Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM PDT Tue Aug 01 2017
For the eastern North Pacific, east of 140 degrees west longitude:
This July was quite busy in the eastern North Pacific basin, with
five named storms forming, four of which became hurricanes. Two
of the hurricanes, Eugene and Fernanda, reached major hurricane
strength. One unnamed tropical depression also formed in July.
Based on a 30-year (1981-2010) climatology, three to four named
storms typically form in the basin in July, with two becoming
hurricanes and one of those reaching major hurricane intensity.
In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in July was more than 2.5 times the average activity for
the month, making it the fifth most active July on record. The
ACE for the season to date is almost twice the average.
Reports on individual cyclones, when completed, are available at
