Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM PDT Sun Jul 1 2018

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

June was an extremely active month for tropical cyclone activity in
the eastern Pacific basin.  Six tropical cyclones formed, five of
which became named storms with two of the cyclones strengthening
into major hurricanes during the month. The six tropical cyclone
formations are the most on record for June, and the five named
storm formations in the month ties the June record set in 1985.

The number of major hurricanes that formed in the basin in June
also tied the June record last set in 2010.  Based on a 30-year
(1981-2010) climatology, two named storms typically form in the
month of June, with one of those becoming a hurricane.

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 2018 is well above normal.

Reports on individual cyclones, when completed, are available at
