Today, tropical storm Roslyn will move near the coast of the central Mexican Pacific and will cause intense punctual rains (from 75 to 150 millimeters [mm]) in regions of Colima, Guerrero, and Michoacán, and strong (from 25 to 50 mm) in areas of Jalisco, as well as gusts of wind of 60 to 80 kilometers per hour (km/h) with waves of 2 to 4 meters (m) in height on the coasts of Colima, Jalisco, and Michoacán, and gusts of 50 to 60 km/h and waves of 2 to 3 m height on the coast of Guerrero.
At 10:00 am, Central Mexico time, Tropical Storm Roslyn was located approximately 225 kilometers (km) south-southwest of Punta San Telmo, Michoacán, and 305 km south of Manzanillo, Colima, with maximum sustained winds 100 km/h, gusting to 120 km/h and moving west-northwest at 11 km/h.
A Hurricane Warning is in effect for Puerto Vallarta. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion.
The rains could generate landslides, increase in the levels of rivers and streams, overflows, and floods in low-lying areas, for which the population and maritime navigation in the vicinity of Roslyn are urged to heed the warnings of the Meteorological Service.
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected to reach the coast within the hurricane warning area by late Saturday. Winds are expected to first reach tropical storm strength by midday Saturday, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion.
Hurricane conditions are possible within the hurricane watch area beginning Saturday night or early Sunday, with tropical storm conditions possible by Saturday evening.
Tropical storm conditions are expected within the tropical storm warning area on Saturday.
RAINFALL: Roslyn is expected to produce the following rainfall totals across coastal areas of southwestern and west-central Mexico:
- Guerrero and Michoacán and the lower coast of Colima: 1 to 3 inches
- Upper coast of Colima, Jalisco, western Nayarit including Islas Marias and southeastern Sinaloa: 4 to 6 inches with maximum amounts of 8 inches
This rainfall could lead to flash flooding and landslides in areas of rugged terrain.
STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding near and to the east of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves.
SURF: Swells generated by Roslyn are affecting portions of the coast of southwestern Mexico and will spread northward to the coast of west-central Mexico and the southern portion of the Baja California peninsula through the weekend. These swells are likely to cause life-threatening surf and rip current conditions.
