MEXICO CITY (AP) — Hurricane Amanda rapidly gained force far off of Mexico’s Pacific coast Sunday, briefly becoming the strongest May hurricane on modern record for the Eastern Pacific before beginning to lose steam.

The U.S. National Hurricane Center in Miami said the main body of the category-4 hurricane posed little threat to land. It was centered about 720 miles (1,155 kilometers) south of the southern tip of Baja California late Sunday, and forecasters predicted it would rapidly weaken Monday while staying well out to sea at least through Friday.
