Summary

Both the Atlantic and the East Pacific had unusually active starts to their hurricane seasons. The Atlantic tied a record with three named storms in June. The total of four named storms for the year through June ties 2012, 2016, and 2020 for the most on record. Similarly, the East Pacific had four named storms in June, which tied for the 4th most on record. The total of five for the year through June tied a record as well. The early season activity in both basins in particularly noteworthy because it is unusual for them to be active at the same time.

Most of the storms in the Atlantic and East Pacific were weak and short-lived. Hurricane Enrique in the East Pacific was the only storm in either basin to reach hurricane strength or last more than 48 hours as a named storm. As a result, the accumulated cyclone energy (ACE; a measure of the strength, duration, and frequency of tropical cyclones) has been near-normal in both basins. Tropical Storm Claudette was arguably the most impactful tropical cyclone in June as it brought heavy rain, wind, and tornadoes across the southeast.

Outside of the Western Hemisphere, tropical cyclone activity was relatively quiet. The West Pacific had two named storms, including Typhoon Champi, which was near normal. However, the ACE was only about one-third of normal in June and one-fourth of normal for the year to date. No storms formed in any of the other basins in June, which is not unusual. Even so, the nine named storms that formed globally during June fell one short of the record of 10 that formed in June of 1997 and 2018. Enrique and Champi were the only hurricane strength storms, so the ACE was still below normal.
