* Iran says OPEC to support prices at September meet
* Tropical depression forming, limiting price decline (Updates throughout, changes dateline from LONDON)
NEW YORK, Aug 25 (Reuters) - Oil prices slipped on Monday as demand worries due to surging fuel costs outweighed supply concerns caused by a tropical depression in the Caribbean.
U.S. crude <CLc1> fell 34 cents to $114.25 a barrel by 1:22 p.m. EDT (1722 GMT), after falling more than 5.4 percent on Friday in the largest one-day slide since Dec. 27, 2004. Brent crude <LCOc1> traded down 31 cents to $113.61 a barrel.
Oil has tumbled from a record high over $147 struck on July 11 on growing signs demand in the United States and other consumer nations has faltered due to surging fuel costs.
"All the factors that have motivated the price down are still intact," said James Crandell, analyst for Lehman Brothers.
"(There are) demand concerns and also increasing supply."
The U.S. National Hurricane Center said an area of low pressure over the central Caribbean Sea formed into Tropical Depression Seven and could become the season's latest tropical storm later Monday. [
]According to forecast tracks, two of six forecasters expect the system to head northwest into the Gulf of Mexico, where there is a high concentration of U.S. oil and natural gas production. Four other forecasts show the system headed toward Belize or the Yucatan Peninsula, however.
Worries over the storm helped counter strength in the dollar earlier Monday. Investors have used commodities as a hedge against inflation and the weak dollar this year.
"Judging from the dollar's gains, crude oil should be down a lot, but that is not the case as a developing storm in the Carribean Sea appears (to be) supporting oil," said Phil Flynn of Alaron Trading in Chicago.
Further support on Monday came from ongoing tension between the West and Russia over Georgia and expectations that oil exporter group OPEC, which meets on Sept. 9, could trim production should prices fall further.
Moscow's military intervention in Georgia has disrupted some shipments of Azeri oil through Georgia.
Russia, which began to pull out the bulk of its forces from Georgia last week, said on Saturday its troops would patrol one of Georgia's main Black Sea ports, defying Western demands for a complete pullback.
Russian lawmakers on Monday urged the Kremlin to recognize two rebel regions of Georgia, a move seen as likely to worsen relations with the West. Russia said its troops would patrol one of Georgia's Black Sea ports, Poti.
Iran's oil minister said on Monday he expected OPEC to work on preventing the falling trend in crude prices and also to study oversupply in the market when it meets on Sept. 9 in Vienna. [
]Venezuela said on Friday OPEC should consider cutting oil production at the meeting if it decides that recent price declines constitute a sustained downturn.
An OPEC source, however, said, the cartel is likely to keep oil output policy unchanged. [
]The Organization of the Petroleum Exporting Countries, the source of two in every five barrels of oil, boosted output further in August, according to industry consultant Petrologistics on Friday.
