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

May produced four named storms globally including two that reached tropical cyclone strength (74 mph). Both numbers were near normal. The global accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) was also near normal even though none of the storms reached major tropical cyclone strength (111 mph). The most impactful storm was Hurricane Agatha in the East Pacific. Agatha was the first named storm in the Western Hemisphere in 2022. It became the strongest hurricane to make landfall along Mexico's Pacific coast in May. It caused heavy rain and flooding there.

No storms formed in the Atlantic during May, which is typical. However, it broke a streak of seven consecutive years with a storm before the June 1 official start of the hurricane season. Hurricane Agatha was the only storm in the East Pacific, which was near normal.

There were also not any storms in May in the West Pacific, which is typically most active during June-October. The January-May activity for the West Pacific has been near normal in 2022. The North Indian Ocean had one hurricane-strength storm, Cyclone Asani, which is normal for May. Asani dissipated as it approached the east coast of India, which limited its impacts.

In the Southern Hemisphere, there was one named storm in the Australian region and another in the Southwest Pacific. Neither achieved tropical cyclone strength. Tropical Storm Gina caused heavy rainfall in Vanuatu, but otherwise neither storm had major impacts. This level activity is typical for the Southern Hemisphere in May.

North Atlantic

No North Atlantic Tropical Cyclones occurred during May 2022.

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.
