Three tropical storms active — Dexter, Henriette and Ivo — across Atlantic and Pacific
Three tropical storms — Dexter, Henriette, and Ivo — are active as of August 7. Dexter is becoming an extratropical cyclone, Henriette remains steady far from Hawaii, and Ivo is intensifying off Mexico, possibly reaching hurricane strength. No land threats, but hazardous seas expected.
AS of early August 7, 2025, multiple tropical systems are active across the Atlantic and Eastern Pacific basins, according to the latest advisories from the National Hurricane Center.
Tropical Storm Dexter, located in the North Atlantic, is transitioning into a strong extratropical cyclone as it accelerates east-northeastward away from land. Meanwhile, in the Eastern Pacific, Tropical Storm Henriette continues to move westward far from Hawaii with little change in strength expected, and Tropical Storm Ivo is intensifying rapidly off the southwestern coast of Mexico, forecast to become a hurricane within the next 36 hours.
While none of these storms currently pose a direct threat to land, marine interests are advised to monitor conditions closely as hazardous seas and strong winds are expected in affected areas.
