Tropical Storm Aletta is spinning more than 440 miles off the southwestern coast of Mexico and using satellite data, NASA peered into the storm to uncover where the heaviest rain was falling.
Hurricane Aletta rapidly intensified to Category 4 intensity, but is quickly weakening.
The center of the storm was located about 455 miles west-southwest of Manzanillo, Mexico.
For now, it is too soon for experts to know whether this second storm would pose any direct threat to the Mexican Pacific next week.
The center said swells generated by Aletta would begin to hit portions of mainland Mexico and the west coast of Baja California Sur and continue through the weekend, likely causing "life-threatening surf and rip current conditions".
