and a normal number of tropical waves. Instead, the inactivity was the result of the subtropical ridge being located further south than normal, which decreased the atmospheric instability across much of the basin. Such a pattern was different from the more active 1954 and 1955 seasons. Several tropical depressions formed that did not attain tropical storm status, many of which formed beneath an unfavorable upper-level trough. The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 54, which is categorized as being "below normal". ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding or tropical storm strength. Subtropical cyclones are excluded from the total. Systems Tropical Storm One A dissipating cold front off the southeastern United States spawned a low-pressure area on June 6. On the next day, the system organized into a tropical storm off the coast of North Carolina. The storm moved southward and reached peak winds of , based on reports from ships. During its duration, the storm failed to develop an inner core, affected by cool, dry air to the northwest. The structure was likely akin to a subtropical storm, based on its formation beneath an upper-level trough. On June 8, the storm accelerated to the northeast ahead of an approaching cold front, weakening to a tropical depression the next day, and becoming an extratropical cyclone within the front on June 10. The system dissipated later that day as a larger storm developed within the front. Tropical Storm Two In early June, a trough extended from the Gulf of Mexico to the western Atlantic Ocean. On June 12, the interaction between the trough and a tropical wave spawned a tropical depression in the Bay of Campeche. The newly developed tropical cyclone tracked northward, quickly intensifying into a tropical storm. It attained peak winds of on June 13, although it never developed a well-defined circulation. In addition, it had characteristics of both a tropical and extratropical cyclone, with cooler air aloft. Late on June 13, the storm made landfall near Cocodrie, Louisiana, and its lowest pressure of was measured over land, suggesting it did not weaken substantially after landfall. After moving inland, it
