Note: This report catalogs recent tropical cyclones across the North Atlantic and East Pacific and places each basin’s tropical cyclone activity in a climate-scale context. It is not updated in real time. Users seeking the real time status and forecasts of tropical cyclones should visit The National Hurricane Center.

Summary

Global tropical cyclone activity remained quiet in November. Six named storms were active in November, which is near normal. However, there are typically around four hurricanes and two major hurricanes, but this November had none of either. The global ACE for November was the lowest on record since 1981. The 87 named storms for January-November 2021 remains near normal, but the 33 tropical cyclones and 14 major tropical cyclones are both at least tied for the fewest since 1981.

The Atlantic hurricane season officially ended November 30. The 21st and final named storm was Tropical Storm Wanda, which formed on October 31 and continued into the first week of November. Wanda developed from the remnants of a strong nor'easter that created significant wind and rain along the East Coast, but the subsequent tropical system remained over the ocean with minimal impacts. This one named storm in November was near normal. For the season as a whole, the 21 named storms was the third most on record behind 2020 (30) and 2005 (27). The seven hurricanes and four major hurricanes were both near normal. The accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) was above normal for 2021.

The East Pacific had two named storms both of which were active November 7-8. There is typically a named storm once every 2-3 Novembers, but this is the fourth year in a row with at least one. In addition, Sandra and Terry were active simultaneously, which is the first time this has occurred during November. Overall, the 2021 East Pacific hurricane season activity was mixed. The 20 named storms were above normal, the eight hurricanes were near normal, and the two major hurricanes were below normal. The ACE was also below normal for 2021.

The West Pacific continued to be particularly quiet in November with only one named storm (normal is around three). Nyatoh formed on November 29 and became a major typhoon in December, but it was only a named storm during November. In the Southern Hemisphere, Tropical Storm Paddy near Australia became the first named storm of the 2021-2022 Southern Hemisphere season.

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 basin's 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.
