MONTHLY TROPICAL WEATHER SUMMARY
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 AM PDT SAT AUG 01 2015

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

Six tropical cyclones formed in the eastern North Pacific basin in July. Four of those cyclones reached tropical storm strength in the basin, while a fifth (Ela) became a tropical storm in the central North Pacific basin. The sixth cyclone (Tropical Depression Eight-E) did not reach tropical storm strength. Dolores and Guillermo reached hurricane strength, with Dolores also becoming a major hurricane.

The numbers of named storms, hurricanes, and major hurricanes that formed in the eastern North Pacific basin in July were normal. Based on a 30-year average (1981-2010), three or four named storms typically form in the basin in July, with two becoming hurricanes and one reaching major hurricane strength.

In terms of Accumulated Cyclone Energy (ACE), which measures the combined strength and duration of tropical storms and hurricanes, activity in the basin so far in 2015 has been above normal. The ACE through the end of July is about 200 percent of the 1981-2010 median value to date.

Reports on individual cyclones, when completed, are available at the website of the National Hurricane Center at http://www.nhc.noaa.gov/data/tcr/index.php?season=2015&basin=epac
