Subtropical Storm Josephine (2026)

Storm Active: October 21-22

Around October 16, a strong cold front moved across the eastern United States and emerged over the Atlantic Ocean. The frontal boundary stalled over water, and a low pressure system formed along it and deepened over the following days. By October 21, the low was producing gale force winds and was located northwest of Bermuda. It shed its frontal characteristics and had enough convective organization to be designated Subtropical Storm Josephine that evening. At the time it was named, Josephine already had quite strong winds, with maximum sustained winds assessed at 65 mph.

The storm accelerated northeastward over the following day, its outer bands narrowly missing the northeast U.S. As it moved away from shore, Josephine began its transition to an extratropical cyclone, completing it by late on October 22. The cyclone continued to generate extremely strong winds as it moved out to sea; in fact these winds intensified to category 1 strength for a time before ultimately weakening.

The image above shows Josephine on October 22.

Josephine was a short-lived but strong subtropical storm, and in fact reached peak intensity after extratropical transition.

Hurricane Isaias (2026)

Storm Active: October 6-10

On October 5, an area of low pressure formed over the southwestern Gulf of Mexico. A broad area of rotation quickly became evident on satellite imagery, and favorable atmospheric conditions allowed it to consolidate into Tropical Depression Nine the very next day. The storm moved very slowly eastward at first in the sluggish steering currents of a trough to its north. Meanwhile, the circulation tightened up rapidly and the system began rapid intensification early on October 7, earning the name Isaias.

The storm picked up speed to the east-northeast and strengthened into Hurricane Isaias overnight. This marked the first formation of a hurricane in the 2026 Atlantic Hurricane season. No other Atlantic hurricane season in the satellite era (1960s onward) had ever gone without a hurricane all the way into October; going back further in history, the 1914 season was the most recent were no known hurricane formed before October 7 (in 1914, no known hurricanes formed at all, though before satellite technology, it is probable some storms were missed). A ragged eye feature appeared on the 8th and Isaias strengthened more as it turned northeast. An amplifying trough over the United States pulled the cyclone faster toward the coast and caused wind shear to increase dramatically over the storm. However, Isaias's motion aligned with the shear vector, insulating it from the worst effects. This allowed it to reach category 3 hurricane strength during the morning of October 9. The storm peaked in intensity with maximum sustained winds of 120 mph and a minimum central pressure of 959 mb.

Isaias's eye became cloud-filled and its structure degraded upon its final approach to the Gulf coast, but the hurricane was still a category 2 at landfall in the Florida panhandle during the evening of October 9. The eastern side of the circulation featured the worst winds and large spiral bands extended across the northern and eastern semicircles. The cyclone's interaction with the larger system to its north brought heavy rains all across the southeast U.S., even as it weakened rapidly over land. Isaias became post-tropical during the early morning hours of October 10. Nevertheless, its remnants continued to press northward across Alabama.

The image above shows Isaias near peak intensity as a major hurricane on October 9.

Isaias made landfall in the Florida panhandle as a category 2 hurricane; it was the first hurricane and major hurricane of the 2026 Atlantic hurricane season.
