Hurricane Amanda has rapidly gained force far off of Mexico's Pacific coast and is now the strongest May hurricane on record for the Eastern Pacific, with sustained winds of up to 155 mph (250 kph).

The main body of the category-4 hurricane poses little threat to land, however. The U.S. National Hurricane Center in Miami says Amanda is centered about 770 miles (1,240 kilometers) south of the southern tip of Baja California and it's expected to stay out to sea while gradually weakening over the coming five days.

It's been moving to the north at 2 mph (4 kph).

Even so, Mexico's National Meterological Service says rains associated with Amanda are expected to drench much of western and central Mexico.

The Eastern Pacific hurricane season officially starts on May 15.
