the Hurricane Gustav, possibly with a weaker punch than Hurricane Katrina, as coastal refineries braced for possible floods. [
