A tropical storm that battered Central America over the weekend is driving the price of coffee higher.

Guatemala and El Salvador were hit hard by a tropical storm, which could damage production or delivery of coffee. Analysts say investors are worried about disease possibly hurting the crop as a result of flooding from the storm, though any drop in production is still speculative.

Coffee for July delivery rose 2.3 cents, or 1.7 percent, to settle at $1.3655 a pound.

Metals trading was mixed. Gold is getting another boost Tuesday after the euro fell to a new four-year low early in the day. Copper is falling following a report that says China's manufacturing sector is slowing.
