Hurricane Amanda began weakening on Monday and was not threatening land, but it remained a powerful Category 4 storm far off Mexico's Pacific coast. According to AP, the hurricane's maximum sustained winds Monday morning were near 135 mph (215 kph), down from a peak of 155 mph (250 kph) on Sunday, making it the most powerful May hurricane since the mid-1960s, when reliable records began to be kept. The U.S. National Hurricane Center said rapid weakening is expected over the next two days. The hurricane was centered about 680 miles (1,095 kilometers) south of the southern tip of Mexico's Baja California peninsula and was moving north-northwest near 5 mph (7 kph).
