Monthly Tropical Weather Summary

800 AM PDT Wed Nov 1 2017

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

Two tropical storms formed in the eastern North Pacific basin in
October, but neither attained hurricane status.  Based on a 30-year
(1981-2010) climatology, two named storms typically form in the
basin in October, with one of those becoming a hurricane.  A major
hurricane occurs in the basin in October in about 6 out of 10

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in October was below normal.  However, ACE has been
near normal for the season as a whole.

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