Puerto Vallarta, Mexico - The first tropical storm of the eastern Pacific hurricane season, Tropical Storm Amanda, formed Thursday afternoon as a tropical depression about 635 miles south-southwest of Manzanillo, Mexico, and is expected to continue drifting toward the west or west-northwest over the next several days. It is no threat to land.

The U.S. National Hurricane Center in Miami says Amanda had maximum sustained winds of 64 kph late Friday morning. It was centered about 998 kilometers south-southwest of Manzanillo, Mexico, and was moving west-northwest at 8 kph.

How strong this system ultimately becomes is still subject to uncertainty, given the potential for stronger winds aloft providing wind shear later this weekend. If that scenario does not occur, it's possible we could be looking at a hurricane during the Memorial Day weekend.

To reemphasize, according to weather.com, this system is not expected to threaten land.
