Monthly Eastern North Pacific Tropical Weather Summary

ABPZ30 KNHC 011844 CCA

800 AM PST THU DEC 01 2016

Corrected Ulika in summary table to show that peak intensity was
reached in the eastern North Pacific basin.

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

One named storm, Tina, formed in the eastern North Pacific basin in
November. In addition, Tropical Storm Otto moved into the basin from
the North Atlantic basin in November. Based on a 30-year (1981-2010)
climatology, a named storm forms in November in the basin only about
once every four years.

For 2016, the basin was quite active with 21 named storms that
occurred in the basin, along with 11 hurricanes, and 5 major
hurricanes. There was one unnamed depression and a second depression
that formed in the basin and became a tropical storm (Ulika) in the
central North Pacific basin before moving back into the eastern
North Pacific and becoming a hurricane. The level of activity in
2016 was above the long-term means of 16 named storms, 8 hurricanes,
and 4 major hurricanes.

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in the basin in 2016 was above normal. The ACE value for
the season was about 44 percent higher than the 1981-2010 median and
was the 9th highest ACE in the basin since reliable records began
in 1971. The period from July through September was especially busy,
with 18 named storms occuring, which is the most since 1971 in any
three-month time period.

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