Subtropical Storm Josephine has formed in the North Atlantic Ocean, marking the 10th named storm of the 2026 season. NOAA had previously forecast a total of 18 named storms for this year, which spans from June 1 through November 30.
Why it matters
Storm activity is closely monitored due to the potential for rapid intensification, where a storm climbs by roughly two categories or more within 24 hours. Additionally, warmer air retains more moisture, which enables storms to generate higher volumes of rainfall.
NOAA has forecast up to nine hurricanes for the 2026 season, following a 2025 cycle that recorded 13 named storms and five hurricanes. The 2024 season saw hurricanes Helene and Milton cause $113 billion in damages and more than 250 deaths.
The players
NOAA
The National Oceanic and Atmospheric Administration is a federal agency responsible for monitoring oceanic and atmospheric conditions and issuing seasonal climate forecasts.
FEMA
The Federal Emergency Management Agency is tasked with coordinating the federal government's response to natural disasters.
The details
Rapid intensification remains a critical concern for forecasters, as storms can escalate in severity within a single day. Increased atmospheric moisture from warmer air temperatures continues to drive concerns regarding extreme rainfall events, similar to historic benchmarks.
Timeline
June 1, 2026: Start of the Atlantic hurricane season.
Late May 2026: NOAA issued its initial seasonal storm forecast.
Early August 2026: NOAA issued a revised seasonal storm forecast.
October 21, 2026: Subtropical Storm Josephine observed in the North Atlantic.
November 30, 2026: End of the Atlantic hurricane season.
Seasonal Patterns
The emergence of Josephine fits within the context of recent intense Atlantic hurricane activity, following the $113 billion in damages caused by hurricanes Helene and Milton in 2024. The 2026 season continues a trend of high-volume named storm counts monitored by NOAA since the start of the season.
Residents in coastal areas should monitor local weather advisories and verify emergency evacuation routes. It is also recommended to review household disaster preparedness plans as the hurricane season remains active through late November.
The takeaway
The development of Josephine serves as a reminder that the Atlantic hurricane season remains a threat until it officially concludes on November 30. Staying informed about meteorological updates is essential for those living in regions susceptible to storm-related rainfall and wind damage.
