Tropical Storm Andres became the eastern Pacific basin's first tropical storm of 2015 just before 8 a.m. PDT about 690 miles southwest of Manzanillo, Mexico.
Andres is expected to strengthen to a hurricane Friday.
Rapid intensification -- an increase in sustained winds of 30 knots or more in 24 hours or less -- is possible over the next day or so, due to low wind shear and warm sea-surface temperatures.
Andres should curl toward the northwest in a day or so, and will likely remain well off the Mexican coast, eventually weakening over colder water early next week.
High surf appears to be the most likely indirect impact along the Baja peninsula, including Cabo San Lucas, this weekend into early next week.
Some high surf may eventually propagate to Southern California beaches next week
