800 AM PDT Tue Oct 1 2024
For the eastern North Pacific, east of 140 degrees west longitude:
Two named storms formed in the month of September, one of which
became a major hurricane (John) in the eastern Pacific basin.
Tropical Storm Ileana formed earlier in the month and affected
southern Baja California Sur with tropical storm conditions. John
made landfall along the southern coast of Mexico as a category 3
hurricane late in the month.
The formation of two tropical cyclones is below the long-term
(1991-2020) September average of three named storms forming in the
month, and the formation of one hurricane is below the long-term
average of two. John becoming a major hurricane matches the
long-term September average of one major hurricane. The season to
date Accumulated Cyclone Energy (ACE), which measures the combined
strength and duration of tropical storms and hurricanes, is about 55
percent of the long-term (1991-2020) average.
Reports on individual storms, when completed, are available at the
