Barbara — 2025

Barbara formed from a disturbance in the eastern North Pacific monsoon trough a few hundred miles south of the Gulf of Tehuantepec. Shower and thunderstorm activity became organized on 7 June, and a tropical storm was estimated to have formed around 0600 UTC 8 June about 150 nautical miles offshore of Guerrero, Mexico. The system moved generally northwestward, strengthened to a hurricane on 9 June, and then weakened while moving northward and northeastward away from the coast before dissipating early on 12 June. There were no coastal watches or warnings issued and Barbara remained offshore; therefore there were no official landfalls recorded for this storm. The best track shows the center stayed over open water and did not make landfall on the Mexican coast during its life cycle. Barbara reached a maximum sustained wind speed of 65 knots (75 mph) from 0600 to 1800 UTC 9 June, with an estimated minimum central pressure of 991 millibars. These values correspond to a Category 1 hurricane at peak intensity. Observed impacts were minimal. One ship (call sign 9V6864) reported tropical-storm-force winds of about 35 knots in Barbara’s northeast quadrant on 8 June. The NHC report notes no significant storm surge or large rainfall impacts associated with Barbara, and it lists no notable coastal surge heights or heavy-rainfall totals at named cities or counties. There were no reports of direct fatalities or significant damage associated with Barbara. The report states there were no significant casualties and no coastal watches or warnings were issued. One noteworthy point was forecast verification: NHC track forecasts at 12–36 hours were better than recent 5‑year averages, and intensity forecasts were generally better than recent averages as well. Several regional models overestimated interactions with nearby Tropical Storm Cosme and consequently produced larger track errors at 36–48 hours.
