Hurricane Frank formed in the Pacific Wednesday off the southwestern coast of Mexico but was headed out to sea, the National Hurricane Center said.
Sustained wind speeds reached 75 mph and the storm could strengthen in the next two days. However, it was not seen posing any threat to land, the storm center said.
Frank, the third Pacific hurricane of the season, is expected to swing west, northwest of Baja California through the weekend.
The storm has left at least three people dead in the southern Mexican state of Oaxaca.
