(Reuters) - The U.S. National Hurricane Center on Friday tracked four low-pressure systems in the Atlantic, with two having a medium chance of forming a tropical cyclone, but holding no immediate threat to the oil-rich Gulf of Mexico.
One system, located about 1,000 miles west of the southern Cape Verde Islands, is moving westward at 15 miles per hour (24 kmph) and has a medium 30 percent chance of becoming a tropical cyclone in the next two days, down from 40 percent earlier.
Another system, located about 275 miles southeast of the southern Cape Verde Islands, has a medium 40 percent chance of forming a cyclone in the next 48 hours as it moves westward at about 15 to 20 mph (16 to 24 kmph).
