Roslyn is forecasted to turn northeastward by this weekend and strengthen into a Hurricane by Saturday. Hurricane or Tropical Storm Watches could be issued later Thursday.
Tropical Storm Roslyn formed Thursday morning in the Eastern Pacific and is expected to become that basin’s next hurricane before impacting the Mexican coastline this weekend.
Roslyn is centered less than 200 miles south of Zihuatanejo, Mexico, or more than 300 miles south-southeast of Manzanillo, Mexico.
According to the FOX Forecast Center, maximum sustained winds are near 40 mph with higher gusts, and strengthening is forecast during the next few days. Roslyn is expected to become a hurricane by late Friday or Friday night.
Once its sustained winds reach at least 74 mph, Roslyn will be declared a Category 1 hurricane.
There are no watches or warnings in effect at this time, but watches will likely be issued for portions of the coast of southwestern or west-central Mexico later Thursday.

The FOX Forecast Center noted Roslyn’s expected track takes it over the warmest waters in the Eastern Pacific and into an environment that should allow significant strengthening.
On its forecast track, Rosyln could make landfall near the popular tourist destination of Puerto Vallarta this weekend.
WHY DON’T TROPICAL STORMS OR HURRICANES EVER HIT CALIFORNIA?
In addition to high winds, heavy rainfall will also be a threat, but due to the storm’s quick movement, accumulations should not be as significant as would otherwise be experienced.
Current indications suggest that 2 to 4 inches of rain is possible along coastal areas of Mexico’s Colima and Jalisco states, which might result in some flash flooding and possible landslides, especially in rugged terrain. Lower rainfall totals on the order of 1 to 3 inches are expected along coastal areas of Guerrero and Michoacán states.

Tropical Storm Roslyn is forecast to turn north and northeastward after moving inland and could bring locally heavy rainfall to coastal areas of Mexico’s Nayarit and southeastern Sinaloa states this weekend. The rainfall in these areas could also lead to flash flooding and possible landslides in the rugged terrain.
