MIAMI (AP) -- Hurricane Barbara has formed in the Pacific and is headed toward Mexico's southern coast.
The U.S. National Hurricane Center in Miami says Barbara's maximum sustained winds are near 75 mph (120 kph), and the storm is expected to make landfall Wednesday afternoon.
A hurricane warning was issued in Mexico on Wednesday morning that covers an area in the Gulf of Tehuantepec from Puerto Angel to Barra de Tonala.
The storm was about 65 miles (105 km) east-southeast of Salina Cruz.
Officials in the southern coastal state of Oaxaca rushed to prepare emergency shelters and suspended classes for school children in coastal communities as rain began to lash the coast.
