For the eastern North Pacific, east of 140 degrees west longitude:

After no named storms formed in the eastern North Pacific basin in
May or June for the first time since 1969, tropical cyclone
activity in July was well above average.  Seven named storms formed
in the basin in July, with five of those becoming hurricanes and
three becoming major hurricanes. In addition, a tropical depression
(now Tropical Storm Howard) formed on 31 July.  The number of
hurricanes sets a new record for the most hurricane formations in
July, and the numbers of named storms and major hurricanes tie
previous records for the month.  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,
this was the second most active July in eastern North Pacific
history, behind July 1992.  The ACE for the season to date is well
above normal.

Reports on individual cyclones, when completed, are available at the
National Hurricane Center website at
