800 AM PDT Thu Nov 1 2018
For the eastern North Pacific, east of 140 degrees west longitude:
October was above average in the eastern Pacific basin in terms of
the number of named storms that formed during the month (3). In
addition, two named storms (Rosa and Sergio) formed in September and
carried over into October. Two of these storms became hurricanes
and strengthened into major hurricanes during October (Sergio and
Willa). Based on a 30-year (1981-2010) climatology, two named
storms typically form in the eastern Pacific basin in October, with
one of those becoming a hurricane and one reaching major hurricane
intensity every other year.
In terms of Accumulated Cyclone Energy (ACE), which measures the
strength and duration of tropical storms and hurricanes, activity
in the basin thus far in 2018 has been above average, and 2018 is
the third most active season on record.
