800 AM PDT Thu Oct 1 2020
For the eastern North Pacific, east of 140 degrees west longitude:
Tropical cyclone activity in the eastern North Pacific basin during
the month of September was slightly below average in terms of the
number of hurricanes that occurred. During the month, four
tropical storms formed, but only one reached hurricane strength.
Based on a 30-year (1981-2010) climatology, three-to-four named
storms typically form in the basin in September, with two of those
becoming hurricanes and one reaching major hurricane intensity.
In terms of Accumulated Cyclone Energy (ACE), which measures the
strength and duration of tropical storms and hurricanes, activity
in the basin so far in 2020 has been rather quiet, about 60 percent
below the long-term average.
