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.
At 03:00 UTC on September 26 (21:00 MDT, September 25), the center of Tropical Storm "Rosa" was located about 720 km (445 miles) SW of Manzanillo, Mexico. The system had maximum sustained winds of 100 km/h (65 mph) and was moving WNW at 15 km/h (9 mph) with the minimum central pressure of 997 hPa.
