MEXICO CITY (AP) _ Former tropical storm Blanca, which had whipped up winds and waves off Mexico's Pacific coast during its brief existence, died out Thursday in open waters, the U.S. National Hurricane Center said.

The center, based in Miami, said the storm's dwindling center was last located about 640 miles west of Acapulco. It said no further forecasts were expected, unless Blanca was to build up again.

The storm had been moving on a northwesterly track, paralleling Mexico's Pacific coastal states of Michoacan, Colima and Jalisco.

Earlier in the week, Blanca's strong winds whipped beach resorts and forced several southern Pacific ports to close. But there were no damage reports from Blanca, which briefly was the second tropical storm of 1997.

The first, Andres, killed two men and a woman in El Salvador last weekend.
