* Oil up over $2 a barrel on hurricane-related supply fear (Recasts, updates prices, market activity to late New York trade; adds second byline, dateline, previously LONDON)

NEW YORK/LONDON, Aug 26 (Reuters) - Gold ended higher on Tuesday as hurricane worries pushed crude oil higher, prompting buying of bullion that more than offset selling related to a dollar rally.
Gold <XAU=> was last at $822.90/824.30 at 2:15 p.m. EDT (1815 GMT), up from $820.20/821.40 an ounce late in New York on Monday.
"Everything is being led by external factors" such as oil and currencies, said VM Group analyst Matthew Turner.
Amid fears that Hurricane Gustav could disrupt output at key U.S. oil installations in the Gulf of Mexico, crude oil prices rose more than $2 a barrel. This supported buying of gold as a hedge against oil-led inflation.
Before rallying with oil, gold had dropped as low of $806.70 after the dollar scaled six-month peaks, sending the euro below $1.46. A jump in U.S. consumer confidence and expectations of interest rate cuts in the euro zone following weak German data buoyed the greenback. [
]"We saw a very sharp move this morning in favor of the dollar, which has accelerated what has been a recent trend in dollar strength against the euro," Fairfax analyst John Meyer said.
A stronger dollar pressures gold, making the precious metal more expensive for holders of other currencies. Also, gold often is bought as a hedge against weakness in the greenback.
An upsurge in physical demand for jewelry, coins and bars added some support to gold, although this was unlikely to counteract the effects of the strengthening dollar.
Jonathan Jossen, COMEX gold options floor trader in New York, said real demand could be seen for gold, but central bank selling has taken a toll on momentum.
On Tuesday, Sweden's central bank said it would sell up to 15 tonnes of gold over the 12 months to Sept. 26, 2009 and use proceeds to boost foreign currency reserves. [
]Demand was expected to pick up in the world's biggest gold market, India, ahead of the Hindi festival of Diwali in October.
Among other precious metals, silver <XAG=> climbed to $13.54/13.62 an ounce from $13.37/13.43 an ounce late in New York.
Holdings of the largest silver-backed exchange-traded fund, New York's iShares Silver Trust <SLV.A>, have risen to a record 6,474 tonnes despite the metal's recent price slide.
"We continue to think that silver prices are extremely vulnerable to any liquidation from the iShares silver ETF, which last week increased to a record size," said JP Morgan analyst Michael Jansen in a note.
"As such we continue to strongly believe that selling rallies is a very compelling risk/reward trade in silver especially, and in gold generally."
Platinum and palladium were relatively steady after recently suffering sharp falls.
Spot platinum <XPT=> ended lower at $1,409.50/1,429.50 an ounce from $1,420/1,440 late in New York, while palladium <XPD=> was lower at $282/290 an ounce from $285/293 an ounce, its Monday U.S. close.
