October 2022 Tropical Cyclones Report

Summary

Fifteen named storms occurred across the globe in October. Five of those reached tropical cyclone strength (≥74 mph), and two reached major tropical cyclone strength (≥111 mph). The 15 named storms was the sixth most since 1981, but the numbers of tropical cyclones and major tropical cyclones were both below the 1991-2020 averages. The global accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) in October was the third lowest since 1981.

The Atlantic had three named storms including one hurricane: Julia. Hurricane Lisa was named on October 31 but became a hurricane on November 2. Both Julia and Lisa tracked through the western Caribbean and made landfall in Central America as hurricanes. The three named storms and one hurricane were both near normal but the ACE for October was below normal. The Atlantic hurricane season January-October remains near normal by most metrics.

The East Pacific had four named storms, including Hurricane Orlene which formed in September. The remnants of Hurricane Julia are also included as it maintained tropical storm strength across Central America and into the East Pacific. Three of those storms became hurricanes including two major hurricanes. These counts were above normal for October. However, the storms were relatively short-lived, so the ACE was near normal for October.

Hurricane Orlene rapidly intensified from a tropical storm to Category 4 within 24 hours before gradually weakening and making landfall in Mexico as a Category 1 hurricane. Three weeks later, Hurricane Roslyn followed a similar track that also included rapid intensification. However, Roslyn maintained Category 3 strength until making landfall in nearly the same place as Orlene. It was the strongest East Pacific landfall since Hurricane Patricia in 2015. Roslyn caused widespread flooding, landslides, and power outages.

The West Pacific had seven named storms in October, which was above normal. However, only two of those storms became typhoons and none became major typhoons, both of which are below normal. The October ACE was the fifth lowest since 1981. The North and South Indian Ocean also each had one named storm in October, which is near normal.

Data Description

The data in this report are derived from NCEI's IBTrACS dataset (Knapp et al. 2010; Schreck et al. 2014). IBTrACS tropical cyclone track and intensity data from agencies and sources around the globe. In this report, data from NOAA's National Hurricane Center (NHC) are used for the North Atlantic and East Pacific. The other basins use data from the U.S. Military's Joint Typhoon Warning Center (JTWC).

Historical values use the "best track" data that have been analyzed by forecasters after the season using all available data. Operational procedures and observing systems have changed with time and between regions, which makes these data heterogeneous. Intensity data are generally the most reliable since the early 1970s in the Atlantic (Landsea and Franklin 2013) and since the mid-1980s in other regions (Chu et al. 2002). The number of short-lived storms (≤2 days) has also increased since around 2000 due to improvements in observations and analysis techniques (Landsea et al. 2010).

Values for the current year are provisional values from the operational forecast advisories. IBTrACS obtains these from NCEP's TC Vitals, the NCAR Tropical Cyclone Guidance Project, and NHC provisional data. These values are subject to change during the post-season best track analysis. They also only include 6-hourly storm fixes, which means they may miss special advisories at landfall, peak intensity, etc.

The tropical cyclone seasons in the Southern Hemisphere begin in July and end in June, while the Northern Hemisphere seasons are counted from January to December. Storms are counted in all basins, months, and years in which they occur, which means some storms may appear more than once. However, the global totals only include each storm one time.
