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.
