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

Four named storms occurred across the globe in January. One of those reached tropical cyclone strength (≥74 mph), and none reached major tropical cyclone strength (≥111 mph). These counts are all below 1991-2020 averages for January. The global accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) was below average in January. No storms were active in the Northern Hemisphere, which is typical for January. On average, the West Pacific has a named storm in about four out of ten Januaries, and January storms are even less common in the other Northern Hemisphere basins.

The South Indian Ocean had the only tropical cyclone-strength storm in January: Cheneso. Cheneso made landfall in northern Madagascar as a tropical storm with heavy rain and flooding. It emerged over the Mozambique Channel and intensified to tropical cyclone strength before moving poleward and transitioning to an extratropical storm. Chenoso was the only named storm in the South Indian Ocean, which had below average activity for January. The South Indian Ocean season July-January has been near normal.

The only named storm in the Australian region was Tropical Storm Hale, which crossed 160°E into the Southwest Pacific during its brief life. This activity was below normal for Australia in January, but the season July-January remains near normal. Including Hale, the Southwest Pacific had three named storms, which is more than normal. However, all three were short-lived tropical storms, so the overall activity was less than normal for January and for July-January.

North Atlantic

No North Atlantic Tropical Cyclones occurred during January 2023.

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.
