Weather forecasters say another tropical storm has formed along coastal Mexico.

Shortly after announcing Tropical Storm Barry off the country’s Atlantic coast on Saturday morning, the National Hurricane Center in Miami said Tropical Storm Flossie formed along Mexico’s west coast.

The storm’s center was about 240 miles south of Acapulco and about 485 miles southeast of Manzanillo. Its maximum sustained winds were clocked at 40 mph and it was moving west at 9 mph.

It is expected to become a hurricane Monday or Tuesday.

The storm may hit the Baja peninsula Thursday, according to the weather center. The western coast of Mexico is under a tropical storm watch.

In the Gulf, Tropical Storm Barry is expected to make landfall in Mexico later today.

And another area of interest in the Gulf may turn into a tropical storm that impacts Florida.
