MONTHLY TROPICAL WEATHER SUMMARY
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 AM PDT SAT OCT 01 2016

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

Four named storms formed in the eastern North Pacific basin during
the month of September.  A fifth, Ulika, formed in the eastern
North Pacific basin as a tropical depression but became a named
storm in the central North Pacific basin.  Four of these cyclones
became hurricanes, including Ulika, which strengthened to a
hurricane after moving back into the eastern North Pacific basin.
None of the hurricanes reached major hurricane intensity.  Based on
a 30-year (1981-2010) climatology, three or four named storms
typically form in the basin in September, with two becoming
hurricanes and one reaching major hurricane strength.

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in the basin so far in 2016 has been well above normal.
The ACE through the end of September is about 60 percent higher
than the 1981-2010 median value to date.

Reports on individual cyclones, when completed, are available at the
National Hurricane Center website at
www.nhc.noaa.gov/data/tcr/index.php?season=2016&basin=epac .
