* Hurricane Irma possibly en route to Florida
* S&P energy index on track for best day in more than 2 months
* Newell Brands, Francesca's fall on weak forecasts
* Indexes up: Dow up 0.28 pct, S&P 0.25 pct, Nasdaq 0.11 pct (Updates to early afternoon)
Sept 6 (Reuters) - U.S. stocks were higher in early afternoon trading on Wednesday, helped by a bounce in energy stocks, but gains were limited due to worries over tensions on the Korean peninsula and a potential U.S. landfall of Hurricane Irma.
Exxon and Chevron rose about 2 percent, providing the biggest boost to the S&P, while a 2.3 percent rise in Home Depot shares propelled the Dow.
"What we see is the market correcting back from some of the reaction yesterday," said Lisa Erickson, head of traditional investments at U.S. Bank Wealth Management in Helena, Montana.
The S&P posted its biggest one-day loss in about three weeks on Tuesday after North Korea conducted its most powerful nuclear test yet on Sunday that triggered a dramatic escalation of the country's stand-off with the United States.
"In general, we continue to get a positive momentum on the economic side. While North Korea is still a wild card for certain, on the central bank front, both the ECB and the Fed are looking a little bit more dovish," Erickson said.
Three Federal Reserve policymakers on Tuesday expressed doubts about further rate hikes, with one influential policymaker calling for a delay in raising U.S. interest rates until the central bank was confident of a rebound in inflation.
Investors will focus on the Fed's Beige Book, a round-up of anecdotes on the health of the economy, that will be issued later in the day.
Also weighing on the sentiment is Hurricane Irma, which is en route to a possible Florida landfall at the weekend and comes days after Tropical Storm Harvey wreaked havoc in Texas and Louisiana.
At 12:29 p.m. ET (1629 GMT), the Dow Jones Industrial Average was up 60.12 points, or 0.28 percent, at 21,813.43 and the S&P 500 was up 6.06 points, or 0.25 percent, at 2,463.91.
The Nasdaq Composite was up 6.99 points, or 0.11 percent, at 6,382.56.
Six of the 11 major S&P indexes were higher. The energy index's 1.6 percent rise topped the gainers, putting it on track for its best day in more than two months.
Oil prices gained as strong global refining margins and the reopening of U.S. Gulf Coast refineries provided a more bullish outlook after sharp drops due to Storm Harvey.
Fed Vice Chair Stanley Fischer, a veteran central banker who helped set the course for modern monetary policy, said on Wednesday he would step down mid October.
Fischer's early departure gives President Donald Trump an opportunity to further shape the central bank sooner than expected.
United Continental fell 1.44 percent after it warned Hurricane Harvey and North Korea tensions would hurt its third-quarter results.
Newell Brands was off about 4 percent after the Sharpie maker slashed its profit outlook for 2017, while apparel retailer Francesca's Holdings was down more than 3 percent after its profit forecast fell below estimates.
