US crude oil prices surged to a new record high of above 70 US dollars a barrel in opening trade on Monday amid concerns about supply shortages caused by coming Hurricane Katrina.

;Oil futures on the New York Mercantile Exchange soared to 70.8 dollars a barrel, beating the previous record of 68 dollars set last week, after producers and refiners shut down operations ahead of the Category 5 hurricane.

Katrina, measured as one of the four strongest storms on record, was expected to hit land at sunrise on Monday.

Seven southeast Louisiana refineries with a combined daily capacity of 1.45 million barrels per day (bpd) were shut alongside the Louisiana Offshore Oil Port, a major crude importing facility.

The Organization of Petroleum Exporting Countries (OPEC), which has been pumping at its full capacity for nearly a year, expresseddeep concerns over the buoyant prices.

"We are becoming increasingly concerned about the continuing high level of oil prices, which does not properly reflect the underlying fundamentals of the market," Kuwaiti Minister of Energy and OPEC President Sheikh Ahmad al-Fahad al-Sabah said in a statement.

He noted that current supply exceeds demand, leading to a buildup in stocks and stocks of crude and distillates are above their seven-year average.

"Oil resources and supplies are plentiful and OPEC has been producing 1.5 million more bpd than its quotas in the third quarter of 2005," Sheikh Ahmad said.

"Furthermore, demand is starting to slow down as a result of high prices," he said. "In view of these fundamentals, one expects to witness some price moderation."

OPEC meets on Sept. 19 to chart its future output policy.
