Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM PDT Sun Sep 1 2019

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

Tropical cyclone activity during August was below average for the eastern North Pacific basin, with three named storms forming during the month and none of them becoming hurricanes. Based on a 30-year (1981-2010) climatology, three to four named storms typically form during August, with two of those storms becoming hurricanes and one reaching major hurricane intensity. This is the first time since 1973 that no hurricanes have been observed in the basin during August.

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 2019 is below normal.

Reports on individual cyclones, when completed, are available at the National Hurricane Center website at: www.hurricanes.gov/data/tcr/index.php?season=2019&basin=epac
