000 ABPZ30 KNHC 011249 TWSEP Monthly Tropical Weather Summary NWS National Hurricane Center Miami FL 700 AM PST Fri Dec 1 2017 For the eastern North Pacific, east of 140 degrees west longitude: No tropical cyclones formed in the basin in November. This is not unusual, however, with a named storm forming in the basin in November only once every 4 years based on a 1981-2010 climatology. For the 2017 season, 18 named storms formed, including 9 hurricanes and 4 major hurricanes. The number of named storms was above the long-term average of 15, while the number of hurricanes and major hurricanes was near the long term averages of 8 and 4, respectively. There were also two tropical depressions that formed that did not reach tropical storm strength. In terms of Accumulated Cyclone Energy (ACE), which measures the combined strength and duration of tropical storms and hurricanes, activity in the basin in 2017 was near normal. Despite the large number of tropical storms that formed in 2017, many of them were weak and/or short lived.
