Tropical Storm "Rosa" formed at 15:00 UTC on September 25, 2018, off the coast of Mexico as the 17th named storm of the 2018 Pacific hurricane season. The system is strengthening and is expected to become a major hurricane on September 27. Swells generated by Rosa will affect portions of the coast of southwestern Mexico and the southern Baja California Peninsula later this week into the upcoming weekend.
