Hurricane Aletta now becomes the first tropical storm of the eastern Pacific hurricane season on Thursday, and by the morning of Friday, it would have been upgraded to Category 4 monster. Strengthening rapidly overnight, the storm was rated Category 4 by Friday afternoon as it continued to churn in the waters off the west coast of Mexico.
The Hurricane Center said the storm could generate swells that cause life-threatening surf and rip currents over the coming days. It was centered about 300 miles (485 kilometers) south of Manzanillo, Mexico, and was moving northwest at 9 mph (15 kph).
If it becomes a tropical storm, it will be named Bud.
The Weather Channel reported Aletta is centered just under 500 miles south of Mexico's Baja Peninsula.
The average date when the first named storm forms in the Eastern Pacific Basin is June 10, according to NHC data from 1971 to 2009.

The Eastern Pacific hurricane season runs from May 15 through November 30.
The first hurricane, and the first major hurricane, of 2018 has formed (a major hurricane is considered a Category 3 or higher).
However, only one of these "A" hurricanes has reached Category 5 intensity, Hurricane Ava in June 1973, according to NOAA.
Eventually, Bud could help trigger a surge of moisture in the Desert Southwest where an increase in showers and storms may occur late in the week or next weekend.
While it may seem unusual for the Pacific's first storm to be so strong, Weather.com meteorologist Jonathan Erdman discovered it's not all that uncommon.
