Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM PDT Sun Oct 01 2017
For the eastern North Pacific, east of 140 degrees west longitude:
Four named storms formed in the eastern North Pacific basin in
September, with three of them becoming a hurricane and one a major
hurricane. Based on a 30-year (1981-2010) climatology, three 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
combined strength and duration of tropical storms and hurricanes,
activity in September was less than half of normal. So far in
2017, however, ACE has been above normal.
Reports on individual cyclones, when completed, are available at
the National Hurricane Center website at:
