MIAMI - U.S. forecasters say Miriam is rapidly weakening and has been downgraded from a hurricane to a tropical storm well off Mexico's Baja California peninsula.
The National Hurricane Center in Miami said Miriam had top sustained winds of 70 mph (110 kph) at 5 a.m. EDT Wednesday, down sharply from a day earlier. The storm was centered about 430 miles (695 kilometers) west-southwest of the southern tip of the Baja peninsula.
Miriam is moving northwest at 6 mph (9 kph). No coastal watches or warnings are in effect and more weakening is expected.
In the open Atlantic, Tropical Storm Nadine remains far from land. It is about 530 miles (850 kilometers) south-southwest of the Azores islands with top sustained winds of about 45 mph (75 kph).
