Andrea — 2025

Andrea formed from a low-pressure area along a decaying front in the central Atlantic. The system developed organized convection and became a tropical depression at 0600 UTC on 23 June 2025 about 425 nautical miles east of Bermuda, and it reached tropical storm strength by 1200 UTC that same day. Andrea was short-lived, remaining a small tropical storm through 24 June and weakening to a non-tropical low by 1800 UTC 24 June, then dissipating on 25 June. There were no landfalls. Andrea remained well east of Bermuda and did not approach any coastline, so no coastal watches or warnings were issued. Andrea’s peak intensity was 35 kt (40 mph) with an estimated minimum central pressure of 1014 mb, maintained from 1200 UTC 23 June through 1200 UTC 24 June. The storm never reached hurricane strength. Because Andrea stayed over open water and was small, there were no reports of storm surge or notable rainfall totals at land locations. No ships or land stations reported tropical-storm-force winds associated with Andrea. There were no reports of damage or casualties—no direct fatalities or reported injuries—and no coastal impacts. The central Atlantic east of Bermuda was the only region affected. Noteworthy points: Andrea had non-tropical origins and was a small system embedded in relatively high environmental pressure, which contributed to its relatively high central pressure for its wind speed. Post-analysis determined the system became a tropical cyclone about 30 hours earlier than was identified in real time, highlighting the challenge of detecting small systems with limited convection.
