The U.S. National Hurricane Center says Newton has made landfall on Mexico's mainland and weakened to a tropical storm on its way to the U.S. border with potentially dangerous rains for Arizona and New Mexico.

The storm's maximum sustained winds early Wednesday are near 70 mph (110 kph) with rapid weakening expected as the center moves inland.

The storm is centered about 10 miles (15 kilometers) southeast of Bahia Kino, Mexico, and is moving north near 17 mph (28 kph). The Hurricane Center says Newton's forecast track will take it into southeastern Arizona in the afternoon.

It's the second landfall for Newton. The storm came ashore near Mexico's Los Cabos resorts Tuesday morning as a Category 1 hurricane with winds of 90 mph (150 kph).
