SYDNEY, Aug 9 (Reuters) - U.S. soybean prices inched higher on Wednesday, extending gains into a third session as fears over dry weather across key U.S. growing regions kept prices near one-week highs.
* The most active soybean futures on the Chicago Board of Trade had risen 0.2 percent to $9.74-3/4 a bushel by 0109 GMT. They firmed 0.4 percent on Tuesday after hitting their highest since Aug. 2 at $9.79-3/4 a bushel.
* The most active corn futures were up 0.2 percent at $3.84-1/2 a bushel, after closing down 0.8 percent in the previous session. The most active wheat futures were little changed at $4.56-3/4 a bushel. They ended Tuesday down 1.4 percent.
* The U.S. Department of Agriculture late on Monday rated 60 percent of the U.S. soybean crop in good-to-excellent condition, up from 59 percent a week earlier. However, ratings declined in Illinois and Iowa, the top two U.S. soy states.
* The latest weekly U.S. Drought Monitor showed 36 percent of Iowa in moderate drought and 7 percent in severe drought, up from 1.7 percent a week earlier.
* The market is also concerned U.S. soybeans are vulnerable to frosty conditions amid forecasts for cool temperatures for the rest of the month, a key development stage for the crop.
* Customs data showed China's July soybean imports surged 30 percent to their highest level since at least 2010.
* The European Union introduced a corn import tariff for the first time in nearly three years in view of low prices linked to swelling global supplies of the feed grain.
* The yen firmed slightly against the dollar early on Wednesday after North Korea said it is considering plans for a missile strike on the U.S. Pacific territory of Guam.
* Crude futures fell for a third day in early Asian trading as the market shrugged off a bigger than expected fall in U.S. inventories reported by an industry group as doubts linger over OPEC's ability to restrain supply as promised.
* U.S. stocks closed lower on Tuesday after a late afternoon selling spree as investors fled for safety after U.S. President Donald Trump vowed to respond aggressively to any threats from North Korea.
