Richard weakens to a tropical storm over Guatemala

Hurricane Richard was downgraded to a tropical storm on Monday as it moved across northern Guatemala and southeastern Mexico after battering Belize. The storm was expected to further weaken to a tropical depression before it enters Mexico’s Bay of Campeche on Monday night or early Tuesday, the U.S. National Hurricane Center said. The bay produces more than two-thirds of Mexico’s 2.6 million barrels-per-day of crude output.
