Mexico - Tropical cyclone IVO (ECHO 13 Aug 2025)Fri, 08 Aug 2025 10:19

A new tropical cyclone IVO formed over the Eastern North Pacific Ocean on 6 August, and it moved northwestward over the Ocean as a tropical storm with maximum sustained winds of 130 km/h along the southern coast of western Mexico.
On 8 August at 3.00 UTC, its centre was located offshore approximately 250 km east of the coast of Jalisco state in central-western Mexico, and 450 km south of Baja California, with maximum sustained winds of 93 km/h.
IVO is forecast to continue northwest as tropical storm over the sea, passing by the California Peninsula, strengthening to hurricane (cat.1) on 9 August. As of 10 August, it is expected to weaken to tropical storm.
It is unlikely that IVO will make landfall. Nevertheless it brought heavy rainfall and storm surge in southwestern Mexico as of 8 August, according to media.
On 8 and 9 August, more rainfall is expected over Michoacán de Ocampo, Colima, and Jalisco states.
