Monthly Tropical Weather Summary

800 AM PDT Fri Nov 1 2019

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

Tropical cyclone activity during October was below average for the eastern North Pacific basin, with two named storms forming during the month. Neither of them became a hurricane. At the beginning of the month, Tropical Storm Narda was located near the west coast of Mexico, but it quickly weakened and dissipated later that day. Based on a 30-year (1981-2010) climatology, two named storms typically form in the eastern Pacific during October, with one of those storms becoming a hurricane and one reaching major hurricane intensity every other year.

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 near the long-term mean.

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
